In this paper, a mixed formulation frame finite element with semi-rigid connections is developed. Consistent mass matrix of the element is obtained such that determination of vibration frequencies of members with varying geometry and material distribution as well as the presence of semi-rigid connections at any section on the element is accurately captured without the need to specify displacement shapes. An accurate shear correction coefficient for wide flange sections is taken into account in order to get closer match with exact solutions. Numerical examples on a portal frame and a multi-story steel moment resisting frame verify the accuracy of proposed element with and without semi-rigid connections

Three dimensional frame element formulation for nonlinear analysis of semi rigid steel structures
Özel, Halil Fırat; Sarıtaş, Afşin; Karakaş, Zafer (null; 2016-09-21)
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...
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 ...
Finite element modeling of electromagnetic radiation
Yılmaz, Asım Egemen; Kuzuoğlu, Mustafa; Department of Electrical and Electronics Engineering (2007)
In this thesis, quadratic hexahedral edge elements have been applied to the three dimensional for open region electromagnetic scattering problems. For this purpose, a semi-automatic all-hexahedral mesh generation algorithm is developed and implemented. Material properties inside the elements and along the edges are also determined and prescribed during the mesh generation phase in order to be used in the solution phase. Based on the condition number quality metric, the generated mesh is optimized by means o...
Finite Element Modeling of MEMS Piezoelectric Energy Harvester
Beker, L.; Muhtaroglu, A.; Özgüven, Hasan Nevzat; Külah, Haluk (2012-06-21)
This paper reports an improved method for modeling and optimization of a MEMS piezoelectric energy harvester (PEH) within desired frequency range with maximum voltage output using finite element method (FEM). Piezoelectric analysis is not trivial due to the difference between the information supplied by manufacturer and the inputs required by FEM tool. A translation procedure using piezoelectric constitutive equations is proposed to address this problem. A parametric MEMS PEH design is optimized with given ...
Finite element modeling of beams with functionally graded materials
Gürol, Tolga; Sarıtaş, Afşin; Department of Civil Engineering (2014)
In this thesis a new beam element that is based on force formulation is proposed for modeling elastic and inelastic analysis of beams with functionally graded materials. The attempt of producing functionally graded materials (FGM) arose from mixing two materials in such a way that both of them preserve their physical, mechanical and thermal properties most effectively. FGM shows a gradation through the depth from typically a metallic material such as steel or aluminum at one face of the beam’s section depth...
