Question
A simply supported beam of span 6 m is resting on a 230 mm wide brick wall. Assume depth of beam is 85 mm per 1 m span and also assume width of the beam equals width of the support. The factored dead load of the beam is
A.
26.39 kN
B.
21.11 kN
C.
17.6 kN
D.
30.2 kN
Answer ( Option A)

26.39 kN

Solution

Depth of beam ⇒85 × 6510 mm0.51 m
So, volume of beam ⇒ 0.51 × 6 × 0.230.7038 m3
Weight of beam ⇒ Volume × Unit weight
⇒ 0.7038 × 2517.595 kN
Factored weight of beam ⇒ 1.5 × 17.59526.39 kN
