| 摘 要： | 基于ANSYS对某轻钢框架结构示范住宅楼建立了有限元模型,在风荷载作用下分别按一阶方法、二阶规范方法、二阶有限元方法计算了底层柱底弯矩与顶层柱顶侧移,对数据进行了比较分析,同时对二阶效应下柱底弯矩随风荷载增大的变化规律进行了研究,此外还进行了3D模型下二阶效应的计算和分析并与2D模型进行了比较,其结果令人满意。

| Abstract: | In this article, the second-order effect of a multi-story residential building in light steel is analyzed and calculated with considering wind effect. The result of second-order effect is analyzed with the comparison of the Code method and FEA method. The result of comparison is satisfied. It's verified that the method of the Code for design of steel structures is accuracy. At the meanwhile, the FEA is another availability way. There is a suggestion, that more attention should be put into the column bottom moment in the first floor for its addition ratio of second-order effect is huge. |
