Slab may be supported on walls or beams or columns. Assume corners are held down. Slab supported on two sides and bending takes place predominantly.
Use M20 Concrete and 415 steel. Draw panel of slab and indicate maximum design moments shears and in- plane loads if any per unit width of slab. In two way slab the corners may be held down by restraints or may be allowed to lift up.
Choose Design method Equivalent Frame Method- use elastic frame analysis to. Two Way Slab Reinforcement Details. And minimum percent as one way slab 1000 and according to ACI code is.

Accordingly main reinforcement is. The slab is supported all around walls of width 300 mm. Beamless slabs Beamless slabs are supported only on columns and are applied mostly in large industrial and public buildings.
Slab supported directly by columns are called flat slab. Add to wish list. Two-Way Concrete Floor Slab with Beams Design and Detailing.

Top Extra Bar 8mm 150 mm cc both direction Bar. Is adequate for one-way shear. Development Length L d 40d.
Slab supported directly by columns are called flat slab. Slab shear strength two-way shear Check the adequacy of slab thickness for punching shear two-way shear at an interior column Figure 4. Step 3 Cover to reinforcement Determine cover required to reinforcement as per Tables 116 and 117.
One way spanning slabs. Design the slab system shown in Figure 1 for an intermediate floor where the story height 12 ft column cross- sectional dimensions 18 in. X 27 in interior beam.
Slab supported on two sides and bending takes place predominantly in one direction only is called One Way Slab. 10mm Main Bars 150mm CC spacing. Da h -20 05 d bar db h -20 15 d bar 3- At continuous edges.
10mm Distribution Bars 200mm CC Spacing. 31- Two way beside one way slab use the larger moment as shown below in the figure. In two way slab main reinforcement is provided along both direction.
Use actual effec- tive depth in each direction. In one way slab main reinforcement is parallel to shorter direction and the reinforcement parallel to longer direction is called distribution steel. Choose layout and type of slab.
File was saved as AutoCAD Version 2004 so many can downloaded it. Two Way Suspended Slab Detail. When the ratio LSis less than 20 slab is called two-way slab as shown in the fig.
The slab has to carry a live load of 4 KN per meter square. Slabs could be simply supported. Determine whether the slab is one-way or two-way slab by calculating aspect ratio.
Checkout Added to cart. In one way slab main reinforcement is parallel to shorter direction and the reinforcement parallel to longer direction is called distribution steel. Basic Steps in Two-way Slab Design 1.

Choose slab thickness to control deflection. If ratio of longer span to shorter span is less than 2 then it is two-way slab otherwise one-way slab. X 18 in edge beam dimensions 14 in.
Two-Way Concrete Floor Slab with Beams Design and Detailing CSA A233-14 Design the slab system shown in Figure 1 for an intermediate floor where the story height 37 m column cross- sectional dimensions 450 mm 450 mm edge beam dimensions 350 mm 700 mm interior beam dimensions. The slabs having ratio of longer length to its shorter length LyLx greater than 2 is called one way slab otherwise as two way slab. Lets discussed the design code requirement specified for slab reinforcement details.
Identifies a two-way slab as a slab system designed for flexure in more than one direction. Bending will take place in the two directions in a dish-like form. In general there are similar requirements for one-way and two ways slab when slab reinforcement detail drawings are prepared.
They are classified based on reinforcement placement in the slabOne-way Slab Reinforc. Two-Way Concrete Floor Slab with Beams Design and Detailing. Design steps of two-way slab.
