点接式玻璃幕墙超强度分析

摘要

The stress fields of bolted glass curtain wall under wind load were studied by means of finite element method and the features of the stress states round holes in bolted glass were discussed. Comparing the results of calculation by means of finite element method with experimental data, the reasons that glass plates in bolted glass curtain wall under wind load were used in the state of"super strength"were explained.%采用有限元方法计算了点接式玻璃幕墙在风荷载作用下的应力场，并讨论了孔边应力特性.将计算结果与实验结果相比较后发现，通常认为的玻璃板"超强度"使用只是根据计算结果所得的结论，实际使用情况与此差别较大.
