Web16. aug 2024 · If the ratio of longer span to shorter is equal to or less than 2 so, it is called a two -way slab. As per IS 456: 2000 clause no 23.2.1. ... Total depth of slab is 165 mm. If Shorter span > 3.5 m and L.L. > 3 KN/m 2; Then, for basic value you go to table no. 1. effective depth formula . Web6. jún 2014 · Behaviour of beam depends on its depth. A beam is considered as deep, if the depth span ratio is 0.5 or more. In the available beam theories, we have to apply correction in case of deep beams. In the present work, method of initial functions (MIF) is used to study the effect of depth on the behaviour of concrete beam. The MIF is an analytical method of … flat rate mailing boxes usps
