LRFD Factored Load of 1.2D + 1.6L

Easyload combinationslrfd
A member carries a dead load of 120 kN and a live load of 80 kN. Using the LRFD combination 1.2D + 1.6L, the factored load is most nearly:
  1. A200 kN
  2. B240 kN
  3. C272 kN
  4. D320 kN
Show solution

Answer: C. 272 kN

Applying the load factors: 1.2(120) + 1.6(80) = 144 + 128 = 272 kN. The unfactored service load is 200 kN, which is what the member would carry in use; the factored value is what the design strength must exceed.
