تصميم Two Way Slab

If a slab is supported on all the four sides but the ratio of longer span l to shorten span b is greater than 2 then the slab will be considered as one way slab.

تصميم two way slab. So the slab is one way where l b 2. Transferred to supporting beams and columns slabs are classified into two types. Determination of two way slab. Variation in successive spans 33.

Determine moments at critical sections in each direction normally the negative moments at supports and positive moment near mid span. Slab thickness of 13 in. For slabs on beams for one panel. One way slab one way slabs are those slabs with an aspect ratio in plan of 2 1 or greater in which bending is primarily about the long axis.

Column offset 10 in each direction. Under the action of loads it is deflected in the. Three or more spans in each direction. Two way slab design examples part 2 تصميم البلاطة التي تعمل في اتجاهين الجزء الثاني duration.

Distribute moments transverse at critical sections to column and middle strip and if. Two way slabs 3 4. The basic design procedure of a two way slab system has five steps. Is not adequate for two.

Is adequate for one way shear. When the ratio of the longer to the shorter side l s of the slab is at least equal to 2 0 it is called one way slab shown in figure 8 1 a. Total load is carried in the direction perpendicular to the supporting beam. One way slab is supported on two opposite side only thus structural action is only at one direction.
