THE ASEISMATIC REINFORCING DESIGN OF A VOCATIONAL SCHOOL’S MASONRY DORMITORY

This paper introduces a six-story brick students dormitory of a vocational school,the original earthquake fortification intensity was 6 degrees,fortification category was C-class.After the Wenchuan earthquake,the fortification intensity of Deyang was raised to 7 degrees,the classfication for earthquake-resistance of middleschool buildings became B-class.The project concluded with seismic inspection report,the seismic calculation results and the requests of the measures for 8-degree earthquake-resistant construction,which used these reinforcements:adding tie columns at the junction of interior and exterior wall,steel grid mortar surface to reinforce the wall,adding fine aggregate concrete lamination layer on the precast slabs.These reinforcement programs can strengthen the integrity of the structure,enhance the ductility of the wall,and improve the aseismatic performance of the building.
