How this node works
At the column the load concentrates and tries to push it up through the slab along a cone of shear. Vertical shear reinforcement — studs or links around the column — stitches the cone together; a drop panel or column head, and a generous depth and cover, complete the defence. It is the check that sets the slab thickness.
