Answer Posted / pratyush mohan jha
to avoid cofusion provide reinforcement in direction
perpendicular to flexural crack.
in case of slab---- yield line is parellel to longer span,
hence reinforcement is provided parellel to shorter span.
in case of beam flexural crack occures parallel to cross
section ( not parallel to length of the beam). hence
reinfocement is provided horizontally parralel to length.
