Non-linear Finite Element Analysis On The T-shaped Short-leg Shear Wall Of Reinforced Concrete Structure

With rapid development of civil construction, there are some new structure systems that are some well beneficial result structure in economy. As a new structure system, the short-leg walls system has the characters of both frame-structure and shear-wall structure, but it also has some new characters of its own. So far, most of the studies and experiments of this newly developed structure system are carried out on the whole structure. Few works are conducted on members level. This paper argues that it is the adoption of the new anti-literal force members that results in the specific behaviors of the system.Because of lack of fond in research, these structure systems cannot be well used in fact. Now people are adopting the simulation test to resolve this question. And, withal, 1:1 scale specimen can be employed in simulation test that can avoid appearing the 'distortion' in the scale-down test. In simulation test, the same test can be made times without number and results of test are more full-scale and exact.Based on computer simulation theory and finite element analysis method, and the finite procedure ANSYS software, this paper the simulation test was done on T-shaped short-leg shear wall, which revealed the basic property of it. In simulation analysis, a spatial unit that has eight node and 24 degree of freedom compose finite element model, and spatial non-linear finite element analysis method is adopted to calculate.In static test, T-shaped specimen was respectively divided into four groups according to concrete strength grades, sectional height to thickness ratio, reinforcement ratio and ratio of axial compressive force to axial compressive ultimate capacity of section. How these factors affect the load-carrying and deformation of short-leg shear wall is known by analysis the result.
