摘要
应用ANSYS有限元程序,分别对直卷边和斜卷边C形和Z形截面冷弯型钢受弯构件的畸变屈曲性能进行研究。对比发现,多数直卷边构件的抗弯承载力略高于斜卷边的,在相同截面参数条件下,C形和Z形截面的抗弯承载力相差很小。计算结果还与直接强度法进行了对比,结果发现,多数构件的计算结果高于直接强度法的结果。
The distortional buckling performance of cold-formed C and Z section flexural members with upright and inclined edge stiffeners has been studied by finite element program of ANSYS. The results show that most of the bending strength of members with upright edge stiffeners is slightly higher than that of members with inclined edge stiffeners. And the bending strength of C and Z section members almost the same when the section parameters are the same. Comparison of the computed results with the results of direct strength method shows that most of the computed results are higher than that of direct strength method.
