Construction simulation method focuses on the simulation of time-variant properties of materials and structural systems. A three-floor frame structure is established to study construction simulation using B3 model. Internal forces of the methods with or without consideration of the construction process are compared. Internal forces of the methods with or without consideration of inelastic deformation are compared. Results show that calculating inelastic deformationwith B3 model is feasible. Programming method with considering of inelastic deformation and construction process is well applied in construction simulation.Keywords: construction simulation；time-variant properties；inelastic deformation；B3 model
