摘要
地裂缝是西安市的一种特有的地质灾害,以考虑基础梁的框架结构为研究对象,基于有限元软件SAP2000,采用位移加载方法来模拟地裂缝引起的不均匀沉降,对结构顶部侧移以及对框架结构底层框梁和框柱进行内力分析.通过对在地裂场地下考虑基础梁的上部框架结构的性能影响分析,提出在地裂场地下框架结构的设计依据.
Ground fissure is a unique geological disaster in Xi＇an City. Taking the frame structure of the foundationbeam as the research object,and based on finite element software SAP2000,the displacement loading method is usedto simulate the uneven settlement of ground fissures. Internal force analysis of the top side of the structure and theframe structure of the bottom frame and frame column is carried out. Through the analysis of the impacts on theperformance of the foundation beam of the upper frame structure in the crack of underground,the frame structuresdesign basis in fissure field of underground.
