WebWidth of the rectangular beam = 352 mm. The effective depth of the beam = 462 mm. Factored uniformly distributed load = 63 kN/m (including its own weight) Concentrated factored load = 44 kN at midspan. Span of the beam = 5.88 m. Reinforcement ratio = 0.72 times the minimum reinforcement ratio. Concrete compressive strength = 34 MPa. WebThe most usual is an I shape section, placed at 0.6 m to about 4.0 m apart with cast in situ concrete slab. The formwork of the slab is often created by a series of thin precast concrete slab elements. The span/depth ratio of 18 is usual for decks with beams 2–3 m apart. A span/depth ratio of 25 is possible for continuous bridge decks.
