ANALYSIS OF THE OPTIMIZATION OF UNDERPINNING FRAME IN BUILDING RELOCATION BY SLIDING
-
摘要: 为探究建筑物滑动迁移方式中合理的托架设计形式,采用ANSYS软件对某框架结构建筑物建模,对比分析了8种不同形式的托架对迁移建筑物变形及受力的影响,同时优化了托架斜撑的截面尺寸,进而给出了一种较为合理的托架结构。结果表明:托架6具有变形小、受力状态良好、结构简单的特点,推荐作为优先采用形式;在合理形变量范围和安全强度内,托架斜撑截面尺寸大小可减小为原来的50%,且变形与受力状态良好。Abstract: To explore the reasonable form of underpinning frame in the building relocation by sliding,ANSYS software was used to build a model of frame structure building moved by sliding,and then compared impact of eight different forms of underpinning frame on building deformation and stress while optimizing section dimension of diagonal bracing,thus a more reasonable underpinning frame was given.The results showed that the underpinning frame 6 had characteristics of small deformation,good stress state and simple structure,which was recommended to be the first available underpinning frame form.Optimized the section size of bracing could be reduced to 50% of its original size within the selected reasonable displacement and safe stress,while the deformation and stress state were perfect.
