| 摘 要： | 在确定冷弯薄壁型简支钢梁应力-应变模型的基础上,采用有限元软件ANSYS对冷弯薄壁型简支钢梁荷载-位移关系进行非线性有限元计算分析。对冷弯薄壁型简支钢梁荷载-位移关系骨架线、弯矩-曲率关系骨架线进行比较分析,主要比较了跨高比、宽厚比对其的影响。

| Abstract: | On the base of thin-walled cold-formed steel stress-strain relationship,a nonlinear finite analysis is carried on the load versus displacement relation of thin-walled cold-formed steel simple beams by the program ANSYS.In addition,the parameters of load-displacement framework curve and moment-curvature framework curve of the thin-walled cold-formed steel simple beams were analysed on the research.And the effect of span-height and width-thickness on them is compared mainly. |
