Theoretical Analysis And Experimental Study On The Structure Of New Type Of Shear Wall

In recent years, because of arrangement about fa?ade and plane of our high-rise buildings, the growing complexity of the structure and structural height and seismic intensity increasingly, which cause that the traditional categories of high-rise buildings lateral force resisting system can not meet the normal requirements. Therefore, in order to solve this problem, searching for a new lateral force resisting system has become a focus of attention in engineering.By means of finite element numerical simulation analysis software ANSYS 14.0 and large low-cycle pseudo-dynamic test(MTS), analysis of static, material nonlinear, elastic dynamic time history and engineering test main to a new staggered shear wall lateral force resisting system in this paper. Static analysis is mainly to study the mechanism of the new force structure of shear walls under the two types of horizontal loads. And, compared to the redistributions of internal forces of traditional(double limb) wall structure, which summarizes extent of the merits about the overall mechanical performance between the new structure and the traditional structure.In aspects of the ultimate bearing capacity, ultimate displacement, crack development, overall lateral stiffness and stiffness degradation, structural shear, displacement time history curve,interlayer displacement angle, analysis of material nonlinear and elastic dynamic time history mainly compares with the two types of structures,. Meanwhile, in order to verify accuracy of the theoretical results, after carrying out horizontal low cyclic loading pseudo-dynamic test for a shear wall specimens of staggered structures, then, the test results of the overall structure compares to the theoretical results of ANSYS 14.0 by the failure modes, hysteresis curve, displacement ductility, stiffness degradation and other aspects.Based on theoretical analysis and experimental study of staggered shear wall structure, for the sake of providing a design basis for engineering application of this new structure, proposing some structural measures to improve the mechanical performance of the overall structure of the force for framework of beams, columns, shear walls and node, where appears intensive cracks, according to the current "Code for design of concrete structure", "Technical specification for concrete structures of tall building" and "Code for seismic design of buildings".
