Short shear wall length and width ratio of the cross section of the pier shear walls of 5-8 , the mechanical properties of light of certain cross-section in the form of short - leg shear wall is very asymmetric , such as the cross-section of the L-shaped short pier shear wall of force to withstand loads of different directions , carrying capacity , ductility , stiffness and other properties will be asymmetric . Consider suitable steel embedded in its cross-section , by force performance will be improved , reducing the cross-sectional dimensions of components , increase the usable area of the building , and to improve the seismic performance . Therefore , the steel reinforced concrete short shear wall has broad prospects for development . This paper : (1) According to the characteristics of the residential development of the system and the short leg walls , combined with short shear wall of concrete and steel reinforced concrete shear walls of the status quo , based on the mechanical characteristics of steel reinforced concrete short shear wall Select the nonlinear constitutive relations of concrete and reinforced . ( 2) This selection of ANSYS as a tool , select the appropriate type of unit , constitutive relations and failure criteria on the basis of a number of components of the finite element analysis , analog component failure process theory reveals a steel reinforced concrete L the working mechanism of the form of short - leg shear wall , failure modes and ultimate bearing capacity . ( 3 ) the use of the finite element method of axial compression ratio , the aspect ratio of the pier , the amount of steel reinforced with steel three factors affecting the finite element test simulation , finite element analysis of this article relates to axial compression ratio of 0.1 , 0.2 and 0.3 , pier aspect ratio of 5, 6, 7 and 8 , the amount of steel reinforced with steel 4000mm2 5000mm2 , 6000mm2 and 7000mm2, finite element nonlinear analysis , draw the load - displacement curve of the specimen cracks and stress cloud , revealing the influence of the influencing factors on the short limb of the L-shaped steel reinforced concrete shear wall . Nonlinear finite element analysis (4 ) , respectively, of the L-shaped configuration section steel before and after the short shear wall specimens and compared its force performance of different specimens ; divided into four groups of specimens finite element simulation test demonstrate the reasonableness of this paper, steel with steel .
