20080222975 | SLIDING-TYPE LAMINATED PLATE BEARING AND STRUCTURE - The sliding-type laminated plate bearing is provided with a laminated portion at which a plurality of hard rigid members and a plurality of soft elastic members are laminated alternately in a state of being wholly or partially non-adhesive, a first smooth member of which the surface is made smooth and which is in contact at least with either end face of the laminated portion in the laminated direction, and a second smooth member which is in contact with the first smooth member and which is installed so as to be slidable with respect to the first smooth member. | 09-18-2008 |
20080289268 | SEISMIC STRUCTURAL DEVICE - A link-fuse joint resists bending moments and shears generated by seismic loading. A joint connection includes a first plate assembly having a first connection plate including a first diagonal slot formed therethrough. A second plate assembly has a second connection plate including a second diagonal slot formed therethrough. The second diagonal slot is diagonally opposed to the first diagonal slot. The second connection plate is position such that at least a portion of the second diagonal slot aligns with a portion of the first diagonal slot. A pin is positioned through the first diagonal slot and the second diagonal slot. The joint connection accommodates a slippage of at least one of the first and second plate assemblies relative to each other when the joint connection is subject to a seismic load and without significant loss of clamping force. | 11-27-2008 |
20110011013 | FLOOR-PANEL AND FLOOR-PANEL ASSEMBLIES - The present invention provides a floor panel that affords a seismic isolation effect against large-magnitude quakes. A floor panel comprises a sliding unit that comprises a floor unit member having a lower portion that can come into contact with a base member and an upper portion supported on the lower portion; and a panel member having a structure fixing face that can be fixed to an upper structure, and an abutting face that abuts an upper face of the upper portion of the floor unit member, such that the abutting face is provided so as to be slidable on the upper face. The floor panel also comprises an elastic insert member provided between a wall and a side face of the panel member of the sliding unit. | 01-20-2011 |
20150107166 | SYSTEMS AND METHODS FOR PROVIDING BASE ISOLATION AGAINST SEISMIC ACTIVITY - A seismic isolation system including a base plate having a textured top surface and a top plate positioned above the base plate having a non-textured bottom surface, wherein desired coefficients of static and kinetic friction between the top plate and the base plate prevent relative movement of the two plates with normal operation and yet allow the top plate to move relative to the base plate during a seismic event. In one example, the sliding surface has a coating such as a polyester (e.g., polyester triglycidyl isocyanurate) or a low surface energy coating (e.g., silicone-epoxy coating). In another example, the seismic isolation system further includes a damping system comprising internal dampers within a concrete slab resting on the top plate to provide displacement control. | 04-23-2015 |
