SEISMIC BEHAVIOR OF RC COLUMNS WITH VARIOUS TIE CONFIGURATIONS

To expedite the fabrication of reinforcement cages of columns, a new configuration of transverse reinforcement with alternate ties for columns is proposed. To evaluate the effect of such a configuration on the seismic performance of the column, nine reinforced concrete columns with a cross section of 400-by-400 mm were tested. Except for the transverse reinforcement, all columns were designed according to the seismic provisions of the American Concrete Institute. The tie configuration and axial load were the two main parameters investigated in the experimental program. Test results revealed that the proposed configuration of transverse reinforcement provides comparable or improved seismic performance in terms of member ductility and energy dissipation capacity to those usually used in design, and that the requirement for compression lap splice in the ties is also adequate when the proposed alternate configuration of transverse reinforcement is used.
