In this paper, a force-based three-dimensional frame finite element formulation with spread of inelasticity through the element and localized nonlinear semi-rigid connections is developed. The proposed model utilizes Euler-Bernoulli beam theory assumptions, and adopts fiber discretization of monitored sections along element length and section depth for the spread of inelasticity in order to capture axial force and biaxial bending moment interaction. Defining any type of semi-rigid either linear or nonlinear connection behavior along element length does not necessitate any increase in number of degrees of freedom. The element is modelled with option of capturing nonlinear geometric effects. The proposed element is designated for the biased analysis of steel structures, since considering the presence of beam to column semi-rigid connections through analyses provides true behavior. The formulated element can also consider the presence of any type of connection that may be present in a steel structure; such as beam to column, column base, brace end connections. Specific to this study, moment-rotation response of beam to column connections is implemented for both the strong axis and weak axis bending directions. Numerical examples are considered to verify the results obtained from the developed finite element models with regards to other available structural analysis programs.

A 2d Frame Element Taking Into Account Semi-Rigidity At Column Bases, Brace Ends Beam To Column Connections In Steel Structures
Özel, Halil Fırat; Sarıtaş, Afşin (null; 2017-10-05)
In this paper, a force-based 2D frame element formulation with spread of inelasticity through the element and localized semi-rigid connections at beam, brace and column base regions is presented. Inelasticity along member lengths is captured through fiber discretization of monitoring sections; furthermore, defining any type of semi-rigid connection along element length does not require introduction of additional nodes and degrees of freedom to the system. An accurate shear correction coefficient for wide fl...
Modeling of the nonlinear behavior of steel framed structures with semi rigid connections
Sarıtaş, Afşin; Özel, Halil Fırat (null; 2015-07-21)
A mixed formulation frame finite element with internal semi-rigid connections is presented for the nonlinear analysis of steel structures. Proposed element provides accurate responses for spread of inelasticity along element length by monitoring the nonlinear responses of several crosssections, where spread of inelasticity over each section is captured with fiber discretization. Each material point on the section considers inelastic coupling between normal stress and shear stress. The formulation of the ele...
A Three dimensional mixed formulation nonlinear frame finite element based on hu-washizu functional
Soydaş, Ozan; Sarıtaş, Afşin; Department of Civil Engineering (2013)
A three dimensional nonlinear frame finite element is presented in this analytical study by utilizing Hu-Washizu principle with three fields of displacement, strain and stress in the variational form. Timoshenko beam theory is extended to three dimensions in order to derive strains from the displacement field. The finite element approximation for the beam uses shape functions for section forces that satisfy equilibrium and discontinous section deformations along the beam. Nonlinear analyses are performed by...
Three dimensional delamination analysis in composite open hole tensile specimens with cohesive zone method
Bartan Kumbasar, Busra; Acar, Bulent; Kayran, Altan (American Institute of Aeronautics and Astronautics Inc, AIAA; 2016-01-01)
In this article, finite element analyses (FEA) are conducted for delamination analysis in composites using three dimensional (3D) solid cohesive elements. The analyses are validated with tests. The main objective of the study is to predict damage initiation and propagation utilizing three dimensional (3D) solid cohesive elements in an implicit finite element analysis framework. First study is conducted for Double Cantilever Beam (DCB) and End Notch Flexure (ENF) specimens in ABAQUS with cohesive zone method...
Finite element modeling approaches and comparative study on the nonlinear behavior of steel shear-links
Kızıldağ, Yaşam; Sarıtaş, Afşin; Department of Civil Engineering (2013)
This study deals with the finite element modeling of the nonlinear behavior of shear links under various loading and boundary conditions. Shear-links are the most important part of an eccentrically braced steel frame system, and provide fuse in terms of reducing the forces acting on the rest of the members such as columns and braces in the framing system. Shear-links are designed for dissipation of large amounts of energy in case of overloading; therefore construction of buildings with eccentrically braced ...
