【摘要】 以提高SMA利用率为目的,设计了几种不同形式的SMA橡胶支座并进行了耗能试验。研究了水平位移幅值、水平加载频率以及竖向荷载等因素对SMA橡胶支座水平刚度、耗能量以及阻尼等基本力学性能的影响,结果表明,新型的SMA橡胶支座均可有效提高橡胶支座的耗能性能和回复能力,并为SMA橡胶支座优化设计提供了依据。更多还原

【Abstract】 As the aim of improving the utilization ratio of SMAs in SMA-rubber seismic isolation bearings,several different SMA-rubber seismic isolation bearings were designed,and energy dissipation experiments were done.The factors which affect the level stiffness,energy dissipation and equivalent damping ratio of SMA-rubber seismic isolation bearings including level displacement amplitude,level loading frequency and vertical load were studied.Result showed that the new SMA-rubber seismic isolation bearings have better hysteresis and energy dissipation capabilities.It provided the base to optimize the SMA-rubber seismic isolation bearings.更多还原
