摘要:
采用不同力学性能等级的活性粉末混凝土材料,制作3组外包活性粉末混凝土无纵筋型钢组合柱,并在型钢上设置抗剪销钉,对其进行轴压承载力性能试验. 结果表明,型钢与活性粉末混凝土具有良好的协同工作能力,试件破坏时未出现保护层混凝土剥离现象,有较好的整体性能. 提出该组合柱在轴向荷载下有弹性阶段、销钉抗滑移阶段、协同工作阶段、塑性阶段和破坏阶段5个过程,以柱端部劈裂破坏为主要破坏形式,活性粉末混凝土与型钢的强度都能较充分发挥. 参考相关规范提出了该组合结构的近似承载力公式.
Abstract:
We use three levels of mechanical properties of reactive powder concrete (RPC) to produce three groups of encased RPC composite columns with longitudinal reinforcement steel, and set up shear pin and then test the performance of axial bearing capacity. The results show that steel and RPC have strong adhesion. The protective layer of RPC is not peeled off when specimen damage occurs, which means that RPC has a good overall performance. According to the experimental phenomena, we propose five different processes of the composite column under the axial load: the elastic stage, the anti-slip stage, the cooperative working stage, the plastic stage and the failure stage. The main damage form is the splitting failure at column ends. The advantages of RPC and steel can be fully developed. The approximate bearing capacity formula of the composite structure is given.
