Load Tests

The low-cycle repeated load tests were conducted for two composite frames, with reinforced concrete column and steel reinforced concrete column, respectively. The performance of the composite frames such as the failure modes, ductility, energy dissipation ability, deformation restored ability, and resistant capacity is analyzed. Experimental results show that good seismic performance can be obtained by appropriate constructional measure which can meet the seismic design requirements. Based on the analysis of test data, the reliability of the beam-to-column connections is validated, and the seismic performance of composite frames is found to be influenced mainly by vertical anti-lateral force component. Besides, the form of steel reinforced concrete column is recommended to improve the structural ductility.

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

Concrete Pile

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.
