以上海世博会后的世博博物馆“欢庆之云”复杂形体大跨度新建工程为背景对象,运用数值模拟方法,研究在不同风向角来风且存在周边建筑风场干扰的情形下,表面曲率多变的多连体大跨空间建筑结构的表面风压、阵风系数和等效静风荷载.对风压云图和分区域风压系数进行了分析,并基于峰值因子法求解阵风系数,进而提出了考虑最不利风向角的等效静风荷载. Taking the new project of “Splendid Cloud” and complex shape of Expo Museum after Shanghai World Expo as the background object, the numerical simulation method is used to study the influence of the curvature of the surface Surface wind pressure, gust coefficient and equivalent static wind load in the multi-span and multi-span long-span space building structure.The wind pressure cloud chart and sub-regional wind pressure coefficient are analyzed and the gust factor is solved based on the peak factor method, Equivalent static wind load considering the most adverse wind direction angle.
