Abstract


The feasibility of this paper bonded steel reinforcement single structure system were studied seismic performance under repeated horizontal loads , the theoretical analysis for the method and determine the amount of reinforcement , the reinforcement method described theoretically . In order to investigate the feasibility of the method of the reinforcement and concrete reinforcement construction method for reinforced concrete frame structure contrast pilot study , which is a ordinary reinforced concrete comparison framework , another bonded steel reinforcement earthquake damage frame structure . Based on the test data , draw the displacement of the whole structure . The reaction force skeleton curve , the overall structure of the hysteresis curve , steel reinforced load - strain curve , stiffness degradation curve . Binding the test phenomena and test curve Comparative analysis reinforcement structure and contrast structural resistance in the structure of the external loads , the stiffness degradation changes, the deformation of the system , the changes carried out by the cracks , by the force of the entire specimen process detailed description and analysis ; and reinforced the destruction of the state of the structure , the change of the stress and strain to make accurate descriptions and reasonable explanation . Visible through test data analysis , this reinforcement can be established to improve the structure of the overall carrying capacity , effectively improve the bearing capacity , stiffness and ductility of the structure , to achieve the purpose of the trial is expected reinforcement . Model using the ABAQUS finite element analysis software to establish two specimens , and nonlinear analysis will analyze the results with the experimental data , the theoretical analysis results were compared , after analysis of the experimental values ??and simulation agree well . Reinforcement effect of its advantages such reinforcement approach through research and analysis , summarize the experience in the testing process , and to lay the foundation for the application of the actual reinforcement works .
