摘要
分别采用简单公式和有限元法计算了MIC_1 2 0金属拱型波纹屋面的临界载荷 ,分析了金属拱型波纹屋面稳定性 ,并且和拱型波纹屋面临界载荷的试验结果进行了对比 ,着重分析了MIC_1 2 0金属拱型波纹屋面面外失稳问题 .理论分析和试验结果吻合 .研究结果表明 ,拱型屋面的破坏不是强度不足 。
This paper uses simple equations and finite elemetn method to calculate the critial load of the MIC-120 metal arched ripple roof.It analyses the stability of the metal arched ripple roof by comparing it with the experiment conclusion of the metal arched ripple roof,particularly analyses the lost stabilization problem of the MIC-120 metal arched ripple roof:its theory agrees with its experiment.It is shown that the breakadge of arched roof is due to its stabilization loss,instead of less strongth.
