Abstract
This paper takes a comprehensive building in Guiyang City,Guizhou province as the research object,preliminarily proposes four seismic reinforcement schemes,comprehensive safety,economy and load-bearing performance,and determines that the final reinforcement scheme of the existing multi-storey building is reinforced with carbon fiber composite material.After reinforcement,it can be seen that the An-gle of beam and column is>25 rad,the surface moisture content of concrete is 4.6%,the effective bonding area of carbon fiber cloth is 98%,the bonding strength of carbon fiber cloth and beam is 2.9 MPa,the bonding strength of carbon fiber cloth and column is 3.2 MPa,and the Angle thickness of carbon fiber is about 1.5 mm,all of which meet the requirements of the design specification.The reinforcement effect is good.关键词
