Experimental Research On New Type Of Light-gauge Steel Composite Wall Under Vertical Loadings

Web Light-Gage steel joist structure system (Web steel) is a new type of steel structure, coming from Canada with such many advantages as higher standardizing, assigning space flexible, good performance of the seismic resistant, industrialization producing, short Construction period, protecting environment and economizing energy sources et al. This kind of structure has been used mostly in low story residential building for 20 years in North America. It agrees our national estate policy applying Web steel to multiple-story residential building. Web steel has a good future in China.Because of the existing obvious differences between the principle and methods of design and application in overseas and that in homeland, it is quite necessary for us to research the load bearing performance of this structure in theory and experiment aspect.In this paper on the basis of experiments, the vertical resistance behavior of new type of light-gauge steel composite wall is researched, and thirteen full-scale wall specimens are tested on their behavior under cycle lateral loadings. In this paper we also aspects on the problem of new type of light-gauge steel composite wall as below:(1) Experimental research of seven full-scale wall specimens under vertical loading was finished(2) Understanding destruction pattern and supporting capacity of the different types of walls in steady destruction(3) Its Influence to vertical loading capacity of wall because of the difference of connection way and cover surface's structural panels(4) Probe into model and formula of Theoretical calculations to vertical bearing capacity.
