A single storey, full-scale unreinforced confined brick masonry building was designed, based on Standard No. 2800 of IRAN, and
constructed on the shaking table at the Earthquake Engineering Research Center, EERC, of Sharif University of Technology. The
model consisted of a vertical reinforced concrete tie column and horizontal steel bond beams and had a jack-arch roof system.
The walls had openings of different dimensions, making it possible to investigate the effects of the shape, geometry and location
of the openings. The model was subjected to some seismic experiments, consisting of scaled records of the Bam, Tabas and Elcentro earthquakes as well as harmonic acceleration with a gradually increasing amplitude. The results indicated that the proper workmanship of ties, especially the proper connection of tie columns and bond beams, plays an important role in the integrity and stability of the structure. The creep of the masonry walls and subsequent reduction in frictional resistance between the walls and steel bond beams were effective on the out-of-plane failure of the brick walls.
