Seismic pounding between adjacent buildings: Identification of parameters, soil interaction issues and mitigation measures
https://orcid.org/0000-0002-6741-115X
Abstract Structural pounding has been observed in many previous earthquakes due to insufficient gap commonly provided between adjacent structures. The collisions usually generate large impact forces and short duration acceleration pulses which may result in significant damage to the colliding buildings. Because of that, earthquake-induced structural pounding has been intensively studied and investigated for the last three decades. Results of some of these investigations are compatible, whereas others contradict. This work reviews previous research studies concerning earthquake-induced structural pounding aiming to better understand pounding phenomenon itself and the reasons behind the contradictory results. The effect of pounding on buildings with fixed bases, isolated buildings, and buildings resting on soft soils are discussed. Then, aspects of a sufficient recommended gap are considered. Appropriate mitigation measures are also addressed and directions of the future research studies on structural pounding are recommended.
Highlights The main drawback of the present impact models is that the results depends, to a certain extent, on the impact model used. The required seismic gap to prevent pounding proposed in seismic codes provide unconservative results in certain cases. Some drawbacks face the proposed mitigation measures for structural pounding.
