This document discusses critical sections for moment and shear design of structural members. For moment, the critical section is at the face of the support. For shear, if the reaction introduces compression into the end region, sections within a distance d of the support can be designed for the same shear as at distance d. Typical support conditions are shown for locating factored shear and moment.

26. CRITICAL SECTION FOR MOMENT:
 For monolithic construction, the
moments computed AT THE FACE OF
THE SUPPORT shall be used in the
design of the members at those
section
CRITICAL SECTION FOR SHEAR:
 When the reaction in the direction of the
applied shear introduces compression into
the end region of the member, sections
located at a distance < d from the face of
the support may be designed for the same
shear as that computed at distance d
