Partially Restrained

This paper explores rotational capacities and demands in thick top-and-seat (cleated) angle partially restrained connections subjected to monotonic and cyclic loads. The results of test on full-scale angle connections are described first, and are then compared to published curve-fitting models for these types of connections. The data indicates that the curve-fitting constants of some existing mathematical models cannot be extrapolated to thick angles. The results indicate that these connections are capable of providing very ductile behavior and constitute an ideal back-up structural system in steel frames.
