3. Description of the Project
Villa in UAE consists of 4 stories ( Ground, First, Second and Roof)
F’c = 25Mpa for horizontal element (Slabs and Beams)
F’c = 30 Mpa for Vertical element (Columns, Walls, and Foundations)
Fy = 420Mpa (longitudinal reinforcement)
Fyt = 240Mpa ( transversal reinforcement)
Qa = 1.5kg/cm2 (Bearing capacity of soil)
Height of the Ground Floor 4m
Height of the typical stories 3m
All columns are with minimum dimensions 600x250mm

Eng. Ahmad Traboulsi ETABS & Safe course 8
9. Flat Slab
• Flat slab easy in construction
• Loads:
1. Dead Load = 3 kN/m2 (Type of Slab)
2. Live Load = 2 kN/m2 (residential)
h flat slab = L / 33 =
600+890 𝑥0.5
33
= 22.57cm = 23cm
Eng. Ahmad Traboulsi ETABS & Safe course 9
Where L = L average
h beam = 3 x h slab = 3 x 22 = 66cm so B25x70
10. Stair
• H stair = 18 cm we draw the stair in ETABS as solid slab
• Dead Load on the stair = 3 KN/m2
• Live load on the stair = 4 KN/m2
