以往,铝幕墙在飓风中损失惨重。该文旨在量化不同类型的梁-主体连接件的性能,以防止结构发生灾难性事故。试验采用了20种强连接件,例如使用厚角钢或正确安装角钢和槽钢支架间的幕墙配件。强连接件的承载力是弱连接件的2倍。为分析强连接件对整体结构的影响,利用试验结果绘制易损性曲线,通过结构建模分析将需求变量转化为风速。通过分析模型的失效概率,量化强连接件在铝幕墙中的作用。
In the past, aluminum curtain wall in the hurricane suffered heavy losses. This article aims to quantify the performance of different types of beam-body connections to prevent catastrophic structural accidents. Twenty strong connectors were used in the test, such as thick angle bars or curtain wall fittings for the correct mounting of angle and channel brackets. The strength of a strong connection is twice that of a weak connection. In order to analyze the influence of strong connectors on the overall structure, the vulnerability curves were plotted using the test results and the demand variables were converted to wind speeds by structural modeling analysis. By analyzing the failure probability of the model, the effect of strong connectors in aluminum curtain walls is quantified.
