【摘要】 轻钢结构房屋已被广泛应用,但是设计中有些问题尚需进一步讨论.本文针对采用压型钢板等轻型板材的屋盖中,设置在轻钢檩条上翼缘和下翼缘的拉条的布置和作用提出个人看法;指出一些设计参考书, 对文献[1]式(附3.2-2)中 a 取值的错误,并给出了 a 的正确取值;建议采用文献[5]相应的计算式,计算在檩条有效受风面积>10m~2时的风荷载体形系数.并针对上述问题给出算例.更多还原

【Abstract】 The buildings of light-weight steel structure are widely applied,but some problems of the design need to be disc(?)ssed.This paper proposes some personal opinions about installation and position of tension bracings on top flange and the bottom flange of the light-weight steel parlins on the roofs that use light-gauge plate such as profiled steel sheets pointed out in certain design reference books and the right value of a in the appendix formula (3.2-2) of Reference [1] is provided.It is proposed that the formule in Reference[5] should be used to calculate shape coefficient of wind load when the effective area is less than ten square me- tres.Some calculation examples are provided.更多还原
