摘要
轻钢结构在我国发展时间不长 ,近来其用量激增 ,应用范围日益广泛。但设计中问题较多 ,型式构造老旧 ,用钢量较高等导致轻钢结构不轻 ,难以与钢筋混凝土结构竞争。为此 ,在谋求其改进方面提出下列讨论与建议 :采用高效钢材与薄板 ;应用新的设计理论与结构型式 ;引进预应力新技术等。
The time of development of light steel structure in our country is not so long.At present,its amount and area of application increase day by day.But there are many problems in the structural design,such as the old types of structural detail,the high steel consumption and so on.Hence,it is difficult to compete with reinforced concrete structures because of higher steel consumption.This paper discusses and proposes the following improvements:application of high effective steel material and thin plates;adoption of new design theory and structural forms;utiliztion of prestressed technique.
