Critical Load of Glass Fins in the Glass Curtain Wall Systems

建立了全玻幕墙玻璃肋失稳临界荷载的解析式。以三边简支板为分析模型,运用能量法,推导得到了玻璃肋受面内荷载作用时发生失稳的临界荷载解析式。将该解析式计算所得到的临界荷载与ANSYS分析的结果进行比较。结果表明,解析式计算的结果是可靠的,该解析式是准确的,给玻璃肋失稳临界荷载的求解提供了参考。

In this paper a formula for critical load of glass fins in the glass curtain wall is established. The formula is based on an analytical model involving a plate with three simply supported edges which is under a uniaxial asymmetrical distributed compressive pressure. The results which are gotten from the expression are compared with which are gotten from the analysis with the FEA -ANSYS. The results show that the expression is effective and tried, which provides a reference for the calculation of critical load of the glass fin .
