The Research Of Swing Filler Wall Structure System Damping Performance And Design Method

With the infilled wall frame structure as an important form of building structures, the seismic design at home and abroad, and there is no uniform design standards, this has to do with this kind of structure under horizontal load is the transfer mechanism and failure mode of complex. In code for seismic design of buildings GB50011-2010 made clear that the structures of building structures, mainly including non-bearing wall should undertake aseismatic design [1], the emergence of the provision that the design of the filler wall cause enough attention. Serious earthquake damage happened several times in recent years shows that with infilled wall frame structure in the seismic design causes of unexpected damage, so it is necessary to further study. According to the seismic design of filler wall, this paper based on the former research about the infilled wall, and combined with shear wall in the design of the energy dissipation mechanism of "swing", put forward the concept of "swing filling wall".Swaying in order to study the interaction of filling wall and frame mechanism and design method, this paper mainly do the following three parts:1, by using the finite element simulation technology, framework- wall analysis model is established, under the condition of different open hole wall bottom analysis structure in the elastic stage of wall stress model, find the exact location of the open hole and open hole area of effect on the bearing capacity and ductility of frame.2, compare with build by laying bricks or stones swaying infilled wall frame and infilled wall frame structure framework of internal force distribution of elastic stage,under horizontal load, and make the load displacement curve, the ultimate bearing capacity analysis, yield bearing capacity and elastic stiffness.3, put forward swing infilled wall frame truss model, provide reference for this new design method of aseismic walls.
