Elastic and Inelastic Multi-Storey Buildings Under Earthquake Excitation with the Effect of Pounding
S. Mahmoud and R. Jankowski

Abstract:
In this study, an investigation is carried out to analyze the difference in considering adjacent multi-storey buildings to behave elastically or inelastically on the response of structures under earthquake excitation with the effect of pounding. In the study, both structures are modelled as four-storey systems and the nonlinear viscoelastic model is used to simulate pounding force during collisions at different storey levels. Three different ground motion records with different Peak Ground Accelerations (PGA) are applied to conduct the numerical simulations. The study is carried out for two cases: (1) two adjacent buildings are considered to be elastic and (2) two adjacent buildings are considered to be inelastic. A formulation of the equation of motion for two elastic and inelastic buildings is presented. The influence of the gap distance on the structural response (peak displacement, acceleration and pounding force) is also investigated. The results clearly show that modelling the colliding buildings to behave inelastically is really essential in order to obtain accurate structural response under earthquake excitation.
