Nonlinear Finite Element Analysis On Seismic Performance Of T Shape Superimposed Wall Plane

Industrial mode of production must be the only way to improve the construction quality rapidly. Presently, the manufacturing technology and constructing mode of prefabricate components are improving progressively. As a result, the construction industry is being innovated thoroughly. In European countries, especially in Germany, the designing, manufacturing and later constructing of superimposed wall planes or floor slabs which included in superimposed system have been common applied. Now, this newly superimposed wall planes are introduced, the internal constructing industry must be promoted in a great degree. In Germany, it is not necessary to consider about the seismic influence on the wall plane. However, many areas in China lie on seismic area, so we must study on the wall plane’s seismic performance as we introduce it.In order to obtain the planes’comprehensive seismic performance, making use of ANSYS to analyze the superimposed planes based on forefathers’study. Bringing the constant vertical pressures and horizontal low-cycle repeated load to the T shape plane, then comparing the failure patterns, staged bearing capacity and ductility performance under different axial-pressure ratios. At last, concluding the seismic performance to be a theoretical supporting to improve the Superimposed wall plane Technology Regulation which could be widely applied in the constructing process of high-rise building.The main content of this paper listed following:(1) Carrying out simulated analysis on two type T shape planes. One of these is superimposed plane, and the other is reinforced. Simulating the concrete and link element as separated parts.(2) Bringing the earthquake-simulated load to the planes. Analyzing the results of final von mises stress distributions, crack graphics, Force-Displacement curves and comparing the staged bearing capacity, power consumption and ductility performance between the superimposed plane and reinforced plane under different axial-pressure ratios.(3) Under different axial-pressure ratios, Comparing the staged bearing capacity, ductility performance, power consumption and other mechanic capacity between the same type T shape planes. Then concluding the planes’comprehensive seismic performance.(4) Analyzing the stress-changing, failure patterns of the fabricate parts and reinforced parts. Then comparing the differences between these two parts. Searching for the contributions they separately could do to the plane’s comprehensive seismic performance.(5) Analyzing the staged bearing capacity, ductility performance and power consumption of the superimposed shear walls that use steel of different strength. Then comparing the seismic performance between these planes in different conditions.
