Such as: load area and shape, strength of concrete, composition of concrete, depth of slab, load position ratio of reinforcement, punching shear reinforcement and scale effect.
The parameters in the aeries include: amount of longitudinal reinforcement, amount of transverse reinforcement, shear span-to-depthratio, thickness of tube wall and strength of concrete.
试验中的主要参数有：纵向钢筋的数量、横向配筋率、剪跨比、管壁的厚度及混凝土强度。

The results show that specimens mainly present bending-shear failure modes, and shear failure is easy to appear in the middle of webs in those specimens with big sectional depth-thickness ratio.
