Description

[0001] This invention relates to non-earthquake building system which can be applied on all kinds of separate regime buildings, which eliminates the destructive effect of the earthquake, the loss of lives and property in medium and severe intensity earthquakes, by damping earthquake forces acting on the building inside two foundation structures which move independently of each other without transferring the earthquake forces from the building's foundation to upper floors.

[0002] Earthquake is known as a natural disaster the effects and time of which cannot be precisely determined. The fact that the effects and time of the earthquake cannot be determined precisely causes the measures required to be taken for the future remain limited.

[0003] Measures which can be taken against earthquake comprise alterations made on the building structure and statics to enable the building to maintain its integrity during an earthquake, and shelters, automatic gas-power cut off systems to prevent incidents like fire, collapse and explosions during the earthquake.

[0004] In the building project, prepared before the building is constructed, building static calculations are made for estimated earthquakes. The building is constructed according to the static calculations made. However, precise analysis relating to the behavior of the building during the earthquake cannot be performed from estimated conditions and earthquake intensities. Statics calculations are made for two directions and no calculation method exists for earthquakes which come transversally or from the bottom. Therefore, the durability of the building can be maintained within the statics calculations made and the conditions specified. In unexpected situations, the wear brought about by the passing of long years and earthquakes which cannot be estimated prevent having information related to the time-endurance of the building. In this manner the building becomes more dangerous.

[0005] There exist various systems which are placed during the construction of buildings for the buildings to remain erect during an earthquake. Systems such as rail systems, rubber skidders, energy absorption springs, pre-tensioned cables absorb the earthquake forces created by the earthquake. However, these systems cannot be implemented on all kinds of buildings. Additionally these systems, despite providing protection against earthquake, their costs are considerably high.

[0006] This invention, which can be applied on all kinds of separate regime buildings, which relates to a non-earthquake building system that eliminates the destructive effect of the earthquake and prevents loss of lives and property in medium or severe intensity earthquakes by damping the earthquake forces within two foundation structures moving independently of each other in impact cantilevers before the earthquake forces acting on the building are transferred from the foundation of the building to the upper floors, entirely overcomes the above described disadvantages and is characterized in that; it comprises a new foundation embodiment which prevents the transfer of earthquake forces to the upper floors of the building, by dampening them by virtue of the foundations located on the building's foundation and which are located on top of each other, and movement mechanisms and impact cantilevers located in between the said foundations, no matter by which angle earthquake forces come on the horizontal and/or vertical plane, and prevents the building from tipping over due to centrifugal force by virtue of the rigid area of the structure.

[0007] It can be applied in separate regime structures of all types regardless of their geometric structure, the number of floors, with or without basements, with the area of the basement or floors larger than the building's main mass and entirely surrounding the main structure.

[0008] There are two foundations in the building which are independent of each other. The first foundation is among the most important structural elements of the rigid structure body which sits on the natural ground, which has impact cantilevers, external curtains, reinforced concrete support panels surrounding it, and anchored to the ground by tension piles. Structural loads are transferred to the ground by this foundation. The structure's own weights transferred to the second foundation are transferred to the first foundation by the movement mechanical located in between the two foundations. The second foundation, on the other hand, is the foundation which is located under the moving structure, which sits on the first foundation with it movement mechanism, which has foundation cantilevers around it. The structure's moving body is constructed on the second foundation. No matter which direction earthquake forces come from they can move opposite the direction of the earthquake in all directions without an angle on the movement mechanism located in the second foundation under each column. This system which is fully articulated does in no way transfer neither the earthquake moments nor the shear forces to the superstructure. Around the 1st foundation, on the other hand, which is anchored to the ground via tension piles, there are impact cantilevers and on the top end sections of the impact cantilevers there are external curtains. The reinforced concrete cap is the steel element which is connected to the moving structure and protects the building travel cavity from foreign materials.

[0009] There are two foundation embodiments in the building's foundation which can move independently of each other. When earthquake forces come from different directions the two foundations moving independently of each other prevent the earthquake forces to reach the upper floors.

[0010] In the building's foundation, while the two foundations are moving independently of each other the earthquake forces are transformed into impact forces by virtue of the impact cantilevers. After the earthquake forces are transformed into impact forces, while the wedges bear a portion of the impact force, at the same time, when the foundation cantilever impacts on the impact cantilever it dampens a portion of the impact force. At the same time it softens the impact of the foundation cantilever and the impact cantilever.

[0011] In the event of an earthquake the tension piles prevent the tipping over of the building under the earthquake effect. Tension piles operate on pressure force when there is no earthquake and on tensile force during earthquake. The dampening of earthquake forces in the building's foundation prevents destructive effect of earthquake forces from reaching the upper floors and eliminates loss of lives and property. The non-earthquake building system which eliminated earthquake risk offers a permanent measure against earthquake.

[0021] This invention, which relates to a non-earthquake building system which can be applied on all kinds of separate regime buildings, which eliminates the destructive effect of the earthquake, the loss of lives and property in medium and severe intensity earthquakes, by damping earthquake forces acting on the building inside two foundation structures which move independently of each other without transferring the earthquake forces from the building's foundation to upper floors, comprises in general, 1st Foundation (1) the fixed foundation which anchors the building to the ground, the 2nd Foundation (2) moving on the 1st Foundation (1), the foundation cantilever (3) of the 2nd Foundation (2), the impact cantilever (5) as the steel element surrounding the 1st Foundation (1), the external curtain (6) which is the bears ground actions and forms a structural cavity, the earthquake wedge (6) which dampens a portion of the impact energy during the impact of the foundation cantilever (3) to the impact cantilever (4), the movement mechanism (7) which provides the articulated move between the 1st Foundation (1) and the 2nd Foundation (2), the support panel (8) which is the structural element which enables ground actions to be safely carried by the external curtain (5) and increases the strength of the impact cantilever (4), the reinforced concrete cap (9) which prevents foreign material from entering the structure travel cavity, and the tension piles (10) which are the structural elements that prevent the structure connected to the 1st Foundation (1) from tipping over.

[0022] The utilization of the invention is as follows:

[0023] The 1st Foundation (1) is the structural element of the rigid area of the building which is sunken in the ground. The 1st Foundation (1) is implemented in the state of the art in the form of laying a foundation at a certain depth of the ground with foundation laying methods.

[0024] The 2nd Foundation (2) is a foundation structure, which can move independently on the 1st Foundation (1) and carries the building floors (2) on itself. The 2nd Foundation (2) is located at a certain distance above the 1st Foundation (1). The 1st Foundation (1) together with the 2nd Foundation (2) support the whole structure. The structure rises on the 2nd Foundation (2) with the building floors (2). On the 2nd Foundation (2) structural columns (1) are erected.

[0025] The foundation cantilever (3) is the structural element surrounding the 2nd Foundation (2). It continues in the same dimensions and thickness throughout the circumference of the 2nd Foundation (2). It enables the internal forces of the earthquake to be consumed.

[0026] The impact cantilever (4) is the structural element at the tip of the 1st Foundation (1) which goes around the 1st Foundation (1). The impact cantilever (4) surrounds the foundation cantilever (3) located in the 2nd Foundation (2). During an earthquake the foundation cantilever (3) impacts on the impact cantilever (4). With this impact the earthquake internal forces are consumed.

[0027] The external curtain (5) is the structural element at the tip of the impact cantilever (4) forming the structural cavity which bears the ground actions on the impact cantilever (4). It increases the strength of the impact cantilever (4) in the event the building tips over during an earthquake.

[0028] The earthquake wedge (6), on the inner surface of the impact cantilever (4), dampens a portion of the impact forces formed during the impact of the foundation cantilever (3) to the impact cantilever (4) and at the same time softens the impact of the foundation cantilever (3) and the impact cantilever (4).

[0029] The movement mechanism (7) is the mechanism which provides support and movement between the 1st Foundation (1) and the 2nd Foundation (2). The movement mechanism (7) enables the 2nd Foundation (2) to move independently and in all directions on the 1st Foundation (1) during an earthquake. At the same time it is the structural element which transfers the building's own weight to the 1st Foundation (1).

[0030] Support panels (8) are structural elements which increase the strength of the external curtain against ground loads around the external curtain (5) located on the top end portion of the impact cantilever (4) around the 1st Foundation (1). During the strike of the foundation cantilever (3) to the impact cantilever (4) the strength of the impact cantilever (4) increases. The top elevation of support panels (8) is at ground level (3).

[0031] The residential reinforced concrete cap (9) is the structural element which prevents foreign material entering the structure's travel cavity.

[0032] The tension pile (10) increases the hold of the 1st Foundation (1) in the ground and prevents the building tipping over during an earthquake. The tension pile (10) has foundation pile arms which are connected to the foundation and which advance at an angle towards the ground. The number of tension piles (10) vary according to the need, building height and soil structure. Due to the angular layout of the arms of the tension pile (10), it creates additional tension force in the ground by virtue of the shear resistance of the ground above itself. The tipping off of the building is prevented by virtue of the tension pile (10). The tension pile (10) is poured on the ground at an angle and within reinforcement before the 1st Foundation (1) is formed and on it the 1st Foundation (1) is seated. When no earthquake is present, the ground safety of the building against settling in the ground is increased with tension piles (10) with the compressive strength formed by the building's own weight.

[0033] In the non-earthquake building system, after the process of preparing the ground for foundation laying is completed; the tension piles (10) are made on the ground, with a determined number of arms and angles. After the completion of the tension piles (10) the 1st Foundation (1) is formed in connection with the tension piles (10). The impact cantilever (4), external curtain (5) and support panels (8) are made around the 1st Foundation (1). When the impact cantilever (4) is formed the earthquake wedge (6) is placed in the inner part of the impact cantilever (4).

[0034] On the 1st Foundation (1) the movement mechanism (7) is placed. On the level of the movement mechanism (7) in the form remaining above the 1st Foundation (1) is filled with filling material. The filling material, which does not prevent the horizontal movement of the building, acts at the same time as formwork for the 2nd Foundation (2). The 2nd Foundation (2) is formed on the filling material. When the 2nd Foundation (2) is being formed, the foundation cantilever (3) which surrounds the 2nd Foundation (2) is formed together with the 2nd Foundation (2). The building floors (13) are continued on the 2nd Foundation (2). After the filling material is placed in the internal surface of the impact cantilever (4) and the internal surface of the external curtain (5) the installation of the reinforcement is made. Afterwards the concrete laying and impact cantilever (4) and the structure travel cavity are formed. The filling material forms the internal formwork of the impact cantilever (4) and the external formwork of the foundation cantilever (3) produced in the second stage and serves the function of cavity. With the filling material placed in between the impact cantilever (4) and the forces the structure's travel cavity is formed.

[0035] The behavior of the non-earthquake building during an earthquake in the event the earthquake waves come in the horizontal or vertical planes;

[0036] In the event earthquake waves come in the horizontal plane from right to left; the 1st Foundation (1) moves in the earthquake direction (14) together with the ground. With the movements of the earthquake waves, the 2nd Foundation (2) moves on the 1st Foundation (1) in a direction opposite to the earthquake direction (14). Together with the 2nd Foundation (2) the building moves opposite to the earthquake direction (4) in the building's movement direction (15). During this movement in the first movement the right foundation cantilever (3) impacts on the impact cantilever (4) on the right hand side. When the foundation cantilever (3) impacts on the impact cantilever (4), earthquake forces are converted to impact forces and a portion of them are dampened by the impact cantilever (4). The earthquake wedge (6), which is located in the inner part of the impact cantilever (4) dampens a portion of the impact forces during the impact of the foundation cantilever (3) to the impact cantilever (4) and softens the impact. During the time the force caused by earthquake waves is trying to tip the building over, the foundation cantilever (3) located on the left hand side makes an upward movement and strikes the bottom surface of the impact cantilever (4) on the left hand side. The impact cantilever (4) also dampens the impact force formed in the vertical direction. In the bottom section of the inner surface of the impact cantilever (4) there is also an earthquake wedge (6) and dampens a portion of the impact force. The tipping force is transferred to the tension pile (10) and the tipping of the building is prevented.

[0037] In the event earthquake waves come in the horizontal plane from left to right; the 1st Foundation (1) moves in the earthquake direction (14) together with the ground. With the movements of the earthquake waves, the 2nd Foundation (2) moves on the 1st

[0038] Foundation (1) in a direction opposite to the earthquake direction (14). Together with the 2nd Foundation (2) the building moves opposite to the earthquake direction (14) in the building's movement direction (15). During this movement in the first movement the left foundation cantilever (3) impacts on the impact cantilever (4) on the left hand side. When the foundation cantilever (3) impacts on the impact cantilever (4), earthquake forces are converted to impact forces and a portion of them are dampened by the impact cantilever (4). The earthquake wedge (6), which is located in the inner part of the impact cantilever (4) dampens a portion of the impact forces during the impact of the foundation cantilever (3) to the impact cantilever (4) and softens the impact. During the time the force caused by earthquake waves is trying to tip the building over, the foundation cantilever (3) located on the right hand side makes an upward movement and strikes the bottom surface of the impact cantilever (4) on the right hand side. The impact cantilever (4) also dampens the impact force formed in the vertical direction. In the bottom section of the inner surface of the impact cantilever (4) there is also an earthquake wedge (6) and dampens a portion of the impact force. The tipping force is transferred to the tension pile (10) and the tipping of the building is prevented.

[0039] In the event earthquake waves come in the vertical plane from the bottom up; because all foundation cantilevers (3) and impact cantilevers (4) operate in the vertical direction simultaneously, the destructive forces of the earthquake are met in a safer manner.

[0040] Earthquake waves coming in the mentioned directions and planes may come by acting both on the horizontal and the vertical plane in a manner acting on more than one planes. In that event it is possible for the system behavior to operate simultaneously during the ne moment of earthquake. By virtue of this when an earthquake wave which acts in more than one plane--for example, an earthquake wave which has effect in both the vertical and the horizontal planes--is encountered, the mentioned behaviors can operate simultaneously.
