Study On The Mechanic Behavior Of T Shaped Section Column In Special-shaped RC Frame Column Structure

Special-shaped RC frame column structure system has been developed for more than two decades. In site concrete frame structure, the aseismic effect of Special-shaped frame column structure system is proved in practice. But the research in special-shaped column is not sufficient, there are still some deficiencies.This paper focuses on study in the T shaped section column and the reinforcement ratio on the overall seismic performance of structures, we can calculate the different components of column section by ANSYS finite element software, with linear and nonlinear analysis and comparison, we know the shape of column section depends not only on the location of columns, but also on the role of structure in the earthquake. T-shaped columns under the same limb length, shaped column of the seismic capacity also depends on the location and configuration of the internal steel reinforcement ratio of the size of the other key factors. Steel ratio of reinforced concrete depends not only on the level of the maximum and minimum reinforcement ratio, the seismic performance, developed a more optimized form of reinforcement ratio and reinforcement.A three-tier framework of the overall structure can be calculated and analyzed by ANSYS, according to the section of each column are the results of strain calculations, to analyze the deformation and failure mode of columns, in order to determine the structure of different section column in the effect, through the mode the output of computational structural shapes, the deformation condition of the whole structure, shaped in order to determine the framework of the seismic performance of columns.
