Punching-resistant concrete-filled steel tube column foot structure and punching-resistant capacity estimation method thereof
The invention belongs to the technical field of building structure engineering, and particularly relates to an anti-punching concrete-filled steel tube column foot structure and an anti-punching capability estimation method thereof. The punching-resistant concrete filled steel tubular column is characterized by further comprising a plurality of punching-resistant annular plates welded to the outer side of the concrete filled steel tubular column and stiffening plates connected to the bottoms of the punching-resistant annular plates, and anchor bolt supports are arranged in the middles of the column foot anchor bolts; the upper surface of the punching-resistant annular plate located on the uppermost layer is tightly attached to the lower edge of a surface rib of the concrete foundation, and the surface rib of the concrete foundation is welded to the punching-resistant annular plate on the uppermost layer. The lower ends of the longitudinal steel bars of the concrete filled steel tubular column extend to the anti-punching annular plate located in the middle and are bent and welded to the anti-punching annular plate. And by adding a plurality of anti-punching surfaces, the anti-punching bearing capacity of the foundation is increased, and uniform transmission of stress of the whole column foot is ensured.
本发明属于建筑结构工程技术领域，特别涉及一种抗冲切钢管混凝土柱脚结构及其抗冲切能力估算方法。其特征在于，还包括焊接在钢管混凝土柱外侧的多个抗冲切环板以及连接在抗冲切环板底部的加劲板，在所述柱脚锚栓的中部设置有锚栓支架；位于最上层的抗冲切环板上表面紧贴混凝土基础的面筋下缘，混凝土基础的面筋焊接于最上层抗冲切环板上；所述钢管混凝土柱的纵向钢筋下端延伸至位于中部的抗冲切环板上并弯折焊接于抗冲切环板上。通过增加多个抗冲切面，增加基础的抗冲切承载力，保证柱脚整体的受力均匀传递。
