Light gauge steel construction whose structural framing is constitutive of cold - formed steel members has been on a rapidly increasing sacle and has been used for low residential construction widely in the world since the construction has a series of prominent advantages such as light weight , high strength and stiffness , energy saving , environmental protection , ease of prefabrication and mass production , fast and easy erection and installation and so on , but its research and application has just begun in our country 全部采用冷成型鋼構(gòu)件作為結(jié)構(gòu)受力骨架的輕鋼龍骨住宅體系具有輕質(zhì)、高強、節(jié)能、環(huán)保、施工速度快、易于產(chǎn)業(yè)化等特點,近年來在國際上發(fā)展迅速并廣泛用于低層住宅,但在我國研究和應(yīng)用還處于啟動階段。
Referring to the forms of floor solution abroad , autoclaved lightweight concrete ( alc ) floor used in low buildings and precast alc composite slab used in middle buildings are put forward . furthermore , the calculational methods and corresponding analyses are discussed . ( 4 ) research on design method of low light gauge steel constructions in north america 本文研究全工業(yè)化的輕鋼龍骨體系在低、多層住宅中的結(jié)構(gòu)性能,以結(jié)構(gòu)體系創(chuàng)新為出發(fā)點,開展一系列理論研究,并以相應(yīng)試驗來檢驗理論分析結(jié)果,對推動輕鋼龍骨體系在我國的應(yīng)用具有理論和應(yīng)用價值。
