冷弯薄壁型钢组合墙体抗剪性能的有限元模拟

On finite simulation of resisting shearing performance of cold-formed and thin-walled steel combination walls

对单调加载作用下冷弯薄壁型钢组合墙体进行了非线性有限元分析,考虑了材料非线性、几何非线性的影响,采用三个方向一维非线性弹簧单元模拟自攻螺钉连接,通过与试验数据对比,验证了有限元方法的正确性。

The paper has the non-linear finite elementary analysis of the cold-formed and thin-walled steel combination walls under the monotonic loading, considers the influences of the materials＇ non-linear and geometric non-linear, adopts three direction and one-dimension non-linear spring to simulate the self-drilling screws connection, and proves the correctness of the finite elementary methods by comparing the tests data.
