摘　　要：施工模拟方法广泛应用于施工阶段差异变形计算、标高补偿和水平度校正等方面。施工模拟主要是对施工阶段结构的材料时变性和体系时变性进行模拟。建立了三层框架结构,用B3模型辅助编程,进行施工模拟计算;比较了考虑施工过程和不考虑施工过程的结构内力,比较了考虑非弹性变形和不考虑非弹性变形的结构内力。结果表明,用B3模型计算非弹性变形是可取的,既考虑非弹性变形又考虑施工过程的编程方法能很好地进行施工模拟。Construction simulation method is widely used in the calculation of the differential deformation,elevation compensation and floor level correction in construction stage. 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.
