Abstract: Seismic damage characteristics of masonry-concrete structure dwellings were analyzed according to the seismic damage investigation data of 28 sampling points in different seismic intensity regions in Lushan Earthquake. First of all, the areas of buildings with different damage grades were investigated in different seismic intensity regions and the destruction ratio of masonry-concrete structure dwellings was presented. Then, seismic damage characteristics of masonry-concrete structure dwellings were summarized and the typical damage patterns of masonry-concrete structure dwellings were given in different intensity regions. The major problems in seismic design and construction of masonry-concrete structure dwellings in the seismic region were pointed out, and the serious consequences caused by these defects were illustrated with typical structural damage examples. Finally, the seismic performances of masonry-concrete structure dwellings built before and after the Wenchuan Earthquake were compared, which shows that seismic measures of latter dwellings were better than those of the former ones. The seismic performances of latter dwelling have been obviously improved.
Keywords: Lushan earthquake; masonry-concrete structure; dwelling; seismic damage characteristic; damage grade
