| 摘 要： | 实际工程中,由于没有通用软件可以应用、设计人员对带螺栓板式橡胶支座的抗震性能认识不一致,因而使支座设计成为整个结构设计的薄弱环节.通过采用ANSYS大型通用有限元分析软件,详细分析了螺栓对实际工程常采用的板式橡胶支座抗震性能的影响.结果表明:螺栓可有效提高板式橡胶支座的水平刚度,改善其滞回性能.

| Abstract: | In actual projects,since there is no universal software to be applied and the levels of designers’ are different,so the aseismatic performance of laminated rubber bearings with bolts has not been affirmed.Thereby the design of bearings becomes the weakest link of the structural design.By means of ANSYS large-scale general-purpose software of finite element analysis(FEA),the effect of the bolts on the aseismatic performance of laminated rubber bearings has been analyzed in detail.The result shows that the bolts may effectively improve the horizontal stiffness and hysteretic performance of laminated rubber bearings. |
