| 摘 要： | 根据Salvadori公式,提出一种新的计算H型钢梁在不等端弯矩作用下的侧扭屈曲临界弯矩值的公式,通过有限元ABAQUS和ANSYS两种软件进行模拟并与提出的公式进行对比,对比结果良好,说明该公式建立的正确性。为了进一步验证公式的适用性,文中还将该公式与各国规范公式进行了对比分析,对比结果吻合良好,由此得出该公式对实际的工程有指导作用。

| Abstract: | According to the analysis about Salvadori formula,a new formula about the critical buckling bending moment was put forward when the H shape steel beam are under unequal end moments in this paper.Through the comparative analysis between finite element software ANSYS and ABAQUS and the formula,it shows that they are matching good,and for the further prove that the new formula is correct.In order to test the applicability of the formula,the formula was compared with the different countries such as Europe,the United States and national code,and so on.To our surprised,the contrast results was matching good.At last,it is proved that they have higher engineering application value. |
