Seismic Performance Experimental Research on Reiforced Concrete Columns Strengthened with CFRP

Abstract eng:
CFRP has a light weight, high tensile strength, and a high resistance to the corrosion and fatigue. These properties make CFRP attracted increasing interests in civil engineering. Based on shaking table tests of several reinforced concrete (RC) flat slab beamless construction models, the seismic performance of square columns strengthened with carbon fiber reinforced polymer (CFRP) composites are investigated. The effects of CFRP quantity and load types to seismic behavior of RC square columns are studied. According to the test results and Italian-Chinese approaches of FRP-based strategies tailored for seismic retrofitting, one or more calculated methods or opinions will be provided. In the future, with the cooperation activated between the Harbin Institute of Engineering Mechanics and the University of Roma “La Sapienza”, finite element dynamic analysis will be carried out by OpenSees, and approximate agreement between test and theoretical results will be achieved.
