(1 Xi' an Jiaotong University, Xi' an 710049, China; 2 Slujiazhuang Tiedao Uruversity, Shijiazhuang 050043, China)Abstract: After Wenchuan earthquake, the Ministry of Education required all the uruversities to reinforce the buildings damaged in the earthquake.A gymnasium was one example of them. The gymnasium is a large-span woodem roof truss, not meeting the current standard requirements, so it was once difficult to determine the reinforcing scheme. After many times anylsis, demonstration, comparation and seismic check, in the end, we chose the reinforcing scheme of wraping the brick columns with reinforced concrete, reinforcing the walls with steel mesh, in the same time, insteaded the woodem roof truss with a new built steel roof truss. After the reinforcement and reconstruction, the gymnasium not only met the current standards, but also stregthened the anti-seismic performerce of the original structure obviously.
