Experimental Study on the Seismic Behaviors of HRBF400 RC Columns

CODEN: JTEVAB

Abstract

In order to investigate the seismic behaviors of RC columns reinforced with HRBF400 steel bar (HRBF-high strength hot rolled bars of fine grains), four rectangle cross-section HRBF400 RC columns' bending low-cycle reversed loading experiments were made. Influences of reinforcement ratio, axial compression ratio, and stirrup ratio on the seismic behaviors of HRBF400 RC columns were analyzed. Characteristic of hysteretic curve and skeleton curve are studied, and characteristic value and displacement ductility of each specimen was calculated. The results show HRBF400 RC columns have good seismic behavior. Yield load, peak load, and ductility improve with the increasing of reinforcement ratio. Columns of high compression ratio have high peak load and yield load, but their skeleton curves decrease quickly after peak load and have low ductility. Columns of low compression ratio have low peak load and yield load, but decrease gentlly after peak load and also have good ductility. Seismic behaviors and ductility of RC columns improve with the increasing of stirrup ratio.
