| Abstract: | This paper is a research on the structure reconstruction of a old school building.Through the calculation and analysis of the structure,using the prestressed reinforcement method,the negative support moment of frame beam is reduced,and sticking steel to improve the sagging moment of frame beam;adding angle steel along the columns to solve the problem of the right section'flexural capacity,jointing hooped steel plate to improve shear capacity.Seismic performance of reinforced buildings has been significantly... |
