TYPICAL CALCULATION BS 8110
for Span 1 at 3.60 m from C/L of LH support Reference
Class 3 Tee section, h = 525 mm, bw = 1800 mm hf = 200 mm, bf =3000 mm.
Ac = 1185000mm2, Z top = 120.0E6 mm³, and Z bottom = 93.3E6 mm³
Tendons are unbonded, Ap = 100mm2, fpu = 1,860 N/mm2 and 75.9 mm from soffite
There are 24 tendons, jacked to 1,302 N/mm² or 70.0% fpu
Prestress losses at this section are -2,500.7 kN at transfer and -2,237.1 kN longterm
4.3.5
M = 394.4 kNm hogging, and prestressing force = 2,761.1 kN
Max compression (bottom) = M/Z + P/A = 394.4E3 / 93.3 + 2,761.1 / 1185 = 6.56 N/mm²
< 10.02 N/mm² allowed
Max tension (bottom) = M/Z - P/A = -158.3E3 / 93.3 - 2,761.1 / 1185 = 0.96 N/mm²
< 3.00 N/mm² allowed
4.3.4
M = 400.5 kNm sagging, and prestressing force = 2,497.5 kNMax compression (top) = 400.46E6 / 120.0E6 + 2,497.5E3 / 1185E3 = 5.44 N/mm²
< 13.33 N/mm² allowed
Max tension (bottom) = 400.46 / 93.3 - 2,497.5 / 1185 = 2.18 N/mm²
< 4.73 N/mm² allowed
4.3.7
M = 1,382.7 kNm sagging, and prestressing force = 2,497.5 kN
fpe = 1000 x 2,497.5 / 24 / 100 = 1,040.6 N/mm²Reinforcement d = 480 mm
Rp = 1860 x 100 x 24 / 40 / 3000 / (525 - 75.86) = 0.083
fpe/fpu = 1,040.6 / 1860 x 1.05 = 0.587
Lte = 12,250 mm
fpb (unbonded)
= 1,040.6 + 7000 x (525 - 75.86) / 12,250 (1 - 1.7 x 0.083) = 1,261.1 N/mm² Eq 52
Tendon force = 1,261.1 x 24 x 100 / 1000 = 3,026.7 kN
Rebar force = 460 / 1.05 x 6,283 / 1000 = 2,752.6 kN
Total tensile force = 3,026.7 + 2,752.6 = 5,779.4 kN
Compression block depth, dn = 1000 / 5,779.4 / 0.45 / 40 / 3000 = 107.03 mm
MOR = (3,026.7 ( 525 - 75.9 - 107.03 / 2) + 2,752.6 x (480 - 107.03 / 2)) / 1000 Eq 51
= 2,371.4 kNm > 1,382.7 ok
