摘要
屈曲模态在一定程度上影响了冷弯C型钢梁构件的受力性能,为了得到钢梁屈曲模态和双向弯曲之间的联系,采用ANSYS有限元软件,建立SHELl181壳单元有限元模型,对冷弯C型钢梁在双向弯曲作用下的失稳进行了分析,得到钢梁在不同角度的斜向横向力作用下的不同屈曲模态,并对双向受弯钢梁屈曲模态的一般规律进行总结。
Buckling mode affected the cold-formed channel beams in mechanical properties to a certain extent,in order to obtain the relations of buckling mode and biaxial bending,ANSYS finite element software was used to establish SHELl181 shell element finite element model. The instability of the cold-formed channel beams under biaxial bending is analyzed,besides the different buckling modes of steel beams at different angles of oblique transverse force,and the general rules of biaxial bending beam buckling modes are summarized
