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.

The study of welded semi‐rigid connections in fire

The Structural Design of Tall and Special Buildings, 2011
SUMMARYConsidering the deterioration of steel properties by temperature increase and the importance of the influence of connection behavior on the behavior of steel structures, we find that the exact understanding of the behavior of a specific steel connection in fire as well as the information about the effect of fire on the principal constitutive ...

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.

Semi-Rigid Composite Connections for Gravity Loads

Engineering Journal, 1990
Double web angles, top and seat angles, and seat angle and web clips are some of the most common connections used for floor beams in braced steel frames. These connections are considered to be rotationally weak, and therefore design proceeds along the assumption that these connections can be idealized as pins. In reality, because these connections have

Formulas for Beams with Semi-rigid Connections

Engineering Journal, 1996
This paper presents practical formulas for beams with semi-rigid connections of variable stiffness, and describes certain limitations for application of these formulas. Using the tables of formulas, the engineer is able to rapidly determine the effect of a partially restrained connection. A practical example illustrates the application of the formulas.

Analysis of Building Frames with Semi-Rigid Connections

Transactions of the American Society of Civil Engineers, 1942
Methods applicable to the analysis of building frames with semi-rigid riveted or welded connections between the beams and columns are presented in this paper.

Semi-Rigid Connections in Steel Frames

2000
The purpose of this chapter is to present the interaction of the steel frames and their joints and to describe an acceptable method of joint design. A key problem in dealing with joints is their classification, the basis of which is described in the Eurocodes and other available design codes in a variety of different ways.
