| 摘 要： | 本文剖析了现行规范玻璃幕墙地震作用的计算公式，指出其不足，用结构抗震的振型分解反应谱理论，建立了物理意义明确，考虑建筑场地和主体结构动力特性影响，适用于单、多自由度主体结构幕墙地震作用的计算公式，算例表明：荷载效应减小达４４％。本文结果改进了规范地震作用的计算方法，可直接用于工程实际，也可用于其它材料的幕墙。

| Abstract: | In this paper,the present code calculating formulas of earthquake action on glass cladding are analysed,and the defects are pointed out ;the calculating formulas of earthquake action on glass cladding which are of the clear physical meaning,consider the influence of buildng site and dynamic characteristics of main structure,and are suited for the main structure of single or multiple degree of freedom system are established by using the theory of modal decomposition response spectrum of aseismic structure.The calculating example demonstrates that the effect of load is reduced to 44%.These results improve the calculating method of earthquke action and can be directly applied to the practice of engineering and the claddings made of other materials. |
