Two way nd one way distribution when length /width is less than 2 it has two way behavior nd above 2 it has one way behavior in two way behavior slab has bending in both axis and distribution of loads r shared by all support whearas in one way slab bending is in one direction only nd only two support takes load. In this video we learn that how to calculate overlapping length in beam, column and slab visit our website for civil engineering blogs: wwwcivilsolutionoff. Usually, the two-way slab is adopted when the length and width of the slab is more than 4m well to make you perfect in bar bending schedule for a slab, i am considering a one-way slab and two way slab as shown in the figure.
One way slab vs two way slab | difference between one way slab and two way slab two way slab as width/length 2 reply abdi cadiim says april 16, 2015 at 12:20 am mashaallah this page is usefull for all engineers i hope to get alot of theory reply asish panigrahi says. When a reinforced concrete slab is supported by beams on all the four sides and the loads are carried by the supports along both directions, it is known as two way slab in two way slab, the ratio of longer span (l) to shorter span (b) is less than 2.
In this video we learn that how to calculate overlapping length in beam, column and slab visit our website for civil engineering blogs: wwwcivilsolutionofficialcom. One-way and two-way slabs one-way slabs transfer the imposed loads in one direction only they may be supported on two opposite sides only [fig 11(a)], in which the structural action is essentially one-way, the loads being carried in direction perpendicular to length of a rectangular slab are accounted for approximately by designing the. The slabs having ratio of longer length to its shorter length (l y /l x) greater than 2 is called one way slab otherwise as two way slab in one way slab main reinforcement is parallel to shorter direction and the reinforcement parallel to longer direction is called distribution steel. One way slab and two way slab difference cutting length of bent up bars if you missed that please read that posts quick recap, one way slab: ly/lx 2: two way slab: ly/lx : 2 slab reinforcement calculation one way slab reinforcement detailing the biggest misconception is considering beam outer to outer as slab span please refer the below. This video describes how the the reinforcement is placed at the site two way slab is a slab in which the ratio of longer side to the shorter side is less th.
Length of longer(ly) span / length of shoter span(lx) is more than 2 then that slab is considered as a one way slab becoz this slab will bend in one direction ie in the direction along its shorter span. Notes on one way slab design -dr e r latifee question: define the term slab, one way slab, two way slab, shrinkage and temperature reinforcement, main reinforcement such slabs are designed as one-way slabs where the span length (l n) is equal to the length of short direction.
8 chapter 8: design of one-way slabs 81 introduction a slab is structural element whose thickness is small compared to its own length and width slabs are usually used in floor and roof construction according to the way loads are where l is the span length in the direction of bending 8212 minimum concrete cover. In typical cases, beams, one-way slabs, and two-way slabs will be tension controlled sections, so that the strength reduction factor is equal to 09 in accordance with section 93.
8 chapter 8: design of one-way slabs 81 introduction a slab is structural element whose thickness is small compared to its own length and width slabs are usually used in floor and roof construction according to the way loads are transferred to supporting beams and columns, slabs are classified into two types one-way. Even when a rectangular slab is supported on all the four edges, the slab may be considered as a one-way slab if the length-to-breadth (l/b) ratio of the slab is equal to or greater than two a one-way slab is designed for the spanning direction alone the main tension reinforcing bars of such slabs run parallel to the span.
