建筑物滑动迁移中托架的优化分析

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。

ANALYSIS OF THE OPTIMIZATION OF UNDERPINNING FRAME IN BUILDING RELOCATION BY SLIDING

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.
