Experimental study on seismic performance of RC short columns strengthened with BFRP and CFRP

Abstract:

Low cyclic loading test is conducted on one comparative short column and five RC short columns strengthened with BFRP and CFRP. The tests shows that failure modes, shear strength, ductility and energy dissipation are improved and increased for specimens strengthened with BFRP. In the same condition, various short columns strengthened with BFRP and CFRP give similar seismic performance. But BFRP has a good perspective for its low cost and good comprehensive mechanical properties in seismic strengthening field.
