【摘要】 根据温特有效截面半经验计算公式，在对腹板极限工作状态两点假设的基础上推导出了薄壁压型钢板在弯矩作用下的极限承载力的计算公式。用该式所得的计算结果与试验结果比较接近，且计算结果略低于试验结果。这种计算方法比较简单，便于使用。更多还原

【Abstract】 According to winters semi-empirical formulan for effective section and twoassumptions about ultimate state of web plale,this paper derived ultimate strength equationof cold-formed steel sheeting under moment. The equation considered post-buckling strengthof flanges and web plates simutaneously. The computing results corresponded well with thetest and were slightly smaller than ones of the test,and this method is simple and convenientfor use.更多还原
