[摘要]澳門某工程的玻璃肋幕墻系統(tǒng)采用高度均為11-6m的坐地式玻璃肋和玻璃面板。針對該超高坐地式玻璃肋幕墻系統(tǒng)進行了大風(fēng)壓作用下的結(jié)構(gòu)性能和位移能力試驗研究。研究表明,該幕墻系統(tǒng)不僅滿足3-4kPa風(fēng)壓作用下的結(jié)構(gòu)性能要求和5-1kPa大風(fēng)壓作用下結(jié)構(gòu)的安全性能要求,而且滿足三個方向位移能力的要求。充分說明此11-6m超高坐地式玻璃肋幕墻系統(tǒng)的設(shè)計方案是安全可行的,設(shè)計方案和試驗結(jié)果可為今后實際工程提供支持。

Abstract:The 11-6m high glass fin and glass panel were bottom supported in the glass fin curtain wall system of a project in Macau. 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 5-1kPa wind pressure, but also can satisfy the displacement ability in three directions. It can strongly explain that the design proposal of 11-6m height bottom supported glass fin curtain wall system is safe and feasible. The design proposal and experimental results can give adequacy support for the further use in the actual engineering.
Keywords:ultra high glass fin; curtain wall system; structural performance; displacement ability; bottom supported
