Dowels in footing
WebUnsymmetrical footing – A footing with a shape that does not evenly distribute bearing pressure from column loads and moments. It typically involves a hole or a non-rectangular shape influenced by a boundary or property line. Strap footing – A combined footing consisting of two spread footings with a beam or strap connecting the slabs. WebDowels are commonly used as interface reinforcement between columns or walls and footings. The dowels are set in the footing prior to casting the footing concrete and are subsequently spliced to the longitudinal bars in …
