@iconstructionandpartners: ๐ How to Calculate Number of Steps, Risers & Treads A well-designed staircase ensures safety, comfort, and efficient use of space. To calculate the number of steps, start by dividing the total floor-to-floor height by the selected riser height. The number of treads is usually one less than the number of risers. Proper riser and tread dimensions provide a comfortable walking experience and comply with standard building practices. Key Points: ๐ Total Stair Height = 3000 mm ๐ Standard Riser Height = 150 mm ๐ฃ Standard Tread Width = 300 mm ๐งฎ Number of Risers = Total Height รท Riser Height = 20 ๐ช Number of Treads = Risers โ 1 = 19 ๐ซ Mid Landing Width = 1200 mm ๐งฑ Landing Thickness = 100 mm ๐ Recommended Stair Angle = 25ยฐโ45ยฐ ๐งฑ Calculate concrete separately for steps, landings, and waist slab. โ Total Concrete Volume (as shown) = 1.0715 mยณ ๐ก Thumb Rule: 2 ร Riser + Tread = 600โ650 mm for a comfortable staircase. #CivilEngineering #StairDesign #Staircase #Construction #StructuralEngineering
