| 摘 要： | 采用ANSYS软件对冷弯薄壁型钢门式刚架的蒙皮效应作了探讨性研究.对比分析了无蒙皮门式刚架和有蒙皮门式刚架的顶点竖向位移与柱顶水平位移.计算结果表明,蒙皮效应对刚架整体竖向和水平位移都有很大的限制作用.设计时,可以考虑适当放松按平面刚架计算的刚架柱顶水平位移值,来考虑蒙皮效应.

| Abstract: | FEM software of ANSYS is used to analyze the diaphragms effect of cold-formed steel portal frame.The apex vertical drifts and lateral deflections at eaves of cold-formed steel portal frame considering diaphragms effect are computed,and these are compared with that without considering diaphragms effect.The results indicate that diaphragms effect can limit the apex vertical drifts and lateral deflections at eaves.The lateral deflections at eaves based on plane portal frame calculational model may be released ... |
