| In recent years, China’s urbanization process develops in a rapid speed.And more people move to the city from the countryside, which brought thehousing problem. The problem cannot be handled without combing with thedevelopment of the modern industry. Semi-precast superimposed slab shearwall system, as a kind of structure which is adapted to industrial production,could meet the sustainable development of the environment. This structurehas the obvious characteristics of fast construction speed, high quality, lesspollution, less using of wood template etc. Such structure was a introductionof technology from German, expanding the applicability of research in theunique site conditions and construction environment in China is to promotethe use of the foundation. Supported by National Science Foundation(No：50908071), this paper studied the seismic performance of semi-precastsuperimposed slab shear wall system by simulation and experiment.To evaluate seismic performance of the semi-precast reinforcedconcrete (RC) shear wall structure, two full-scale I-shaped sectionspecimens which consist of the perpendicular walls and the T-shaped edgeelements, four slices of superimposed slab shear walls and two general shearwalls were tested under cyclic reversed loads by our team. This paperfocuses on the two full-scale I-shaped section specimens, the structuralfailure feature, stiffness, ductility, hysteresis property, energy dissipationwere analyzed systematically, and nonlinear finite element analysis of thetwo shear walls was carried by CANNY program. The simulation resultswere compared with the test result. At last, two slices of superimposed slabshear wall with different edge restricted form, and the I-shaped section shearwall with T-shaped edge restricted form were compared to find out how thestructure performance under seismic with different forms of edge restricted. |
