  • Publication number: 20150107166
    Abstract: 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.

  • Patent number: 8973887
    Abstract: In a slide structure, a support structure and a seismically isolated structure, a first sliding surface (25) of a sliding member (21) is formed of a sliding body (24) made of synthetic resin. A film (27) made of synthetic resin and having a Young's modulus more than twice as large as that of the first sliding surface (25) is formed on the second sliding surface (28) of the counter member (22). At the same time, fine irregularities having a maximum height Rz of 3 ?m or higher are formed on the surface of the film (27). As a result, the lubricant is trapped in small pits of the irregularities to prevent the lubricant from flowing out, and a stable low friction state can be maintained.

    Abstract: A portal frame 3 made of wide flange sections without braces is fixed to the external surfaces of an existing RC-column 5 extending in the vertical direction and to the external surfaces of existing RC-beam 8 extending in the horizontal direction of a reinforced concrete building. The wide flange section column 4 fixed to the existing RC-column 5 is assigned a bending rigidity roughly equivalent to that of the existing RC-column 5, thereby reducing the stress additionally occurring at the connecting part between the existing RC-column 5 and column 4 by deforming the column 4 similarly to the existing RC-column 5 under the horizontal load transmitted from existing RC-beam 8 and/or wide flange section beam 6 during an earthquake. Using a steel portal frame without braces preserves the building appearance and avoids bracing which may block windows while increasing earthquake resistance.

  • Patent number: 6662506
    Abstract: A collapse-resistant frame system (10) for a bridge or building structure includes a plurality of mechanically-interconnected columns (12) and beams (14). At least the lowermost columns are formed of a material (28) that exhibits quasi-elastic behavior in response to seismic excitation, while the beams of the frame system are formed of a material (22) that exhibits elastic/plastic behavior, such that quasi-elastic flexure of the columns under seismic loading will cause plastic hinge formation in the beam ends (26) to thereby dissipate the rotational energy without significant plastic hinge formation in the column bases.

  • Patent number: 6631593
    Abstract: A bi-directional sliding pendulum seismic isolation system for reducing seismic force acting on a structure by sliding pendulum movements, each system comprising a lower sliding plate forming a sliding path in a first direction, an upper sliding plate forming a sliding path in a second direction, and a sliding assembly for reducing the seismic force of the structure by performing a pendulum motion by sliding along the lower and upper sliding plates.

  • Patent number: 6474030
    Abstract: The present invention relates to a technique wherein a complex structure is adopted as a joint structure between each head of plural piles (1) and a bottom of a footing (2), and the complex structure may be selected among either a complex of a roller bearing structure (Y) interposing a sliding member (12) and a pin bearing structure (X) interposing a sliding member (32), another complex of a rigid joint structure (Z) and the roller bearing structure (Y), or still another complex of the rigid joint structure (Z) and a pin bearing structure (X). This can restrain the rotation of an upper structure (A), reduce stress concentration applied to a joint portion and occurrence of a bending moment on the pile (1) in applying a great external force such as an earthquake thereto, prevent damages or destroys of the joint portion and the pile, and also enhance excellent positional restoration performance for restoring the upper structure (A) to an initial position thereof, after the earthquake happens.

  • Patent number: 6324795
    Abstract: A seismic isolation system with a plurality of ball-and-socket joints attaching a base structure to a plurality of foundation pads or piers. A plurality of pads or piers 3, 13 form a foundation structure. A seismic isolation bearing 20 attaches a pad to the floor 1 of a building or other structure. The seismic isolation bearing includes a joint 22 attached to an elastic element 12. The seismic isolation bearing allows tilting of the pad in relation to the base structure in response to vertical movement of a foundation pad. Additionally, rotation of the joint works in conjunction with the elastic element to reduce the shear deformation in the elastic element in response to transverse movement of the foundation pad.

  • Patent number: 6289640
    Abstract: The seismic isolation sliding support bearing system includes a pair of sliding bearings, which can be moved relatively to each other and are arranged in opposition and in contact with each other between a superstructure and a substructure. At least one of the pair of sliding bearings is a sliding bearing (a) made from a molding, having a porous structure including a plurality of voids, of a composition including PTFE as a main component and aromatic polyester resin, or a composite including a base member having the molding on the surface thereof. Furthermore, a lubricant holding layer for holding a flow lubricant in the voids is formed in a surface portion of the molding. Since the sliding bearing (a) has a high compression elastic modulus (of 900 MPa or more) and a low coefficient of friction (of 0.02 or less) and can maintain the low friction for a long period of time, it can be particularly effectively used in a seismic isolation sliding bearing support system for structures with a large load.
