ABAQUS显式分析方法在钢筋混凝土结构中的应用

Application of ABAQUS/Explicit in Reinforced Concrete Structures

为了考察ABAQUS显式分析方法在钢筋混凝土结构上应用的适用性和准确性,用显式与隐式两种分析方法对迭代算法和求解时间进行了对比,并且对钢筋混凝土悬臂梁分别进行了隐式和显式模拟分析。用结果曲线详细地对比可知,显式分析方法能够在解决材料失效和破坏导致的收敛问题的基础上,较为准确地模拟钢筋混凝土结构响应。最后,给出了采用显式分析参数定义时的注意事项及判定分析结果稳定性的方法。

In order to verify the applicability and validity of ABAQUS/Explicit in reinforced concrete （RC） structures simulation, a comparison between ABAQUS/Explicit and ABAQUS/Standard is carried out. The comparison scope includes the iteration algorithm and computation time. Moreover, a RC cantilever is set as an example to explain the differences between these two analysis methods. It is verified by investigating on the load-deflection curve that RC structures can be simulated by ABAQUS/Explicit if the parameters are set reasonably. The different energy histories simulated bv ABAOUS/Exnlicit are advised to estimate the stability of simulation.
