1 前言钢—砼组合柱是钢砼组合结构的重要基本构件,在本文中利用微机对砼包双槽钢组合柱进行了分析,其可作为试验研究的辅助工具来验证试验结果,也可用来建立规范中的图表为工程设计提供方便。利用微机对组合柱进行全过程分析,首先从建立组合截面的弯矩—曲率关系开始,然后根据弯矩—曲率关系利用数值积分法,建立荷载—挠度关系曲线,曲线的峰值就是极限荷载。
1 INTRODUCTION The steel-tantalum combination column is an important basic component of the steel truss composite structure. In this paper, a computer is used to analyze the double channel steel composite column, which can be used as an auxiliary tool for experimental research to verify the test results. It can also be used to Establish the chart in the specification to facilitate the engineering design. Using a microcomputer to analyze the whole process of the assembled column, we first start by establishing the moment-curvature relationship of the combined section, and then use the numerical integration method to establish a load-deflection curve based on the moment-curvature relationship. The peak value of the curve is the ultimate load.
