Totally 6 models marked A1-A6 were chosen from affected region in Wenchuan earthquake, and the other 6 models marked B1-B6 were fictitious unconfined masonry structures having the same configuration and other characteristics as A1 to A6 except for in confinement details. Totally 20 accelerograms were collected on different soil conditions in Wenchuan earthquake were selected as input accelerations. The study focuses on two aspects: seismic response comparison between the numerical analysis results and the observations from the earthquake investigation; and the response of the confined structures and the unconfined structures to the same inputting PGA. It implied that the ductility of confined masonry buildings was significantly improved and anti-collapse capacity was enhanced comparing with the unconfined ones.
