Experimental Research on Impact Resistance of Half Steel Plate Concrete Structures with Different Tie Bar Details

  • 摘要: 单钢板混凝土组合结构是在钢结构与混凝土结构的基础上发展出来的一种结构形式,与普通钢筋混凝土结构相比,具有承载能力高、密闭性好、抗冲击爆炸性能好等特点,在核电结构安全壳和楼面板等领域具有良好的应用前景。然而,现阶段单钢板混凝土结构体系拉筋的连接型式尚不明确,不同型式拉筋的抗冲击性能也缺乏研究。为研究实际工程中不同构造形式对拉筋破坏机理和抗冲击能力的影响,设计了缩尺比为1∶20和1∶10的单钢板混凝土靶板,采用3种拉筋连接型式,针对不同的拉筋构造开展动力冲击试验,揭示不同拉筋构造在动力冲击荷载作用下的受力机制和破坏模式。结果表明:单钢板混凝土组合结构靶板在局部冲击作用下的破坏模式主要为鼓曲和贯穿,且随着入射弹体动能的增加呈现更明显的局部破坏现象。影响单元板件破坏模式的主要因素是板厚,其次是冲击速度。应用拉筋端锚型搭接式构造,更有利于冲击区域内板件变形以及冲击区域附近动力响应峰值的控制。
