Question
A floor slab 100 mm thick is cast monolithically with beams 250 mm wide 450 mm deep
spaced 1.2 m on centers, on simple supports over a span of 5.0 m. The floor supports a
superimposed service dead load of 1.0 kPa and service live load of 2.1 kPa. Usingf.-21
MPa, long bar f, = 415 MPa, calculate the following:
1.
Factored uniform load on a typical interior beam in kN/m using load factors of 12
for dead load and 1.6 for live load.
B. 11.448
Effective flange width of a typical interior beam in mm.
B. 1,850
A 8.928
C 11.028
D. 9.960
2.
A 1,500
Required amount of 16-mm-flexure bars for a typical interior beam in positive
bending Use 10-mm-dia. stirrups
C. 1,200
D. 1,466
3.
B. 246 mm
C.331 mm
D. 427 mm
