Experimental Study On The Frame Structure Reinforced By The Adhesive Steel Plate

This paper researched a anti-seismic reinforcement method to single bulding system with adhesive steel plate by load-on repetitive load, then did some corresponding theoretical analysis to determine the reinforcement amount, and then confirmed the availability of this reinforcement method with theoretical explanation. Meanwhile, in order to study the availability of this method and the construction way, this paper did some comparative experiments to the reinforced concrete frame, one is the common reinforced concrete frame, the other is the reinforced concrete damaged frame with the adhesive steel plate.Based on the test data,the thesis drew the whole structure's displacement-reaction skeleton curve,the structure's hysteresis curves,steel pipe and the reinforing steel's load-strain curve and the structure's stiffness degradation curve. It also combined the experimental phenomena and the tests'curves,and gave some comparative mechanical properties analysis between the reinforced structure and the correlation structure,such as the structure's loads resistance,stiffness degradation,the system's deformation,and the cracks.And then the paper made some detailed descriptions and analysis to the whole process of the specimen's force changings. In the end,it made an accurate description and a reasonable explanation to the reinforced structure's breakage and the changes in stress and strain.The experimental data analysis shows that using this reinforcement can improve the buildings'carrying capacity. After the reinforcement,the structure's bearing capacity,stiffness and the ductility has been improved and achieved the purposes of expected reinforcement have been achieved.The auther used ABAQUS finite element analysis software to establish the models of two specimens, and gave some non-linear analysis, then made some comparisons to the analytical result, experimental data, and the theoretical analysis results, through the analysis, we found that the experimental data and simulation values were in good agreement. In the end,the advantages of this reinforcement method are analyzed and the experience which was got in the experiment was concluded as well, and a foundation to the Practical reinforcement engineering was laid firally.
