ANALYSIS OF ANTI-SEISMIC PERFORMANCE OF RC FRAME STRUCTURE REINFORCED WITH CFRP

A four-layer frame structure of benzene chloride workshop for Jinxi Chemical Plant reinforced with carbon fiber reinforced polymer(CFRP) is analyzed.Structure checking computations show that almost all members of the building must be reinforced except floor plate if it is used continuously as an industrial factory building.Reinforcing plan of beams and columns are presented in the design,and one of the max span beams is simulated with finite element method.The simulation shows that flexural bearing capacity of the beam reinforced by CFRP is improved effectively and the tensile stress is remarkably reduced of steel bar at bottom of beam.At the same time,the analysis of anti-seismic performance of the building by finite element simulation is completed between reinforced with and without CFRP.The simulations show that the CFRP can offer lateral resisting stiffness to reduce seismic response of the structure,and come up to seismic codes and standards.
