摘要
Abstract
The finite element software ABAQUS was used to simulate cold-formed thin-walled C-section members with complex lips and complex lipped members with flange stiffeners under pure bending.The failure modes and flexural bearing capacities of these members under pure bending were simulated.The relationships between the failure modes,flexural bearing capacities and cross-sectional geometric parameters were analyzed,and the influence laws of cross-sectional parameters on the failure modes and flexural bearing capacities of the members were obtained.By analyzing the flexural bearing capacities of the members before and after stiffen-ing,the effect of stiffeners on improving the bearing capacity of the members was determined.关键词
