摘要
本文对国贸中心综合体T2主塔楼进行现有周边建筑和未来规划建筑两种情况的高频天平测力试验(HFFB),分析它在两种不同周边建筑情况下的等效静风荷载及风振响应。结果表明,未来规划建筑的建造使得结构风荷载或大于或小于仅考虑现有周边建筑时,两种周边建筑情况下结构顶层加速度峰值均满足JGJ 3-2010关于办公建筑的人体舒适度要求。
High frequency base balance test of Guomao Center complex T2 building is introduced in this paper.The test consider the existing surrounding buildings and the future surrounding buildings,wind load and wind-induced response of the building is researched in two different conditions.Research results show that,compared with the structure wind load of existing surrounding buildings HFFB test,the structure wind load of the future surrounding buildings can be high and small,the top story acceleration in two different test meet the requirement of JGJ 3-2010.
