This thesis is to experimentally investigate seismic behavior of steel reinforced concrete (SRC) columns subjected to constant axial load combined cyclically lateral loading. Ten large-scale specimens which included 5 traditional SRC columns (TSRC) and 5 new SRC columns (NSRC) were tested. The parameters studied in this test comprised: the required transverse steel bars for NSRC and TSRC when bending about x-axis and y-axis for seismic design; effectiveness of composite actuation plate (CAP) inserted in plastic hinge region; effectiveness of longitudinal flanges and effectiveness of bf/tf ratio; and the different seismic behavior between NSRC and TSRC columns.
Test resulted showed that: (1) the required transverse steel bars from ACI and TW-SRC is too conservative for SRC columns; (2) the specimens with the amount of transverse steel bars, which is based on the design concept used in this study, exhibited satisfactory behavior; (3) the CAP had effect in enhancing strength ratio and displacement ductility for the specimen; and (4) using wider flange width, using XH section instead of H section for steel shape, and using NSRC instead of TSRC can achieve better seismic performance
