基于ANSYS的空斗墙片墙抗侧力性能研究
|
摘要
空斗墙房屋由于造价低廉,在我国很多农村地区都有应用。但是我国现行的抗震设计规范未涉及空斗墙房屋,故对其抗震性能的研究并不多。与此同时,一旦发生地震,空斗墙房屋的破坏又往往是最严重的。所以如何评估空斗墙房屋的抗震性能,成为很多研究工作者的课题。先用ANSYS软件建立墙体有限元模型进行数值模拟,然后对实际墙体进行伪静力试验,最后将试验值与计算值对比分析,研究了空斗墙房屋底层片墙的抗侧力性能,对现有的空斗墙房屋抗震性能的研究提供了一些参考。
Due to the low cost of cavity wall buildings,the structure is well accepted in rural areas of our country.However,it is not covered by the code of seismic design in our country and so there are less studies on its seismic performance.Meanwhile,this type of the structure is weak in an earthquake.Therefore it is a hot topic to study the cavity wall buildings' seismic behavior.In the paper,numerical simulation of finite element model was applied based on ANSYS,and then pseudo-static test was used for a real wall in order to study the lateral seismic behavior of bottom walls in cavity wall buildings for the purpose to provide some references for the study of seismic behavior of exsisting buildings.
