摘要

某竖向刚度突变结构采用NosaCAD有限元软件建立整体结构分析模型,在文中分析结构在7度多遇和罕遇地震下的弹塑性时程反应,得到结构在地震作用下的变形、内力和破坏情况的变化过程.并与振动试验台作出相应对比.最后根据构件的受力及损坏情况,给出了设计改进建议.
The structural analysis model of structure with mutational vertical stiffness was established with NosaCAD.In this paper,the seismic behavior of the structure under the frequent and rare intensity of 7 degree earthquakes was studied.Based on the analysis,the deformations,internal forces and damage patterns of the structure were investigated.At the same time,comparison between the model and the vibration table test was made.Finally,according to internal forces and load-carrying capacity or damage state of element,suggestions for improving the seismic design were given.
