摘要
无锡新区科技交流中心外观造型新颖独特,屋盖为梅花形金属曲面,四周为弧形玻璃幕墙。结合结构和围护系统的抗风设计要求,制作了1∶150刚性模型进行风洞试验研究,重点考虑了周边高层建筑的气动干扰作用,论文对比了周边有无高层建筑两种工况下的风压分布情况,并且将建筑表面划分为31块,分析了高层建筑对分块风压的影响情况。试验研究结果为主体结构、金属屋盖和玻璃幕墙提供设计依据。
The shape of Wuxi New District Science Technology Communication Center（STCC） is novel and special： roofing with plum blossom-shaped metal curved surface,surrounding by arc glass curtain wall.For the requirements of wind resistance design for the structure and surfacing system,a rigid model with 1：150 scale was made,and the wind tunnel test was carried out to study the distribution of wind pressure about two work states： with and without high-rise buildings around the STCC,focusing on the aero-interference action of nearby high-rise buildings.The building surface is divided into 31 regions and the regional wind pressure is analyzed considering the effect of the high-rise buildings.The test results are summarized to conduct the design of main structure,metal roof and glass curtain wall.
