| 摘 要： | 为了研究钢筋混凝土防爆墙的抗爆能力,采用有限元分析方法对不同纵向配筋率、不同高跨比、不同厚度的墙体在爆炸动态荷载作用下的动力响应进行研究,对各种不同设置的钢筋混凝土防爆墙的抗爆性能进行评估。结果表明:减小高跨比对提高钢筋混凝土防爆墙的抗爆能力最为重要,提高纵向配筋率,增加厚度都能增加防爆墙的抗爆能力。

| Abstract: | In order to study the anti-detonation capability of the reinforced concrete explosion-proof wall,the dynamic response of walls with different longitudinal reinforcement ratio,different ratio of height to span,different thickness under explosion dynamic loading is studied by finite element analysis.The anti-detonation capability of explosion-proof walls with various constitutions is evaluated.The result shows decreasing the ratio of height to span is most important to improve the anti-detonation capability of explosion-proof wall;increasing the longitudinal reinforcement ratio and adding the thickness of wall can improve the anti-detonation capability of explosion-proof wall as well. |
