摘要: 施工模拟方法能在结构分析中合理反映建筑结构逐层施工、逐层施加荷载的性质。经过对结构建造过程的分析研究,利用施工过程中的物理特征,在有限元变列高解法的基础上,通过改进传统的活动列解法和预处理共轭梯度(PCG)法,提出并实现了两种施工模拟快速计算方案。研究表明,与现有的许多计算方案相比,它们大大提高了计算效率,能够较好地满足实际工程分析的要求。

Abstract: Construction simulation is an approach that reflects level-by-level construction of high-rise buildings.Based on building construction process,two fast strategies for construction simulation are proposed by amending the existing skyline and preconditioned-conjugate-gradient(PCG)solvers.It is shown that the two strategies proposed can greatly increase the speed of analysis,and they are applicable to practical problems.
