[提要] 輕鋼結(jié)構(gòu)在我國發(fā)展時間不長，近來其用量激增，應(yīng)用范圍日益廣泛。但設(shè)計中問題較多，型式構(gòu)造老舊，用鋼量較高等導(dǎo)致輕鋼結(jié)構(gòu)不輕，難以與鋼筋混凝土結(jié)構(gòu)競爭。為此，在謀求其改進(jìn)方面提出下列討論與建議：采用高效鋼材與薄板；應(yīng)用新的設(shè)計理論與結(jié)構(gòu)型式；引進(jìn)預(yù)應(yīng)力新技術(shù)等。
[關(guān)鍵詞] 輕鋼結(jié)構(gòu) 熱軋型材 封閉截面 用鋼量 預(yù)應(yīng)力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.
Keywords: light steel structures; hot-rolled profiles; closed section; steel consumption; prestressed structure
