摘要
以粘钢加固混凝土梁的仿真分析为例,研究仿真模拟的失败原因。研究结果表明:仿真模拟受材料本构关系、有限元模型、网格尺寸、边界约束条件和荷载步及收敛准则等因素影响,计算前提的微小改动都能导致仿真分析的不收敛。对此,文章在结论中对后续仿真软件的编制提出若干建议。
Causes of simulation failures were discussed based on the analysis of reinforced concrete （RC） beams strengthened with external bonding of steel plates. It is indicated that minor changes of the material constitutive relation, the finite element model, meshing size and boundary constraint conditions, loading step improving the simulation and convergence criteria may affect the simulation results. Suggestions on softwares were presented.
