T-shaped Cross-section Steel Reinforced Concrete Columns Finite Element Analysis Of Static

High level or high-rise building makes the bottom column suffer increasing pressure. If reinforced concrete column is still used, this will result in very large size of column section. The situations not only affect the functions of use, but also appear against earthquake of short column. Therefore, the ordinary shaped column of reinforced concrete has been very difficult to meet the requirements. To this end, a new structure was raised which was called steel reinforced concrete column. This proposed structure is conducive to solve the problems described earlier, but research is being still in its initial stage, not widely used in practical engineering. Therefore, it is imperative to study the mechanical properties.This paper adopts the original experiments of specimen size and material mechanics index, finite element analysis software ANSYS analysis different steel ratio of T-shaped section steel reinforced concrete special-shaped columns axial pressure and one-way small bias, two-way small bias loads of mechanical properties. Through analysis, obtained all specimens of ultimate bearing capacity and compared with the experimental data analysis, intercepting the destructive shape charts and specimens fracture development diagram that draws specimen force-displace ment curve and specimens, sections and steel reinforced concrete materials of stress-strain curve, detailed analysis of the destructive mechanism and specimens of each composition material force situation.Using original experiments related parameters of the test specimens then change the long fine specimen axial compressive load mechanical properties of finite element simulation analysis. Studied mechanical properties of all specimens and slenderness ratios between the relationship, and through the analysis of the specimen longitudinal displacement load curve clear the specimen longitudinal stiffness and the relationship between slenderness ratios. In addition, the author extracted from different long thin compare-test pieces of fracture development schemes, analyze the different long thin compare-test pieces with the load increasing, the transverse and longitudinal cracks in the law of development.Finally, the application of MATLAB language preparation numerical computation procedure to calculate T-shaped section steel reinforced concrete special-shaped columns limit bearing capacity and bending moment, and the obtained bearing capacity were analyzed. The results show that the two methods of specimen obtained the ultimate bearing capacity of good agreement, which validated the correctness of programming calculation and the feasibility of the method. By using numerical calculation program changes steel ratio, load Angle, eccentricity and concrete strength parameters such as analysis of these parameters, the change of the ultimate bearing capacity of specimen influence law.
