The Seismic Safety Appraisal And Strengthening Transformation Of Primary And Secondary School Teaching Building

Brick structure collapsed or been severely damaged in the earthquake is a common phenomenon that frequently appear in the earthquake of2008, and10-year earthquake in Yushu. After the earthquake in Wenchuan, our country carry out a comprehensive investigation and identification of primary and secondary schools on the quality of housing. The quality of the investigation and identification results show that over800million square meters of primary and secondary schools to reach safety and quality standards, the need for the transformation of seismic strengthening of the seismic reinforcement of how daunting the task can be imaginedResult show that in the primary and secondary schools to conduct research census the brick structure accounted for more than90%of the entire structure of primary and secondary schools in the province, most of which are not considered earthquake fortification. The reliability of detection and identification without seismic design of brick and concrete structure, and then make the appropriate Seismic RetrofittingThe calculation and analysis of the simulation project through JDJG software that works seismic qualification, calculate the engineering floor seismic capacity index, and checking of the seismic capacity of the project. Compared the building resistance and load effects than in the unreinforced and reinforced, eventually come to select the appropriate reinforcement method based on the identification results, and verify that the selected reinforcement method ultimately improve the seismic behavior of the building...
