摘要
基于计算流体力学(CFD)的风荷载数值模拟技术已较为成熟,而抗风揭试验是目前较为常用的针对金属屋面抗风性能评估的方法。鉴于既有建筑存在设计及技术资料缺失的情况,以深圳市民中心为例,提出了一种将风荷载数值模拟的结果用于既有金属屋面抗风揭试验的验证和对比,以实现对抗风性能进行有效评估的方法。经过研究分析和对比,获得了不满足承载力要求的金属屋面范围,从而为后续加固处理提供了有效的依据,验证了方法的可靠性。
The wind load numerical simulation technology based on computational fluid dynamics(CFD)has been more mature,and the wind uplift experiment is a commonly used method to evaluate the wind resistance performance of metal roof.Taking Shenzhen Citizen Center as an example,this paper presents a method to verify and compare the results of wind load numerical simulation with the wind uplift experiment of existing metal roof,so as to realize the effective evaluation of wind resistance performance.Through research,analysis and comparison,the range of metal roof which does not meet the requirements of bearing capacity is obtained,which provides an effective basis for subsequent reinforcement treatment and verifies the reliability of the method.
