To determine the required flexural strength at one end of a beam in a concrete frame, the moments produced by dead, live, and wind load are

where the minus sign indicates that the beam end is subject to counter clockwise moment while the plus sign indicates clockwise moment. Both the plus and minus signs are assigned to M_w because the wind load can act on the building in either direction. Compute the required flexural strength for both positive and negative bending.
