Abstract
One common type of existing structure is the steel frame with semi-rigid connections. In previous studies, analytical models have been developed, the effects of floor slabs and masonry infills have been studied, and parametric response analyses have been performed. The report summarizes work on the low-cycle fatigue behavior of a common type of semi-rigid connection, those made of top and seat angles. Nineteen tests were performed using various load histories and they showed that the hysteretic energy-life and rotation-life models are applicable for this type of connection. The analysis showed that if the plastic hinge rotations are kept below 2%, the connection can sustain at least fifty cycles of complete load reversals. The report contains a valuable database on the cyclic behavior of one type of semi-rigid connection.
