摘要：

Progressive collapse in a building has caused local damage, so it spreads across the system and causes large-scale collapse of the entire building. Progressive collapse is usually due to fire, gas explosion, terrorist attack, vehicle collisions, and misplaced design and construction. Therefore, it is necessary to study and investigate the effect of this phenomenon on structures and to rebuild the building against it. In recent years, much research has been conducted on the effect of infills against progressive collapse, but, in this study, the effect of all types of infill performance is investigated and which infills has best performance against progressive collapse. In this research, we examined and evaluated some proposed solutions in technical literature for four simple frame modes and considering the intermediate brick conditions, as well as the use of a plate and wall of a 3D panel and their comparison. In the present study, a five-story frame using two-dimensional Opensees software is retrofitted using the above techniques, and the results show that it reduces vertical displacement and also improves the re-distribution of forces. © 2019, Springer Nature Switzerland AG.
