تصميم Two Way Solid Slab

8 2 1 one way solid slabs 8 2 1 1 minimum thickness to control deflection aci code 9 5 2 1 specifies minimum thickness values for one way solid slabs shown in table 8 1.

تصميم two way solid slab. One way slab is supported on two opposite side only thus structural action is only at one direction. For the love of physics walter lewin may 16 2011 duration. 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. Variation in successive spans 33.

For slabs on beams for one panel. Two way slab design examples part 2 تصميم البلاطة التي تعمل في اتجاهين الجزء الثاني. Solid slab وهى البلاطات المرتكزة على كمرات وتخانتها لا تتعدى 15 سم. Ll 2 dl 4.

Three or more spans in each direction. What is one way slab. So the slab is one way where l b 2. 2 بلاطة ذات اتجاهين two way slab.

The basic design procedure of a two way slab system has five steps. Two way slabs 3 4. When a slab is supported on all four sides and the ratio of long span to short span is equal or greater than two it will be considered as one way slab. They will make you physics.

Two way slabs 8 2 one way slabs in this section two types will be discussed one way solid slabs and one way ribbed slabs. 1 1 b shows two center strips of a rectangular plate with spans l a and l b. Direct design method d d m before discussion of this method we have to study some concepts. Determine moments at critical sections in each direction normally the negative moments at supports and positive moment near mid span.

I e w a and w b. Two way solid slab duration. Lectures by walter lewin. Load transfer in a one way slab b two way slab nilson fig.

Column offset 10 in each direction. 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. Application of l b ratio in first figure slab is supported on two opposite sides only. For uniformly distributed loads of w per square foot of the slab each strip acts approximately like a simple beam uniformly loaded by its share of w.

However main reinforcement bar and distribution bar in transverse direction. Types of one way slab one way slab may be solid hollow ribbed 6. Total load is carried in the direction perpendicular to the supporting beam.
