【摘要】 对一种新型锥形非固结支座进行静力力学性能试验,基于试验分析了锥形非固结支座在不同参数影响下水平力学性能的变化关系,得出面压和材料厚度对支座的耗能能力和水平等效刚度有较大影响的结论。同时,用ABAQUS对锥形非固结支座的滞回曲线进行数值模拟,结果与试验曲线能较好地吻合。最后,提出了适合锥形非固结支座滞回曲线的计算模型。更多还原

【Abstract】 This paper introduces a new unbonded conical bearing.Horizontal shear property tests under different parameters(including displacement,pressure,frequency,slope angle) are accomplished.Based on the test analysis,it is found that the pressure and thickness of rubber are two key factors to the property of bearing.Meanwhile,the hysteretic property is studied with FEM program ABAQUS.The result of numerical simulation coincides with the tests.Finally,a hysteresis loop model is proposed.更多还原
