General Defects Analysis of Masonry Buildings Damaged in Wenchuan Earthquakes and Its Inspirations

Abstract eng:
General design or construction defects of masonry buildings damaged in Wenchuan 8.0magnitude earthquake, which occured on May 12, 2008, were summarized. Based on Seismic Design Code of Buildings （GB50011-2001）, some typical earthquake damages of the masonry buildings investigated on-the-spot , including buildings with irregular section planes, with unreasonable partial tectonic design, with unreasonable height-width ratio exceeding the limited value, and with uncertified material performance indexes and construction qualities, were presented. The design defects of the damaged masonry buildings in Wenchuan earthquake were analyzed, the main reasons why so many masonry buildings were severely damaged in Wenchuan earthquake were founded, which can provide valuable references for the seismic design and construction of the masonry buildings during the reconstruction of disaster areas in the future.
