空斗墙砌体结构检测与非线性有限元动力分析
|
摘要
本文对村镇住宅中常用的空斗墙砌体结构进行抗震性能研究。通过对武汉汉南区某二层空斗墙砌体结构进行动力检测,根据现场测试结果,建立了空斗墙结构的非线性有限元模型,对其进行了反应谱分析和动力时程分析,对该空斗墙结构抗震性能进行了评估。本文还通过对不同构造的空斗墙砌体结构进行对比分析,讨论了影响空斗墙砌体结构抗震性能的各种关键因素,为空斗墙结构抗震评估和抗震设计提供了依据。
In this paper,the seismic behavior of cavity wall structure commonly used in the countryside is studied.A real two-story cavity wall structure which is in Hannan district of wuhan city is chosen to do dynamic test.According to the test results,the cavity wall structure of nonlinear finite element model was established.The response spectrum analysis and the dynamic time-history analysis of the finite element model were carried out,and the anti-earthquake behavior of the cavity wall structure was evaluated.In addition,according to the comparative analysis of different tectonic cavity wall structure,the key factors that may affect the seismic behavior of the cavity wall structure such as the ring beam and the constructional column were discussed.Finally the effects of seismic behavior of cavity wall structure caused by different factors were summarized.The result of the analysis can provide the reference for cavity wall structure anti-earthquake assessment and design.
