Nonlinear Numerical Analysis of SRC-RC Transfer Columns

Abstract:

SRC-RC transfer columns are commonly designed as a transition floor for high-rising buildings to transfer from lower SRC columns to upper RC columns. The mechanical performances are studied in the paper using the finite element software of ABAQUS. Nonlinear numerical analyses are made for SRC-RC transfer columns firstly to obtain the relationship between force and displacement at top of the columns. By comparing the analytical results with experimental ones, it is found that the results from finite element analysis coincide well with experimental ones. So ABAQUS software could be used as a supplementary means to simulate SRC-RC transfer columns mechanical behavior. Then the factors such as steel ratio and axial compression ratio are contrastively analyzed. The results show that axial compression ratio has a greater influence on the bearing capacity and hysteretic performance of the structure, but the steel ratio has less influence. Finally, comparisons between SRC-RC and RC columns are also made to demonstrate the mechanical performance of SRC-RC columns further. Conclusions drawn in the study might be useful in practical engineering design.
