Analysis of a semi-rigid connection for precast concrete

Proceedings of the Institution of Civil Engineers - Structures and Buildings, 2010
This paper presents a study of a specific type of beam-to-column connection for precast concrete structures. Furthermore, an analytical model to determine the strength and the stiffness of the connection, based on test results of two prototypes, is proposed.

A New Design Idea on Steel Frame - The Active Semi-Rigid Connection Design Method

Applied Mechanics and Materials, 2011
The type of beam-to-column connection in framework structure is determined beforehand in analyzing the frame structure using traditional design method. But it is not comprehensive and exact following that idea.

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.

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.

Effect of semi-rigid connections on steel column strength

Journal of Constructional Steel Research, 1980
Abstract A review has been made of all available experimental data relating to the moment versus in-plane rotational behaviour of practical beam-to-column connection types as used in steel frames. This has clearly shown that all forms of connection possess some stiffness which will act as partial restraint to the column's ends.
