Simply supported stair
Design a straight flight stair in a residential building supported on reinforced concrete wall 1.5 m )(center to center)
L.L = 3kN/m2
Covering Material = 0.5kN/m
The riser are 16cm and goings are 30 cm
Loads and Analysis
D.L(
O.W
) =0.34*0.075*25 + 0.5*0.16*0.3*25=1.24 kN/m
D.L (covering material) = 0.5 kN/m
D.L (total) = 1.74 kN/m
L.L =3*(0.3) =0.9 kN/m
