- Abstract:
- Aiming at the seismic damage of reinforced concrete(RC)frame structures,and based on Perform-3D software,we adopt two reinforcement methods,carbon-fiber reinforcement and steel-bonded reinforcement to reinforce the earthquake-damaged concrete frame structures.Taking three-layer,six-layer and nine-layer RC frame structures as examples,we study the seismic fragility of RC frame structures with seismic damage and analyze their reinforcement effect based on incremental dynamic analysis(IDA).The results show that with the increase of strctrure’s height and PGA,the overall convergence of the IDA-curve clusters of the carbon-fiber and steel-bonded reinforced structures at the third,sixth,and ninth layer are better after being damaged by earthquakes.The steel-bonded reinforcement can improve the convergence of the structure to the randomness of ground motions,but with the increase of the structure’s height,the effect of steel-bonded reinforcement on the random convergence of ground motion gradually weakens,and the steel-bonded reinforcement method has obvious effect on the three-layer,low-rise structures.The carbon-fiber reinforcement has better control of the displacement angle between the structural layers than the steel-bonded reinforcement.For the six-layer,middle-rise structures,the resistance of the structure to extremely rare earthquakes can be improved to a greater extent.For the nine-layer,high-rise structures,the two reinforcement methods are practical,and we can choose one of them according to the actual situation.
