Experimental Study On The Structure System And Joint For Multi-storey Steel Residential Building

With great increasing of steel output,it provides architecture industry with ample repertory of raw and processed materials,one new pattern structural system--steel frames system house have been widely attached importance and opened out and researched.By far,the research of this system has come generally into the phase of startup.One side this new pattern is studied and practiced by the architecture industry, a lot of steel frames system houses have been made experiments and much constructive experience and technological production have been obtained;one the other hand,some desiderate undone technical problems have been found in practice.Steel frames system houses were considered as investigative object,from the two aspects of frames system and joint,through classified and investigative way, extensive is carried through in this paper.Firstly,review of the developing history about steel structure residential building, real projects and achievements in China are classified and summed up, the feasible and necessary of developing steel structure residential building in China is analyzed .Secondly,in allusion to 8 degree aseismatic area,the frame structure-supporting system and the frame structure system were contrasted,at the same time,the rationality and economy of structure system also explained by calculation.By six models,it was approved that it was more rational and economic to adopt the frame structure system compared with the frame structure-supporting for multiplayer residential building. For eight to eight-storey above residential steel building, in order to increase the rigidity of structure and fulfill the need of interlayer- horizontal displacement and total lateral sway rigidity, the frame structure-supporting system may be adopted.Thirdly, use the software ANSYS of finite element analyse, simulate and calculate the joint, analyse its resistance. The effect of different diameter of bolt and thickness of end-plate connections is analysed by nonlinear finite element , beam-column end-plate connections resistance is studied , and based on the M-θrelations of beam-column end-plate connections analyses the effect of diameter of bolt and thickness of end-plate.
