对深圳湾体育中心进行了测压试验、风环境试验和风振响应分析。着重研究了屋盖悬挑部分上、下表面脉动风压的相关性,指出相关系数对合压力脉动强度有重要影响。并通过对比测压试验,评估了周边建筑对屋盖平均风压和脉动风压分布的影响。周边建筑的存在使得平均风压幅值降低,而脉动风压明显增大。根据风环境试验结果,分析了体育场内部风场的分布,对当地主导风向进行评价,并提出针对性建议。最后,基于同步测压试验结果,对屋盖结构进行了基于时程方法的风致响应计算,得到了动力风荷载作用下的位移响应特征。
Shenzhen Bay Sports Center conducted a pressure test, wind environment test and wind vibration response analysis. The correlation between the fluctuating wind pressure on the upper and lower surfaces of the overhanging part of the roof was emphatically studied, and the correlation coefficient was found to have an important influence on the combined pressure fluctuation intensity. By comparing the pressure measurement test, the influence of the surrounding buildings on the roof average wind pressure and the fluctuating wind pressure distribution was evaluated. The existence of the surrounding buildings makes the average wind pressure amplitude decreases, while the pulsating wind pressure increased significantly. According to the results of the wind environment test, the distribution of the wind field inside the stadium is analyzed, and the local dominant wind direction is evaluated. Relevant suggestions are put forward. Finally, based on the results of synchronous manometry test, the wind-induced response of roof structure based on time-history method is calculated and the displacement response characteristics of dynamic wind load are obtained.
