Three structural steel beam connection details show framing conditions for beams with varying depth offsets at supporting columns or girders. The first detail accommodates a maximum six-inch depth difference using a full-depth connection plate and web stiffeners on the supporting member. The second detail handles six to twelve-inch depth differences with a gusset plate welded beneath the supported beam flange. The third detail addresses depth differences greater than twelve inches using an L4x4x1/4 angle brace fastened with one-inch diameter A325SC bolts at each end and a three-eighths-inch center plate.
