Quality Assessment of Equivalent Strut Models for Reinforced Concrete Frames with Unreinforced Masonry Infill Walls

© 2016 Taylor & Francis Group, London. The analytical evaluation of Reinforced Concrete (RC) frames with Unreinforced Masonry (URM) infill walls under earthquake loading comprises many uncertainties and assumptions, especially for the infill walls, which might lead to a misleading interpretation and prognosis of the inherent resistance and overall response. This paper presents an extensive study on the equivalent strut method and the study focuses on determining the strut widths by means of different empirical equations available in the literature. As a case study, a masonry infilled RC frame has been considered. In particular, a sensitivity study is conducted for the different input parameters describing the strut width to indicate the variations in the global response of the infilled RC frame. By performing time history analysis and comparing the analytical with the experimental results, the most suitable strut width is determined.
