Change the structure of system reinforcement is to reduce the original the load and improve the safety margin of the structure as a whole, by changing the original structure of the stress system. Structural system reinforcement is currently focused on the framework and masonry structures.We found that there are certain problems and security risks in the structural design by detection and identification and structure of the overall dynamic characteristics test on a frame structure teaching building. We adopt the existing frame structure to frame-shear wall structure system reinforcement method to ensure the teaching building safety and improve the structure system problems. New shear wall structure is the first seismic fortification line, to further improve the seismic safety of the structure.The reinforcement design selected based primarily on the results of the detection and identification of the original structure. This article reflects the quality of construction structure and present situation by physical strength of concrete, component size deviation and deformation, the vertical deviation of overall structure, member reinforcement condition and the thickness of the protective layer and concrete crack. This paper reflects that there are Shortcomings and defects in the structure design or not, by means of check the original structural design. Design defects caused cracks on the basis of the entity test results and design check results. And it is found that the structure period ratio slants big phenomenon in the structural design, so adopted the overall dynamic characteristics test of the structure, the test results show that the structure of the existing torsion structure stiffness problem.We finally adopted the change the structure of the system reinforced method-the original frame structure system to the frame-shear wall structure system. In order to obtain better economic and time-efficient, PKPM structure design software was used to the new shear wall quantity, location and length of the design variables optimization design in this paper. The best in terms of security and economic reinforcement to optimize the design was selected according to Optimal Design.Using ANSYS finite element analysis software to the Unreinforced and reinforced teaching building structure the design simulation. And accurately analyze of the structural reinforcement of the original structure. Increase the stiffness of the original structure, significantly reduced the layer displacement and maximum displacement, improve the design flaws of the original structure of the tensional rigidity of the defects and structural layout is unreasonable, and improve the overall seismic capacity of the structure, that shows that the method is feasible, especially for primary and secondary schools and other key fortification of engineering. |
