A design model for semi-rigid connections

Engineering Structures, 1990
Abstract A three-parameter exponential model is proposed to represent the behaviour of top- and seat-angles with or without double web-angle connections. Two of the parameters, the initial stiffness and the mechanism moment, are theoretically defined and extensively compared with those measured from connection test curves.

Optimum design of semi-rigid connections using metamodels

Journal of Constructional Steel Research, 2012
Abstract Considerable efforts were made in the past 15 years to develop strategies for the optimization of steel frames with semi-rigid connections, concentrating on the frames and not the connections, which were designed after the rest of the structure had been optimized.

Behavior of Semi-rigid Composite Connections

Engineering Journal, 1987
The 1978 AISC Specification allows three types of framing. Type 1 is for fully rigid moment connections, Type 2 is for pinned connections (although the moment capacity inherent in these connections is recognized and assumed to act in resistance of wind loads), and Type 3 is for semi-rigid connections.

Unbraced Frames with Semi-Rigid Composite Connections

Engineering Journal, 1990
The benefits of semi-rigid connections are well known and much has been written about their use in braced frames and in Type 2 construction. One of the reasons these methods are not being used frequently by designers is that most semi-rigid connections are highly nonlinear, and analysis of the behavior of frames using them is difficult.
