Question
Download Solution PDFA reinforced concrete beam is subjected to the following bending moments.
Moment due to dead load = 50 kNm
Moment due to live load = 50 kNm
Moment due to seismic load = 20 kNm
The design bending moment for limit state of collapse is:
Answer (Detailed Solution Below)

Moment due to Dead load (DL)= 50 kNm
Moment due to live load (LL) = 50 kNm
Moment due to Seismic load (EL) = 20 kNm
Computation:
Design bending moment is Maximum of the following
1) Mu considering moment due to dead load and live load
Mu = 1.5 (DL+LL) = 1.5 x (50+50) = 150 kN-m
2) Mu considering moment due to dead load and Seismic load
Mu = 1.5 (DL+EL) = 1.5 x (50+20) = 105 kN-m
3) Mu considering moment due to dead load, live load and seismic load together
Mu = 1.2 (DL+LL+EL) = 1.2 x (50+50+20) = 144 kN-m.
So the answer is Max of (150, 105, 144 kN-m) = 150 kN-mLast updated on May 28, 2025
