Wind damages of the curtain wall have been occured on both high rise buildings and low rise buildings. The main causes of these phenomena seem to be non-existence of the clearness of wind pressure mechanism. which applied on curtain wall. The object of this project study is to pursue the curtain wall which has high performance to wind load.Following procedures are taken : 1) The wind damages of sash, window glass and shutter were investigated by field work. And moreover, the construction methods of these curtain wall were collected. 2) The low rise house(2.7mx3.6m plan. 3.1m in height) were erected and equipped wind pressure sensor. displacement meter on the curtain wall. The reference wind speed and wind direction were measured at 4m in heightapart 10m wind ward from the observation house. The records of wind speed and wind direction of the reference point, wind pressure data acting on the curtain wall and its deformation and displacement under relatively strong natural wind were obtained and were recorded by data recorder. 3) These data were analyzed by use of the statistical method. The characteristics of the wind force and the response of the curtain wall were investigated. The model of the wind forces were introduced based on the experimental results.

高层建筑和低层建筑都有幕墙的风害。造成这些现象的主要原因是风压机理不明确。应用于幕墙。本课题的研究目标是寻求具有良好抗风性能的幕墙，具体工作如下：1）通过现场调查，研究了窗扇、窗玻璃和百叶窗的风害。并对这些幕墙的施工方法进行了总结。2)低层住宅（2.7mx3.6m平面图。3.1米高），并配备风压传感器。幕墙上的位移计。参考风速和风向是在距观测室10m迎风面4m处测量的。通过数据记录仪记录了基准点的风速、风向、作用在幕墙上的风压数据以及在较强自然风作用下幕墙的变形和位移。3)用统计学方法对这些数据进行了分析。研究了风荷载的作用特性和幕墙的响应。根据试验结果，提出了风力模型。
