NUMERICAL SIMULATION ANALYSIS OF SEISMIC ISOLATION STRUCTURE USING SMA WIRE-LAMINATED RUBBER COMBINED BEARINGS

摘要：

Aiming at the low horizontal lateral stiffness and restoring force, taking advantage of hyperelastic property of shape memory alloys (SMA for short), a new type of SMA wire-laminated rubber combined bearings is developed by fixing SMA wire diagonally around conventional laminated rubber bearings.Numerical simulation and comparison analysis of a four-story frame structure is carried out for three cases, that is, without seismic isolation bearings, with conventional laminated rubber bearings and with SMA wire-laminated rubber combined bearings. And the results confirm that SMA wire-laminated rubber combined bearings can greatly improve the seismic isolation effects.
