d类截面受压钢构件稳定承载力的分析比较

Analysis and Comparison of Stability Bearing Capacity of Steel Compression Members with Section Type d

对由厚钢板组成的钢受压构件d类截面稳定系数的正确取值进行了分析、比较,指出了钢结构设计规范GB50017-2003中受压构件d类截面稳定系数曲线确定过程中的错误;并通过按不同规范对比设计的算例,探讨了d类截面受压钢构件在不同规范之间稳定承载力的差异。

This paper analyses and compares the correct values of stability coefficient of steel compression members with section type d consisting of heavy gauge steel plates,and points out the mistakes of steel structure design code(GB50017-2003)in determining the stability coefficient of type d sections of compression members.Through contrasting design examples in accordance with different codes,the paper also discusses the differences of stability bearing capacity of steel com-pression members with section type d between various codes.
