钢筋混凝土结构抗内爆性能的有限元优化设计分析

FEM OPTIMIZATION ANALYSIS ON ANTI-EXPLOSION ABILITY OF REINFORCED CONCRETE STRUCTURE

讨论了结构抗内爆动力有限元数值计算中的参数取值、破坏准则问题。使用DYNA软件计算得到的爆炸荷载,采用有限元优化设计技术,分析了空心圆柱体钢筋混凝土结构的抗爆性能,成功地得到了与化爆实验相一致的结果。计算得出的结构响应和破坏规律可供工程设计参考。

The parameter decision and failure criteria in the dynamic FEM modeling on anti-explosion of reinforced concrete structure are discussed. The explosion loads are obtained by DYNA FEM. Using FEM optimization technology,the anti-explosion ability of reinforced concrete hollow cylinders is analyzed. The results are consistent with chemical explosion experiment.
