采用三维空间模型的静力弹塑性分析方法、弯剪型层模型的非线性时程分析方法相结合的静动力分析法,对江苏宿迁某19层剪力墙结构进行了黏滞阻尼消能减震分析。首先对该结构进行了三维空间静力弹塑性分析,得到了该结构的层间恢复力曲线;在此基础上,建立了该结构的弯剪型层模型,进行了非线性时程分析,并研究了非线性黏滞流体阻尼器对高层剪力墙结构地震响应的振动控制。结果表明:采用静动力分析法可以评估剪力墙结构的弹塑性抗震性能,为工程结构设计提供参考,为类似结构提供借鉴。
By using the static elasto-plastic analysis method of three-dimensional space model and the nonlinear dynamic analysis method of bending-shear layer model, the viscous damping energy dissipation of a 19-story shear wall structure in Suqian of Jiangsu Province was carried out. Seismic analysis. The three-dimensional static analysis of the structure is carried out, and the layer’s restoring force curve is obtained. On this basis, the shear-and-shear layer model of the structure is established and the nonlinear time history analysis is carried out. The vibration control of nonlinear viscous fluid damper on the seismic response of highrise shear wall structures is studied. The results show that the static-dynamic analysis method can evaluate the elasto-plastic seismic performance of the shear wall structure, provide reference for engineering structure design and provide reference for similar structures.
