压型钢板拱形屋盖结构山墙抗风柱的设计

On Gable Wind Truss Design of Sheet Steel Arc－ shape Roof Structure

文章指出在大跨度结构山墙抗风柱设计中，不能把薄钢截面本身视为一弹性支座，而应将抗风柱上端视为自由端，通过在抗风柱中上部设置支点，保证建筑物安全。

During design of wind truss of large－ span structures, it is pointed out that sheet steel roof surface shall not be considered as an elastic support, but the top end of wind truss shall be considered free. Additional supports shall be set at the mid＆ upper parts of wind truss for ensuring the safety of structures.
