Span to depth ratio for continuous beam
Web1. máj 2024 · When the beam depth increased from 180 mm to 240 mm, the nominal shear stress was significantly reduced, but no obvious size effect was found beyond 240 mm. Fahmi et al. [16] tested seven UHPC deep beams with variables of shear span to effective depth ratio (λ) and percentage of silica fume (p) in the UHPC. Their result indicated that … Web24. nov 2024 · A steel beam with span L under constant moment M will deflect Δ = ML 2 /8EI at midspan. The maximum fiber stress f at d/2 will be f = M.d/2I. so M/I = 2f/d where d is the depth of the beam. Thus Δ = f.L 2 /4dE. Setting Δ as L/360 and re-arranging, gives L/d = E/90f. Setting Δ as L/240 gives L/d = E/60f.
