Damage Analysis And Reinforcement Of Masonry Classroom Building

May12,2008, occurred in the wenchuan earthquake, is another huge earthquake Since Tangshan earthquake damage.Caused a large number of casualties and huge economic losses.As Mediterranean and Pacific two large belt junction area, Our country hase been a relatively serious earthquake country. Greater level of earthquake will cause serious building damage and casualties. Due to the use of dense crowds and poor oself-protection ability of the users, making Primary and secondary school is a special one of the affected buildings. Therefore, raising on the importance of primary and secondary teaching building, strengthening primary and secondary school teaching building seismic safety measures are most important in today’s society。 In varying degrees in the earthquake damage, after strengthening, but can continue to use part of the school building, and we need to take effective measures to strengthen their capacities for earthquake prevention and disaster reduction, which is something we should continue to study the current and the future direction of debelopment. Thro development.Through the study on seismic technologies and earthquake strengthening technology of primary and secondary schools, teaching building of the school eventually becomes worthy of school teachers and students and nearby residents "first asylum".This paper to middle and primary school teaching building damage vestigation and study as the basic work, the author summarizes the typical earthquake resistance problems existed in various weak links of primary and middle school buildings and carefully investigates its manifestations and analyzes the causes of earthquake damage, so that it can provide some beneficial information for the earthquake resistance strengthening work of school buildings in order to adapt to the current science and technology society.After comprehensively analyzing reasons for the existing building reinforcement and its press force characteristics after reinforced, introduce the reinforcement principle of the masonry structure; deeply discuss the reinforcement ways that are used frequently in the masonry structure; generally introduce the cement grout in approach, buttress column strengthening steel-mesh cement mortar strengthening, construction structure strengthening and point out the construct and calculate main points of all kinds of strengthening ways. Integrate some foregoing theories, take the connected building of the kindergarten for example, briefly analyze the process of appraisal and the design and construction of reinforcement are used in projects.The skills of construction column strengthening and the surface of the steel-mesh cement strengthening have the ability to enhance the entirety of masonry structure and seismic performance.
