Abstract—A representative case study of potential
earthquake-induced pounding between adjacent R/C frame
buildings with insufficient separation gaps is examined in this
paper. The height of the two examined buildings is the same,
but their response is affected by considerable torsional
pounding effects. An upgraded version of the traditional linear
viscoelastic model for the numerical time-history analysis of the
dynamic impact problem is proposed and implemented in the
finite element model of the buildings. The results of the
assessment enquiries carried out in current conditions, and a
damped interconnection-based mitigation solution based on the
incorporation of pressurized fluid-viscous dissipaters across the
inadequate separation gaps, are presented. Evaluations of the
benefits provided by the retrofit intervention, and some of its
technical installation details, are finally offered.
