[提要]  幕墙的铝合金立柱、横梁并非脆性材料，在计算这些构件的风荷载时是否也应考虑“阵风系数 β_z= 2.25”？连接立柱与主体结构的固定支座是否也要做成“弹性活动连接”？作者就此及幕墙设计中的其它一些问题提出个人看法。

The columns and beams extruded from aluminum alloy used in glass curtain wall are not of brittle material. The personal opinion has been presented about some problems in glass curtain wall design, such as, if the factor of gust β_z=2.25 should be considered in calculating the wind load of the construction, if the static support connecting the curtain wall columns with the main structure should be designed as elastic movable connection, etc..
