Research Of Masonry Structure Seismic Appraisal And Strengthening Of Primary And Secondary Schools

Our country is a country of more earthquakes, Primary and secondary schoolbuilding mostly is masonry structure, Because of the limitations on its seismiccapability and building its own characteristics determine its in the past suffered seriousdamage in the earthquake. What is more, Some buildings without reasonable design,Structural system chaos, Ring beam, reduction is not set or set unreasonable, Cutcorners in the construction process, Poor quality causes increased damage, causedserious losses to the country.This article through to multi-storey masonry structure phenomenon of earthquakedamage investigation and analysis, This paper introduces the contents of test andevaluation of specific process, is an object with a specific engineering example, find outthe weak parts of the project on its reinforcement, for strengthening the construction inaccordance with the comprehensive seismic capacity evaluation and PKPM seismicstrengthening method to analyze seismic performance specified in the section. Thenaccording to the problems existing in the engineering, how to through the relevanttechnical means in the process of construction to be prevented, then, from theconstruction of the easy degree, security, engineering cost, impact on the environmentand so on several aspects has carried on the evaluation after reinforcement, Finallyexplores the window under the failure mode of the wall and through the windowbetween the wall reinforcement conditions of proposed wall under the window first,This condition is put forward in the masonry structure wall between windows as thepillars of the frame structure, below the window wall as a beam frame structure. according to the framework of the structure of the related ideas, introduction ofstrong column weak beam of the ductile fracture theory, got the structure of ductilefracture inequality. and construction to conform to the calculation of earthquake damagehas occurred, found that it is reasonable. fill the blank of seismic code. At the sametime, some structural measures to set multichannel seismic line for masonry structure,make it up to destroy the orderly, form a gradual process of ductile fracture，avoidbuilding suddenly collapsed，the teachers and students in sensation to win the time toescape.
