冷弯薄壁型钢C型构件轴压受力机理

摘要

Steel structure is more widely used with the development of steel output and technique level. And the cold-formed is a important kind of steel. Cold-formed steel specimens are quite different from the hot-rolled steel members, especially the destroy mechanism under bending-shear load. Base on this, the mechanism of C-section specimen is researched by using FEM.%随着我国钢材产量的不断提高以及技术水平的不断进步,钢结构的应用越来越广泛,薄壁轻型钢结构是目前钢结构房屋发展的主要趋势之一.冷弯薄壁型钢构件在受力上与传统热轧钢结构构件有着很大的不同,尤其是在轴压和剪弯荷载作用下的机理存在的较大的差异.在此基础上,本文针对冷弯薄壁型钢C型构件弯剪受力机理展开分析,运用有限元软件进行数值验证.
