| 摘 要： | 应用我国钢结构规范对折线形钢箱柱进行设计,特别是局部稳定设计时存在较大的不确定性。该文利用ANSYS软件对影响折线形钢箱柱极限承载力的因素进行数值建模分析,主要研究了壁板宽厚比B/t和构件端弯矩M对极限承载力及其破坏模式的影响,对折线形钢箱柱乃至其他复杂空间结构的设计提供了有益的建议。

| Abstract: | When using China's steel structure specification for the design of broken-line steel box columns,especially for the design of local stability,there exists the large uncertainty.Here,the ANSYS software is used to make the numerical modeling and analysis for the influencing factors of ultimate bearing capacity of the broken-line steel box columns.The impacts of the width-thickness ratio of wall B/t and the end moment of component M on the ultimate bearing capacity and its failure modes are mainly studied and analyzed,so as to provide useful suggestions for the design of broken-line steel box columns and even other complex spatial structures. |
