Web1. sep 2010 · depth is established, an initial estimate must be made of the reinforcement ratio. If the span length exceeds 23.0 ft (7 m), the depth is multiplied by 23.0/ span length (7/span length) to account for an increased self-weight of the member as span length increases. For flat plates, the depth is multiplied by 27.9/span length (8.5/span length).
