金属拱形波纹屋盖受力特性及倒塌分析

摘要

The stressed processes of the arched corrugated metal roof with large span under all-span uniformly distributed, semi-span uniformly distributed and all-span triangular loads were simulated by the finite element softwear of ANSYS, and the stressed characters was analyzed to confirm the weak location in the roof. The collapsed causes of the arched corrugated metal roof in engineering incident were analyzed, and the improving measures were suggested too.%利用有限元软件ANSYS对大跨金属拱形波纹屋盖在全跨均布荷载、半跨均布荷载和全跨三角形荷载这三种不同荷载形式作用下的屋盖受力过程进行数值模拟,分析其受力特点,确定屋盖受力的薄弱环节,对金属拱形波纹屋盖在工程中出现倒塌事故的原因进行分析,并提出了改进措施。
