超高坐地式玻璃肋幕墙系统结构性能和位移能力试验研究

Experimental investigation on structural performance and displacement ability of ultra high bottom supported glass fin curtain wall system

澳门某工程的玻璃肋幕墙系统采用高度均为11.6m的坐地式玻璃肋和玻璃面板。针对该超高坐地式玻璃肋幕墙系统进行了大风压作用下的结构性能和位移能力试验研究。研究表明,该幕墙系统不仅满足3.4kPa风压作用下的结构性能要求和5.1kPa大风压作用下结构的安全性能要求,而且满足三个方向位移能力的要求。充分说明此11.6m超高坐地式玻璃肋幕墙系统的设计方案是安全可行的,设计方案和试验结果可为今后实际工程提供支持。

The 11.6m high glass fin and glass panel were bottom supported in the glass fin curtain wall system of a project in Macao.The experiments investigation on structural performance and displacement ability of the ultra high bottom supported glass fin curtain wall system were carried out.The test results show that the curtain wall system not only can meet the structural performance requirement under 3.4kPa wind pressure and the structural safety requirement under 5.lkPa wind pressure,but also can satisfy the displacement ability in three directions.It can strongly explain that the design proposal of 11.6 m height bottom supported glass fin curtain wall system is safe and feasible.The design proposal and experimental resuhs can give adequacy support for the further use in the actual engineering.
