| 摘 要： | 在总结框架试验研究成果的基础上,运用动力时程分析方法,对有施工缝框架和整浇框架的非弹性抗震性能进行了研究.采用层间剪切模型和三线性恢复力模型,分别输入8度多遇地震和7度罕遇地震作用下的迁安地震波、El Centro地震波和天津地震波,对两个框架的弹塑性地震反应进行了模拟.将有施工缝框架和整浇框架的顶层位移、层间最大位移、层间最大剪力进行了对比分析.模拟结果表明:有施工缝框架和整浇框架,在迁安波、El Centro波和天津波的作用下,结构顶层的位移时程曲线和加速度时程曲线随着地震动时间的变化规律是基本一致的.

| Abstract: | On the basis of the frame experiment,the inelastic seismic response characteristics of testing frame with construction joints and monolithic cast frame are studied by dynamic time-history method.Using interface layer shear model and the trilinear restoring force model,the elastic-plastic seismic responses of two frames are simulated by inputting Qian'an earthquake waves,El Centro earthquake waves and Tianjin earthquake waves under 8 degree frequently-occurred earthquake action and 7 degree seldom-occurred e... |
