For spans above 10 m, the values in (a) may be multiplied by 10/span in meters, except for cantilever in which case deflection calculations should be made. Web1. feb 2024 · Span-to-depth ratio limits are proposed to fulfil required ductility. • Ductility limits are more restrictive than deflection limits if δ ≤ 0.9.. Current beams should have limited l/d if high amount of reinforcement is used.. Current slabs (δ = 0.75) present enough ductility if l/d ≤ 20.MC2010/EC2 conditions to use plastic analysis need to be revised.
Web22. sep 2024 · According to IS 456:2000, if effective span to depth ratio is less than 2 in case of simply supported beam, then this type of beam is known as deep beam. Effective span is the depth between centers of support. As soon as depth increases shear strength capacity of beam starts to be decreasing. Web16. aug 2024 · Total depth of slab is 165 mm.
