摘要/Abstract

摘要： 工业建筑由于使用功能的要求，结构层高往往不均匀，楼板开孔很大，导致结构竖向和平面均不规则。结合工程实例，采用PKPM有限元计算软件，分析了层间受剪承载力比及层间位移角限值对不规则框架结构的影响。当不满足规范规定的限制时，可调整结构布置，以满足结构计算和工艺设备布置的要求。

Abstract: Due to the requirements of use functions, in one industrial building, the storey heights often are not the same, and the open pores on the floors are larger, which lead the irregularity of the structure in vertical and horizontal directions. The influences of the interstorey shear bearing capacity ratio and the limit value of the interstorey displacement angle on the irregular frame structure were analyzed combining with practical engineering project and using the PKPM finite element calculation software. When the limit value stated by relative specification can not be satisfied, it is able to adjust the structure arrangement to meet the requirement of the structure calculation and the technical equipment layout.

Key words: irregular frame structure, axial compression ratio of column, inter-storey shear bearing capacity, limit value of displacement ratio
