摘要
通过大型通用有限元程序ANSYS对波形钢腹板抗剪性能进行仿真分析,分析结果表明,当局部区域的剪应力达到了屈曲强度的槡1/3时,则腹板进入塑性,部分区域将出现局部屈曲现象。波形钢腹板剪应力等值线基本平行于腹板高度方向,剪应力沿高度方向均匀分布,这点对于设计中控制剪切屈曲破坏有一定的指导意义。
Through Large - scale General Finite Element Program ANSYS shear performance of corrugate steel reaches the of bucking strength, web, the analysis result shows that, when then webs enter into plasticity, local phenomenon. The isoline of corrugate steel web shearing strength is parallel to shearing strength is uniform distributed along the height direction, which have controlling the shearing bucking damage during the design. to conduct the simulated analysis on the shearing strength of local region region will emerge local bucking web height direction basically, and some certain guiding significance for
