But if this is a minor loading, not part of a major load carrying column, then a check for punching shear might be referenced through the "Plain Concrete" section 22 of 318. Short …
WebApr 11, 2024 · Reinforced concrete one-way slabs under concentrated loads can develop different shear failure mechanisms: as wide beams in one-way shear, punching shear around the load or a mixed mode between them. Web1 Answer. As has been mentioned in the comments, there is no specific combination of dimensions that mean that punching shear is not a problem. An Engineer may make a judgement that a check isn't required based on experience, but a check would always be the safe option. ACI (American Concrete Institute) even has a similar question in its ...
