Effects of Infills in the Seismic Performance of an RC Factory Building in Pakistan

Infilled reinforced concrete (IRC) frames are a very common construction typology, not only in developing countries such as Pakistan but also southern Europe and Western countries, due to their ease of less technical skills required for the construction. Their performance during past earthquakes has been some cases satisfactory other inadequate. Significant effort made among researchers improve performance, few have highlighted influence materials used infill walls. In building codes, infills still considered non-structural elements, both design new buildings and, sometimes, assessment existing buildings. This is mainly difficulties modeling mechanical behavior large variety typologies, which difficult categorize. Some example, Eurocode, already address walls design, there lack homogeneity different codes. For code (PBC) does infills, despite being technique country. Past earthquake survey records show that types significantly affect seismic response buildings, thus highlighting importance investigating parameters. object this work, where numerical model introduced, aims at predicting failure mode, function essential parameters, friction coefficient between mortar brick surface strength, usually disregarded previous models. A comprehensive case study presented three-story IRC frame located city Mirpur, Pakistan, hit by an magnitude 5.9 on 24 September 2019. The results obtained from good agreement with damage patterns observed situ, correctly when seismically designing or assessing Pakistani make use technology.
