Pounding response of structures under earthquake motions

Pounding of structures is a common phenomenon between adjacent structures with out-of phase response which is caused by lateral seismic motions. Before the introduction of earthquake resistant design many buildings were built without any gaps between them and sometimes connected with one or two structural members. During pounding events, contact forces with high amplitude and short duration are generated which could lead to damage or total collapse of buildings. Over the past two decades, the study of building pounding and precise estimation of these contact forces has been studied by adopting several contact models. However there are still uncertainties with the adequacy of these models as different models produce different results for predicting the response of a single structure. The aim of this research is to develop/expand a contact model which can overcome the disadvantages and uncertaintaies of the existing contact models in predicting the contact forces to model seismic pounding.
