Additional information

Performance Based Engineering (PBE) is a lifetime assessment of buildings which are assumed to experience multiple earthquakes. Paper explores in detail specific effects of combined main- and after-shocks and arising cumulative damage, using novel multiple-criteria classification of large dataset of recorded aftershocks. These are run through numerical models of generalised buildings to reveal characteristics that lead to increased ductility demand. Paper points to need to broaden PBE and underpins selection of input earthquakes for £3M+ Advanced Gas-cooled Reactor (AGR) physical-scale model tests being conducted for EDF-Energy (Contract No. 4840383278).
