Studying several parameters on unreinforced masonry infill walls R.C framed structure by SeismoStruct program

Reinforced concrete infilled-frames (IF) are commonly used in buildings in the world nowadays. They are often built schools, offices, dwellings, and hospitals, and other kinds of residential and public buildings. The infilled is generally considered a nonstructural element and is ignored in design and analysis despite his strong interaction with the bounding RC frame. Unreinforced Masonry infill walls (URM) are commonly used in the Reinforced Concrete (RC) framed structures as interiors and exterior partition walls. In this research, the behavior of infilled frames is inspected through studying eight frame models were studying several parameters on unreinforced masonry infill walls R.C framed structure such as bare frame (BF), infilled-frame (IF), infill panel with different compressive strength and infill panel with different thickness. Verification studies are performed on one previous experimental works through nonlinear pushover analysis. The analysis showed that increase compressive strength of infill panel increase capacity and thickness of infill panel increase capacity.
