高大模板支撑系统构件重要性分析OA北大核心CSCDCSTPCD

This paper is based on the engineering background of high-supported formwork in a building,using element add or remove,taking the first mode of eigenvalue analysis as the initial geometrical imperfections to analyze ultimate bearing capacity,then the importance coefficients of different kind of components can be got,after that some theoretical analysis of vertical bars is done,the results show that the importance coefficient of vertical bracing is the highest,and the buckling load of vertical bar is increased along the corner vertical bar,side vertical bar and inter-nal vertical bar.
