Abstract: Based on ABAQUS software, the elasto-plastic time-history analysis for a new complex high-rise building in Shenyang was conducted. The realization methods of elasto-plastic time-history analysis were introduced, which include the estabishment of the whole model, component simulation, material constitutive and integration method. The seismic performance was evaluated in terms of general structural stability and structural components damage, which could provide a reference for other similar projects.

Keywords: performance-based seismic design; elasto-plastic time-history analysis; ABAQUS
