| 摘 要： | 本文主要对钢屋盖与混凝土支承结构在实际设计中的问题展开讨论,根据两者不同的材料特性及受力特点进行计算分析。结果表明:矢跨比、跨度对拱脚水平推力影响均较大;对于小跨度(21m左右)时,下部支承结构采用混凝土时经济效益较好。通过对钢屋盖与混凝土柱连接处设为滑动支座,可释放一定的推力,从而对减小混凝土柱钢筋用量起到显著效果。

| Abstract: | This paper mainly discusses the questions that exist in design of steel roof and concrete supporting structure,and then has a calculation and analysis according to the different types of material properties and mechanical characteristics.The results show that:rise-span ratios and span all have a larger effect on horizontal thrust of skew back.As for small span(21 m or so),it is economic to select concrete structure for the lower supporting.Joint between the steel roof and concrete column selects the sliding bearing,which can release certain thrust,so as to reduce the dosage of reinforced concrete column. |
