摘要：Aiming at the low horizontal lateral stiffness and restoring force, taking advantage of hyperelastic property of shape memory alloys, a new type of shape memory alloys wire-laminated rubber combined bearings is developed by fixing shape memory alloy wire diagonally around conventional laminated rubber bearings. Through comparison test on seismic simulation shaketable, analysis is made on effects and rules of displacement amplitude of isolation layer on seismic isolation basic parameters of shape memory alloys wire-laminated rubber combined bearings such as unit cycle energy consuming, equivalent horizontal stiffness, maximum restoring force, and equivalent damp ratio. Favorable seismic isolation property of shape memory alloys wire-laminated rubber combined bearings is verified.
