Design Criteria of Wind Load Applied on Curtain Wall

无论是高层建筑还是低层建筑，都曾发生过幕墙的风害。造成这些现象的主要原因似乎是没有明确的风压机制。适用于幕墙。本课题的研究目的是寻求对风荷载具有较高性能的幕墙，主要采取了以下步骤：1)现场调查了窗扇、窗玻璃和百叶窗的风害情况。此外，还收集了这些幕墙的施工方法。2)低层房屋(2.7mx3.6平方米)。3.1米高)，并安装了风压传感器。幕墙上的位移计。参考风速和风向是在距观测室10米高的风区4米处测量的。获得了基准点的风速、风向、作用在幕墙上的风压数据以及在较强的自然风作用下的变形和位移的记录，并用数据记录仪进行了记录。3)采用统计学方法对数据进行分析。研究了幕墙的风力特性和响应特性。在试验结果的基础上，给出了风力模型。

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.
