本文主要对GFRP加固已建的不能满足现有规范抗震规范设计要求的桥梁短柱进行试验研究。试验证明:用GFRP加固现有的剪切桥柱是及其有效的,能够大大地提高其变形性能和那里耗散能力。
Experimental Investigation of GFRP to retrofit existing circular reinforced concrete(RC)bridge columns for enhanced seismic shear strength is described in this paper. The results of this study indicated that significant improvement in ductility and energy absorption capacity.
