建筑幕墙结构风荷载最小取值分析

Analysis of the Minimum Value of Wind Load for Curtain Wall Structure

深入介绍了幕墙结构的安全保证,并进行了幕墙结构的风荷载取值分析。建筑幕墙的风荷载取值,应考虑地面粗糙度按阵风荷载计算取值,而不应规定最小值。可以借鉴高层建筑对风荷载的处理方法,设计幕墙结构承载能力并进行变形计算,但应考虑加强幕墙构件的节点连接,即节点连接设计时考虑反力增大系数,从而达到既安全又经济的双重效果。

The authors introduce safety assurance for curtain wall structure,and analyze wind load value of curtain wall structure.The gust load for ground roughness should be considered for wind load value of curtain wall structure,the minimum value of wind load should not be regulated.The bearing capacity and deformation of curtain wall structure can be designed by using experience of wind load processing method of tall building for reference,but joint connection strengthening curtain wall components should be considered,that is to say,amplifying coefficient of reaction should be considered when joint connection is designed,which is a safe and economic method.
