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 the curtain wall is tested for wind pressure resistance, the measured deflection data are analyzed and compared with the calculated values in order to accurately determine the deflection and safety of the larger sub-insulating glass. In this paper, it is considered that it is not appropriate to study the deflection change simply by a linear function, and it should be judged whether the measured deflection and the safety performance under the standard value of wind load (Wk, corresponding to P3) meet the requirements of the test standard. Based on this, Appropriate revisions to the existing testing standards for determination of wind pressure resistance.
