    Compared

    with

    STM

    models,

    the

    longitudinal

    reinforcement

    is

    similar.

    However,

    the

    required

    amount

    of

    vertical

    reinforcement

    is

    much

    larger.

    The

    traditional

    beam

    theory

    is

    much

    more

    conservative

    in

    the

    shear

    design

    of

    STM

    models.
