摘要:
为了研究板厚、肋宽、配筋率对空心板冲切性能的影响,对9个空心板柱节点试件进行了抗冲切试验,得到不同条件下空心板柱结构节点的开裂荷载、极限荷载、板底位移以及钢筋和混凝土的应变数据.采用数据对比和理论分析的方法,研究不同板厚、孔径、肋宽和配筋率对冲切承载力的影响.试验结果表明:空心板柱结构节点的冲切破坏形式为脆性破坏;初始裂缝发生在顺管向加载柱板底外边缘和板底边之间;顺管向和垂直管向的冲切角度分别为50°~60°和30°~45°,即顺管向的冲切角大于垂直管向的冲切角;增大肋宽、板厚和板底配筋率可以提高节点的抗冲切承载力.
Abstract:
To study the effects of thickness, rib width and steel ratio on punching shear capacity, nine hollow slab-column connection members were tested under punching shear force and the experimental data such as cracking load, ultimate load, vertical displacement, and steel and concrete strain were obtained. By data analysis and theoretical analysis, the effects of thickness, diameter, rib width and steel ratio on punching shear capacity were analyzed. The experimental results show that the failure mode of the hollow slab-column connection is fragile failure. The crack firstly takes place between the slab edge perpendicular to tube direction and the column side at the bottom of slab. The cutting angle along the tube direction ranges from 50° to 60° which is larger than that perpendicular to tube direction ranging from 30° to 45°. The increase of the thickness, rib width and steel ratio can improve the punching shear capacity.
