| Abstract: | The shear mechanism of RC bridge columns under strong earthquake ground movement is discussed in the paper.The concept of residual shear strength in the plastic hinge zone of RC bridge columns under strong earthquake ground movement is proposed.Based on review of current code expressions of major seismic countries.improvements for current code on shear design of RC bridge columns under strong earthquake ground movement are suggested. |
