Özet

The seismic capacity and response of unreinforced infill walls have been ignored until realizing the importance of these members during many seismic events and their aftermaths. The performed study aims to obtain seismic behavior of infill walls in the out-of-plane direction. Fort this, an experimental study including 8 infill wall tests was conducted. The out-of-plane capacity of the unreinforced masonry infill walls with different opening sizes were investigated by using two different infill materials; clay brick blocks, and pumice concrete blocks. The presence and the size of the openings were chosen as the test parameters in addition to the infill materials. The infill walls with window opening, door opening and without opening were simulated by using a half-scaled RC frame. Additionally, lintels were used for each infill walls with opening. After conducting 8 unreinforced infill wall specimens which include 5 clay brick infill walls and 3 pumice concrete infill walls under out-of-plane loading it was noticed that the infill walls with the door openings had the least load carrying capacity while the window opening simulated infill walls have the highest load carrying capacity for both infill materials under out-of-plane loading. Moreover, it was observed that the construction direction of the clay brick blocks affects the load carrying capacity in the out of plane direction. Another observation is that the infill wall specimens with pumice concrete have higher load carrying capacity than the infill wall specimens with the traditional clay bricks for all kind of infill walls.
