Frontiers of Engineering Management 2021, Volume 8, Issue 1,   Pages 122-134 doi: 10.1007/s42524-019-0072-x

Abstract: Aftershocks further damage buildings weakened by mainshocks.A framework to predict regional seismic damage of buildings under a mainshock–aftershock (MS–AS) sequenceMoreover, city-scale nonlinear THA is adopted to predict building seismic damage subjected to MS–AS sequencesThe primary conclusions are as follows. (1) Regional seismic damage of buildings under an MS–AS sequencesequence can be generated reasonably by the proposed MS–AS sequence-generation method. (3) Regional seismic
