In order to analyze the mechanical properties of the remaining carrying capacity of steel reinforced concrete columns after exposure to fire, full preparations must be needed. In this paper, the numerical simulation of the temperature field of steel reinforced concrete column section was being adopted the finite element analysis software MSC.MARC to analyze. Temperature distribution law of the column cross-section in the case of uneven fire was obtained. There has a nice agreement between calculation and original test data which created the conditions for high temperature and high temperature performance analysis for SRC columns

To overcome disadvantages of usual Cast-In-Place (CIP) concrete pile methods in top-down construction, some prototypes of a joint of the PHC pile to column that directly connects a column to a PHC pile are analytically studied. With the consideration of strength requirement and stress concentration of joint of the PHC pile to column, we suggest the most appropriate one.

Making use of the numerical analysis method, the ductility of reinforced concrete column with Z-shaped cross-section was analyzed. Considering stirrup confinements’ influence upon concrete deformation, with using self-made programs, some elements imposing influence on column section ductility were analyzed, such as axial compressive ratio、loading angle、material strength and setting mode of reinforcing bars. The results indicates that the loading angle has great influence on section especially under smaller compressive ratio, while the strength changes of the concrete and reinforced bars has a little influence. Thus, without changing amount of steel, encrypted hooping will effectively improve the ductility of column section.

The steel reinforced concrete column is one of the important members for structures, it is essential to study the high temperature performance of concrete column. The numerical simulation research is done using finite element software ANSYS. Under the high temperature, the analysis of the compressive bearing capacity and flexural capacity of the concrete columns strengthened by CFRP is done, and the compressive bearing capacities of different cross-section concrete columns strengthened with CFRP are tested.
