摘要
在对幕墙进行抗风压性能检测时,为准确判定较大分格中空玻璃的挠度和安全性,对挠度实测数据进行了分析并与计算值进行了比较。本文认为不宜简单按照一次线性函数关系研究其挠度变化,应以其在风荷载标准值(Wk,对应P3)下的挠度实测值和安全性能是否满足检测标准的要求来判断,并据此建议,对现行检测标准之抗风压性能判定方法进行适当的修改。
When testing wind load resistance performance of curtain wall, in order to judge the frontal deflection and safety performance of the larger insulating glass, the measured value of deflection is analyzed and compared with the calculated value. It is concluded that the variation of frontal deflection could＇t be simply studied by a linear function, instead, it should be judged according to whether measured value and safety performance under wind load standard value （Wk, corresponding to P3） could match the standard or not. At last, it is suggested that the judgment of wind load resistance performance test in current standard should be revised properly.
