摘要：为了研究附加交叉斜筋与环形钢筋对钢筋混凝土板（RC板）抗爆性能的影响，采用LS－DYNA软件对爆炸荷载作用下RC板进行了数值分析。选取典型的RC板抗爆试验文献作为参考依据验证了数值分析方法的正确性，并研究了爆炸荷载作用下，附加交叉斜筋与环形钢筋的RC单向板与RC双向板的动力响应与破坏形态。结果表明，选择合理的材料模型，数值分析结果可以精确地与试验结果相吻合。附加交叉斜筋与环形钢筋的单向RC板与双向RC板可以有效减小板中心最大位移与最大加速度，更加充分发挥受力钢筋的作用，降低板的破坏程度。附加交叉斜筋与环形钢筋均可提高RC板的抗爆性能，且提高程度大致相等。 Abstract: In order to study the influence of anti－explosion performance for RC slab with additional cross reinforced and circular reinforced, numerical analysis was carried out for RC slab under blast load using LS－DYNA. The typical experimental literature of RC slab was selected as the reference basis to verify the correctness of numerical analysis method. The dynamic response and failure pattern of RC one－way slab and RC two－way slab with additional cross reinforced and circular reinforced under blast load was studied. The results show that numerical analysis can be exactly in accordance with the experimental results for using reasonable material models. Both one－way slab and two－way slab with additional cross reinforced and circular reinforced can reduce the central max－displacement and max－acceleration effectively, give full play to the role of reinforcement, and decrease the damage of those RC slabs. Both additional cross reinforced and circular reinforced can improve the anti－explosion performance of RC slab and the improvement is roughly equal.
