【摘要】 介绍了钢筋混凝土框架结构计算机仿真和并行计算的研究现状。数值仿真主要采用有限元、离散元等数学物理模型,而可视化技术及图形仿真基于图形学和图像处理技术,是驾驭计算过程及理解大体积数据的唯一有效途径。有限元并行计算有SBS、EBE两种策略,非线性求解有直接与迭代解法,动力时程分析有显式、隐式和精细时程积分法。最后介绍了并行计算在钢筋混凝土结构分析中的应用。更多还原

【Abstract】 The paper introduces the present state of computer simulation and parallel computation of R C buildings.Numerical simulation mainly is performed by finite element method and discrete element method in physics;based on computer graphic techniques and image processing techniques,visualization and graphic simulation are a shortcut method to steer the calculation process and to comprehend the computation results.In the parallel computation,there are two strategies,namely SBS and EBE;for the nonlinear problem solution,there are direct and iterative algorithms,but for dynamic analysis there are explicit and implicit integration,and high precision direct integration. And the application of parallel computation into the analysis of R/C structures is described at last.更多还原
