摘要
采用数值方法对某高层建筑上部装饰幕墙结构进行了抗风研究。对表面风压进行了数值模拟,获得了风压分布特性;利用准定常计算方法,在频域上计算该结构的风致振动响应;然后用两种方法计算了等效静力风荷载。
Wind resistant design of a curtain wall located in the top of a super-tall building was carried out using numerical simulation technology. The wind pressure distribution on the wall was numerically simulated and discussed. Then the quasi-steady assumption was applied to construct the along-wind loading acting on the wall and furthermore the wind-induced buffeting responses were computed in frequency domain. Two methods were used to calculate the equivalent static wind loading in structural design.
