Static Behavior of Beam-to-Column Moment Connections

A review is presented of tests on beam-to-column moment flange connections. The main objective of these tests was to study the behavior and to develop the design method for flange moment connections. A test program of flange connections consisted of 12 full-size beam-to-column connections. This test series included specimens representing connections for the lower stories, middle stories, and upper stories of a multi-story frame. Primary attention is focused on strength, deformation capacity and overall stiffness of the connection. The load-deflection plot of each connection is compared with its control test behavior, in the adequacy of AISC specifications is studied.
