| 摘 要： | 利用粘弹性阻尼器的有限元模型,推导出了粘弹性阻尼器支撑单元的附加刚度矩阵和等效节点力向量,通过拟力实模态叠加处理非比例阻尼,编制了粘弹性阻尼器受控结构的弹性时程分析程序,并对一装设粘弹性阻尼器的16层钢筋混凝土受控结构和相应原结构在多遇地震下的响应进行了分析、对比,结果表明:装设粘弹性阻尼器后,结构的地震响应可以得到明显的降低.

| Abstract: | Based on the finite element model of viscoelastic damper(VED),the additional stiffness matrix and equivalent node force vector of the VED bracing unit were derived.The pseudo-force real mode superposition was used to deal with the non-proportional damping and a program for elastic time history analysis of reinforced concrete structure was established for analyzing the controlled structure with VEDs.A 16-story controllable reinforced concrete structure with VEDs and the original structure without VEDs were analyzed and compared on the condition that earthquake frequently occurs.The analyzing results indicate that earthquake responses of the controlled structure can be reduced remarkably. |
