The seismic damage of buildings predicted by the conventional intensity-based damage probability matrix method differs significantly from the actual damage. To better simulate the seismic damage of urban areas by taking full consideration of the seismic resistances of buildings and the features of ground motions, an improved seismic damage simulation method based on multiple-degree-of-freedom concentrated mass shear (MCS) model and nonlinear time-history analysis (THA) is proposed. The method has the following advantages: (1) easyto-construct building model; (2) reliable nonlinear parameter determination method; and (3) high computation efficiency. Only the building attribute data (i.e., year of construction, number of stories, height, design intensity and structural type) are needed as input for the automatic model generation and parameter determination. Based on extensive experimental and analytical results, the parameter determination method for three types of most widely used multi-story buildings (i.e., reinforced concrete frame structures, reinforced masonry structures and unreinforced masonry structures) is proposed, the reliability of which is verified by comparing with the experimental results of individual structures. Powered by the GPUbased high-performance computing, the simulation can be performed with very high efficiency, which is sufficient for regional damage simulation of large urban areas. With the proposed method, the seismic damage of buildings at the epicenter area of 2014 Ludian Earthquake is simulated. The method can better consider the capacity of each building on each floor and the time/spectral domain characteristics of the ground motions. In consequence, the prediction results agree well with the actual damage. This research may provide a reference for the vulnerability analysis of multi-story buildings in pre-earthquake scenario and the fast seismic damage assessment in post-earthquake scenario.
