To promote the application and development of light gauge steel framed residential dwellings in our country , the research on structural performance of light gauge steel framing should be enhanced and the structural system according with architectural system should be developed 為推動輕鋼龍骨住宅在我國的應用和發(fā)展,必須加強對輕鋼龍骨結(jié)構(gòu)性能的研究,開發(fā)出配套的低、多層輕鋼龍骨住宅結(jié)構(gòu)體系。
Concerning the tests , analyses , design and calculation of performances for light gauge steel framing , this paper focuses on following items : ( 1 ) the calculation of light gauge steel framed compound bearing walls ( lgsfcbw ) in compression and bending . based on north american specification and commentary for the design of cold - formed steel structural members , which was published by the american iron and steel institute , the detailed design requirements of wall stud assemblies are given considering the structural contribution of the attached sheathings and shear diaphragm is discussed briefly . then the calculational theoretic and method for sheathing braced wall stud assemblies complying with national code is brought up in compression and bending 本文圍繞輕鋼龍骨體系結(jié)構(gòu)性能的試驗、分析、設計和計算,主要進行了以下四方面的研究工作: ( 1 )輕鋼龍骨復合承載墻體的受壓、受彎計算:以美國鋼鐵協(xié)會發(fā)行的北美冷成型鋼構(gòu)件設計規(guī)范及其規(guī)范說明為依據(jù),重點考慮罩面材料對墻龍骨設計的影響,給出了目前對承重墻龍骨設計的具體要求,并對剪力蒙皮進行了簡要討論;然后提出了符合我國規(guī)范術語的剪力蒙皮作用的輕鋼龍骨復合承載墻體(即罩面支撐墻龍骨)受壓、受彎的計算理論和方法;最后對提出的計算進行簡化,使之完全與我國規(guī)范相符。
