虽然相关设计规范中已给出了方形高层建筑风荷载和风振响应的经验计算公式，但角隅修正处理对方形高层建筑风荷载和风振响应的影响尚需定量评估。本文首先对一个基准方形高层建筑和三个角形修正方形高层建筑进行了风压测量，获得了风压的时空变化规律。在ANSYS软件中建立了相应的足尺有限元模型，分析了其动力特性。结合风洞试验结果和模态分析，对4栋方形高层建筑的风荷载和风振响应进行了计算和比较，以设计出减小方形高层建筑风效应的最佳气动处理方案。本文旨在为方形高层建筑的结构设计者和业主提供风效应消减的直观对比。
Although empirical formulas have been provided in relevant design code for estimating wind loads and wind-induced responses on square high-rise buildings, the effects of corner modification treatments on wind loads and wind-induced responses of square high-rise buildings need to be evaluated quantitatively. In this study, wind pressure measurements for a benchmark square high-rise building and three corner modified square high-rise buildings were first carried out to acquire the spatial-temporal varying pressure distributions. Moreover, the corresponding full-scale finite element models were established in ANSYS software to get their dynamic properties. Combined with wind tunnel test results and modal analysis, wind loads and wind-induced responses of the four square high-rise buildings were calculated and compared for designing the best aerodynamic treatment of reducing wind effects on square high-rise buildings. This article aims to provide visual comparisons of wind effect reduction for structural designers and owners of square high-rise buildings.
