摘　　要：城市既有建筑屋顶安装风力发电机受到越来越多人的关注。只有对屋顶风场特性有清楚了解,进而考虑风力发电机安装后对下部结构的影响,才能确定安装风力发电机是否可行。以某公司办公楼东南栋屋顶安装风力发电机为实例,并根据相关风向、风速监测和计算流体动力学(CFD)对办公楼东南栋屋顶风场进行模拟,分析得出办公楼东南栋屋顶风场可以满足风力发电机的运行要求。在对风力发电机塔架进行荷载分析后,通过PKPM软件将荷载施加于房屋结构上,对办公楼整体结构安全进行分析。研究可为城市既有建筑屋顶垂直轴风力发电机的安装提供参考。The installation of wind turbines on the roofs of existing urban buildings has garnered increasing attention.Feasibility can only be determined through a clear understanding of the characteristics of the roof wind field and an assessment of the impact of the wind turbine installation on the substructure.This study takes the installation of a wind turbine on the southeastern roof of a company office building as an example.Based on relevant wind direction and wind speed monitoring and Computational Fluid Dynamics(CFD)simulations of the wind field on the southeastern roof of the office building,it is concluded that the wind field on the southeastern roof of the office building meets the operational requirements of a wind turbine.After conducting a load analysis of the wind turbine tower,the loads are applied to the building structure using PKPM software to analyze the overall structural safety of the office building.This research provides a reference for the installation of vertical axis wind turbines on the roofs of existing urban buildings.
