New formulation for estimating the damping parameter of the Kelvin-Voigt model for seismic pounding simulation

Seismic pounding between adjoining buildings frequently causes serious damage; although collision can be avoided with proper separation, can still occur due to code non-fulfillment, loose requirements of old codes, and seismicity underestimation. Inside this context, this work deals with collision b...

Inside this context, this work deals with collision between two buildings with aligned slabs.

That formulation consists in estimating the damping parameter after a given target value of the coefficient of restitution; the influence, during impact, of the colliding building structures and the seismic excitation is neglected. This paper proposes an alternative approach that releases one of the aforementioned assumptions: the influence of the building structures and their initial separation is taken into consideration. A simplified parametric study oriented to investigate the performance of the proposed strategy is performed; it is found that the accuracy of the Anagnostopoulos formulation is improved in a number of situations.
