Abstract (EN): The investigation of collisions between contiguous building structures due to severe earthquakes is of great importance, particularly in large cities where there is a high population density. These collisions will produce strong impact forces that will significantly influence the dynamic behavior of building structures. Moreover, these impacts may provoke serious structural damage, that can lead to local collapse, or in the worst-case scenario to complete structural collapse. Different measures and techniques in mitigating pounding effects between adjacent buildings during seismic hazard events were extensively developed and studied by several researchers in recent years. This study presents an overview of these different pounding mitigation solutions, namely regarding the required separation seismic gap, link elements, shock absorber devices, structure stiffening, and supplemental energy and control devices. The main conclusions of several researches, from pioneer to state-of-the-art studies, concerning code provisions for minimum gap sizes and solutions for pounding mitigation between buildings, are compiled and presented in this study to demonstrate its diversity, effectiveness, and practical applications. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2021.
