A beаm is pаrt оf the frаming system fоr the flоor of an office building. The floor is subjected to both dead loads and live loads. The maximum moment caused by the service dead load is 55 ft-kips, and the maximum moment for the service live load is 54 ft-kips (these moments occur at the same location on the beam and can therefore be combined). If ASD is used, determine the required moment strength, Ra.
