Abstract:
This paper reports loading tests conducted to investigate the effect of tri-directional seismic force on the shear capacity of reinforced concrete (RC) shear walls. The experimental parameters were the magnitude of out-of-plane deformation and axial load condition. All specimens reached the in-plane maximum load capacity at approximately Rx = 0.50%. The maximum value of the average shear stress divided by the tensile strength of concrete decreased by 12.1 to 18.2% with increasing difference between axial compressive force and tensile force. The minimum safety margin was 1.07 attained for the specimen subjected to out-of-plane lateral load and varying axial load acting simultaneously, while that of the specimen subjected to only in-plane lateral load under constant axial load was 1.50. The safety margin was defined as the ratio of the maximum load capacity obtained experimentally to the calculated capacity.
