Regional seismic damage prediction based on multiple-degree-of-freedom shear model and nonlinear time-history analysis can comprehensively consider the characteristics of buildings and ground motions. Two major challenges of applying such methodology, namely (1) parameter determination and (2) damage assessment of buildings in urban scale, are addressed in this study. The reliability of the proposed methods are validated using the tests of three individual buildings and the observed seismic damages of Longtoushan Town in 2014 Ludian earthquake of China. Finally, a regional seismic damage prediction is performed for a large urban region, which demonstrates the applicability and scalability of the proposed methods.
