Review and Classification of Semi-Rigid Connections
2000Most design engineers assume the behavior of their building connections either as perfectly pinned or as completely fixed elements. This simplification results in an inaccurate prediction of frame behavior. Full-scale experiments are generally necessary to describe actual behavior of these connections.

Elastic Restraint Equations for Semi-Rigid Connections
Transactions of the American Society of Civil Engineers, 1951The restraining effects of semi-rigid, girder-column connections have received considerable attention within recent years in both the United States and Great Britain.

Expanded database of semi-rigid steel connections
Computers & Structures, 1995This paper expands the existing database of semi-rigid steel connections at Purdue University by including additional test data on header-plate and seat-angle, and double-web and seat-angle connections. The experimental moment rotation curves are also compared with several analytical models describing these curves.

Energy dissipation characteristics of semi-rigid connections
Journal of Constructional Steel Research, 2009Abstract This study presents the energy dissipation characteristics of semi-rigid connections obtained from 48 full-scale cyclic tests. The energy calculation was performed on the hysteresis loops obtained from the experimental data in which the area under the outer loop of each hysteresis was calculated.

Identification of Semi-Rigid Connections from Stationary Statistical Moments
Civil-Comp Proceedings, 2015This paper presents a procedure for the identification of semi-rigid end connections of beam/column elements in frame structures. The technique relies on an explicit relationship between second order moments of the nodal stationary response under white noise and element end flexibilities.

Behavior Factor of Dual Systems with BRBs and Semi-Rigid Connections
Key Engineering Materials, 2018The use of BRBs into a typical European building with braced structure, whereby all the beam-to-column connections are perfectly pinned, may be low effective. In fact, these structures are low-redundant and prone to develop soft story collapse mechanisms.

Semi-rigid Steelwork Connections
This thesis sets out to assess the stiffness of typical fin plate steelwork connections. The classification of joints as pinned, semi-rigid or fixed is described and the different models of moment-rotation relationship are explained. Eurocode treatment of steelwork connections is assessed with particular emphasis on joint stiffness.openaire +1 more source
Semi-rigid connection modeling for steel frameworks
Structural Engineering and Mechanics, 2010This article provides a discussion of the mathematic modeling of connections for designing and qualifying structures, systems, and components subject to monotonic or cyclic loading. To characterize the force-deformation behavior of connections under monotonic loading, a review of the Ramberg-Osgood, Richard-Abbott, and Menegotto-Pinto models is ...

Effective Length of Columns with Semi-Rigid Connections
Engineering Journal, 1976The effective length of a column depends on the boundary conditions at the ends of its unbraced length. In a framed structure, the boundary conditions depend on the stiffness of the beams framed to the column. Design guides available for determining the effective length are provided for cases where beams are rigidly framed to the column and have their ...
