摘要
对点支式玻璃幕墙两端固支支撑结构和不落地支撑结构的风振系数取值问题进行了研究。在两端简支模型风振系数计算表格的基础上,加以支承方式修正和底部高度修正,由此得到适用范围更为广泛的幕墙支撑结构风振系数计算公式。数值仿真算例验证了该方法的有效性。
The calculation of the gust response factor of the point-supporting curtain wall＇s supporting structures which are fixed-supported and not on the ground, is analyzed. Based on the computing tables of former studies, differently-supported revise and over-ground-base revise are developed for wider application. Numerical examples show the veracity of this method.
