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.

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.

Review and Classification of Semi-Rigid Connections

2000
Most 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, 1951
The 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, 1995
This 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, 2009
Abstract 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, 2015
This 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, 2018
The 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.

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.
