Given: 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)=1.5x(50+50)=150‌kN−m 2) Mu considering moment due to dead load and Seismic load Mu=1.5(DL+EL)=1.5x(40+20)=105‌kN−m 3) Mu considering moment due to dead load, live load and seismic load together Mu=1.2(DL+LL+EL)=1.2x(50+50+20)=144‌kN−m. So the answer is 150 kN-m
