Design of Staircases:
There were two staircases in the building to design. Design of main staircase is detailed here.
Choice of layout:
Floor to floor height = 4600mmNo. of rises = 24Height of rise ® = 4600
24= 192mm <175mm and acceptable
for public buildings. Rise=200mmGoing (G) = 300mm Going=250mm
2R+G = 2*200 +300= 700mm
(Appro. 600mm )Hence Not OK.
Nosing is not going to provide hence, tread and going are equal.
Stair span and Waist Thickness for Typical flights:
Staircase was supported between two landings and landings were designed to span perpendicular to the span of flights.
BS8110Cl.3.10.1.3 Effective span =
= 6.9+0.5(1.7+0)= 7.75m
Cl.3.10.2.2 Length of stairs (%) = (6.9/7.75)*100% = 89.00% >60%
Hence span/depth enhancement is possible.
I.S.E. manual Assume span/depth ratio of 31 for continous oneway spanning staircase. Table3
Span/depth = 31*1.15= 35.65
Effective depth = 7750/35.65= 217mm
Assume cover 25mm (mild exposure conditions and 2hr fire resistance)and using 12mm bars, choose h=275mm and Waist thickness
d=275-25-8 = 242mm =Hence waist thickness was selected as 275mm.

Design for bending
Specimen calculation for second flight:
The staircase can be idealised as follows:
W1 = 18.9kN/mW2 = 16.7kN/m
((21.31*0.85*(4.6+0.425))+(23.5*4.6*3.2))/(4.6+0.85)= 80
4.05= 80.17kN
21.31*0.85+23.5*(4.6+0.85)-80.17= 66
= 66.02kN
0.65 <x< 3.15
Mx = -
d(Mx) = - 8.125x- 14.1x+9.165d(x)
0 = 27.4-22.22x+9.165x = 2.1m
Mmax = (27.4*2.1)-(12.5*.65*1.775)-(14.1*1.05)= 28.3kNm
