隐框玻璃幕墙地震反应分析
|
摘要
本文对隐框玻璃幕墙的地震反应进行了一系列计算分析 ,并采用了考虑隐框玻璃幕墙与承重结构动力相互作用的整体有限元分析方法。针对不同工程结构模型 ,分别分析了对地震作用于幕墙平面内、平面外的情况 ,找出了影响幕墙地震反应的主要参数及特点。文中指出 ,必须涉及承重结构与幕墙的共同工作 ,根据分析结果对现行规范抗震分析方法进行了讨论。
In this paper, a series of calculations were carried out for the earthquake response analysis of concealed frame glass curtain wall.The integrated finite element method is used considering the dynamic interaction of concealed frame glass curtain wall and the load-bearing structure. In accordance with different engineering structure models, the earthquake actions are analyzed both in and out of the plane of curtain wall.The main parameters and characteristic for the earthquake response of curtain wall were found. It is indicated that the mutual work of load?bearing struture and curtain wall must be involved. From the results of analysis, the earthquake analysis method in the current seismic design code is discussed.
