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。
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 antidetonation 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 explosionproof wall ; increasing the longitudinal reinforcement ratio and adding the thickness of wall can improve the anti-detonation capability of explosion-proof wall as well.
