摘要
介绍了"东方之门"建筑的动态测力试验的方法和结果,并通过测点风压系数积分程序计算得到整体的平均风荷载,与风洞天平测力的结果进行比较,发现两者之间吻合得比较好。分析了邻近建筑和群楼干扰时,在某些风向角下出现的比较明显的"遮挡效应"和"狭管现象"。
The method and the result of dynamic pressure measure in ＂the door of east＂ building are introduced.We obtained the contour of its surface wind pressure and write a program which can use the metrical wind pressure coefficient to compute the mean wind load of the whole building.Here comparing with the result of balance,we find the two results accord with each other.In some wind angle evident cover effect and gorge effect appeared in analyzing the interference effect of wind loads of a cluster of buildings.
