摘要:
基于刚性模型同步测压风洞试验结果,采用覆面积分频域计算方法,对广州松日总部大楼风荷载进行了研究。结果表明:相比顺风向而言,大楼楼层横风向振动的一致性更强; 不同风向角下顺风向与横风向基底弯矩分量组成各不相同,其与建筑立面形式相关; 大楼振动舒适度满足规范要求。通过进行等效静风荷载和峰值加速度的敏感度分析,为结构优化设计提供了指导。
Abstract:
Based on the results of synchronous dynamic pressure wind tunnel test of rigid model, the wind load of Guangzhou Songri Headquarters Building was researched in frequency domain by the way of facade wind pressure integration. The results show that cross wind vibration of floors keeps more consistently than that of downwind direction; proportions of downwind and cross wind base moment components vary with different wind direction angles and the form of a building facade; the peak accelerations of top floor in this building can meet the comfort requirements in the code. The sensitivity analysis of equivalent static wind load and peak acceleration provide guidance for the structural optimization design.
