It comprised reinforced concrete structure, masonry structure, bottom frame structure, industrial workshop. The buildings were designed by the different periods of Code for Seismic Design of Buildings. The seismic fortification intensity of the most buildings was seventh degree, the other was eighth degree. As the great seismic intensity of Yingxiu town, the buildings were destroyed most seriously. The engineering damage of the buildings was characteristic. The earthquake provides a lot of valuable information for the seismological investigation。The research of engineering damage is important to the investigation on theory and engineering.
