The Experimental Study And Non-linear FEM Analysis Of Superimposed Slab Shear Walls

At the present,the residential construction is in the stage of persistent unprecedented development,and is becoming the new economic growth point. With the improvement of the speed of urbanization, more and more high-rise residential was built. Based on the traditional shear wall, a new shear wall structure system- the superimposed slab shear wall was advanced in this paper. The shear walls not only have the good capability of resisting earthquake; but also overcome the shortcomings of traditional shear wall, such as the long cycle and large moulding board..The test was done with three shear walls by horizontal low frequency cyclic loadings in this paper .The whole destroy process was observed. At the same time, the load-displacement hysteresis loops were obtained. Through the test data, their properties including strength property, deformation property and energy property was studied. Speaking in detail, we studied the cracking load, the yield load, the failure load, recovery force model, stiffness degradation, dissipative coefficient and the property of ductility.Based on the experiment, combining the test means and FEM value theory together, a non-linear finite element analysis was carried to three walls with ANSYS. Through comparing and analyzing of the bearing capacity, the development of crack and the stress-strain curves, the results showed that the load-deflection curves for specimens from the finite element analysis agreed well with the experimental data. If choosing rational constitutive behavior, ANSYS program could simulate the test process well.
