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.

Nice Agreement

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

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.

Hysteretic Characteristics

The study on the hysteretic characteristics of steel reinforced concrete (SRC) members is the basis of nonlinear seismic analysis of such structures. So in this paper, by summarizing the hysteretic features of SRC members, a quadrant-linear restoring-force model is suggested. Then the model is verified with available experimental results and proved to be effective and reliable.
