Structural performance of semi-rigid composite frame under column loss [PDF]

Engineering Structures, 2015
The catenary action associated with significant second order effects plays an important role in resisting additional loads when structural column is destroyed under unexpected loads.

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.

Moment rotation curves for semi rigid connections

2016 International Conference on Electrical, Electronics, and Optimization Techniques (ICEEOT), 2016
In the design of steel portal frames, we assume that the connections behave as it is pinned or rigid. Truly the connection would not behave as ideally pinned or ideally rigid. The connection falls between pinned and rigid, and it is known as semi-rigid. Change in the connection behavior changes the behavior of structure.

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.

Vibration analysis of frames with semi-rigid connections

Computers & Structures, 1984
Summary: Semi-rigid connections between members of frame structures are idealized as rotational and linear springs and the physical model representing each individual member is assumed to consist of a flexible beam with springs and dashpots attached at both ends.
