ABSTRACT

Masonry-infilled walls as architectural elements of a typical frame structure can be found as interior and exterior walls in reinforced concrete and steelframed structures. They are mostly considered as non-structural elements, and their presence is often ignored by structural engineers. Infill walls are often neglected in the analysis of building structures (Bare RC frame) because of their complex nature and also the absence of a realistic analytical model. Ignoring the effect of the infill in stiffening and strengthening the surrounding frame is not always a conservative approach, especially in seismic design. Different analytical models had been used considering experimental results to simulate the behavior of infill walls.
