STAIRS DESIGN [ACI 1995 STRENGTH DESIGN METHOD]
Stair Name :
    Stair Name :
    Number of stair level :
  • Material Strength:
      • Concrete strength : f'c
    		= kg/cm2.
      Yeild stress of steel (,ain steel) : fy
    		= kg/cm2.
      Yeild stress of steel (tempurature steel) : fy
    		= kg/cm2.
      b1
    		= (beta)
  • Section Dimension:
      • Span Length (L)
    		= m.
      Story heigth
    		= m.
      Span Width
    		= cm.
      Width of stair level
    		= cm.
      Height of stair level
    		= cm.
      Covering distance
    		= cm.
      Diameter of steel
    		= mm.
      Stair thickness
    		= cm.
      Require stair thickness
    		= cm.
      Effective depth (d)
    		= cm.
  • Acting Load:
      • Live Load
    		= kg/m2.
      Compute weight (DL)
    		= kg/m2.
      Factored MU
    		= kg-m.
  • Computation Results:
      • Maximum As
    		= cm2.
      Minimum As
    		= cm2.
      Required As
    		= cm2.
      Required Av
    		= cm2.
  • Select steel:
      • Select types of deformed bars (SD) :
      Main steel :
    		 @cm As = cm2
      Tempurature steel :
    		 @cm. Av = cm2/m require @cm.
