About this detail

Kicker bracing is added to an existing concrete-encased steel beam supporting a concrete slab. The kicker brace consists of double angles, 2L3x3x1/2, connected to 3/4-inch thick gusset plates located between existing beam ties using seven-eighths-inch diameter A325-X bolts at each end. The existing concrete encasement is chipped back and patched with concrete after brace installation, with existing reinforcing bars remaining undamaged. The concrete surface is coated with an epoxy bonding agent, and 3/4-inch by 4-inch square plates are provided at midspan and quarter points along the brace.
