Finite element modeling of block shear failure in coped steel beams

Block shear is a potential failure mode that is encountered in the connection regions of coped steel beams. Limited experimental studies completed so far have shown that the block shear failure in coped steel beams is a complex phenomenon, which is highly dependent on the number of bolt lines. In this paper, the use of the finite element method in predicting the block shear failure load was studied by making comparisons with experimental findings. The effects of numerical modeling details on load capacity predictions were investigated. In light of these investigations, a finite element analysis methodology has been developed and used to conduct a parametric study. Simplified load capacity prediction equations were developed based on the results of the parametric study and are presented herein.


Finite element implementation of a model to estimate the permanent strain of cyclically-loaded soil
Babaoğlu, Muhittin; Erdoğan, Sinan Turhan; Department of Civil Engineering (2020)
In vast majority of geotechnical structures such as monopile or strip foundation, which are subjected to repeated loading, long-term resilience of the structures is directly related with the behavior of granular materials subjected to cyclic loading. Repeatedly loaded structure distributes stress to soil that surrounds the structure. When granular materials are exposed to cyclic loading, plastic strain occurs despite the applied stress is less than plastic yield, which results to residual settlement. This t...
Finite element analysis of composite laminates subjected to axial and transverse loading
Baskın, İsmail Cem; Akyüz, Uğurhan; Department of Civil Engineering (2004)
This thesis focuses on the investigation of behavior of thick and moderately thick laminates under transverse and horizontal loading for different boundary conditions and configurations. An efficient finite element solution is proposed for analyzing composite laminates. Based on a combination of composite theory and 3-D Elasticity Theory, a 3-D finite element program is developed in MATLAB for calculating the stresses, strains and deformations of composite laminates under transverse and/or horizontal loadin...
Block shear failure of gusset plates with welded connections
Topkaya, Cem (2007-01-01)
The mechanics of block shear failure in bolted connections has been studied extensively in the past. Current literature, however, lacks experimental evidence of the possibility of block shear failure in welded connection details. This study reports on the experimental testing of 11 welded gusset plate specimens which are subjected to tension. In the experimental program, the effects of connection geometry and weld group configuration were investigated. Test results revealed that block shear is a potential f...
An Accurate modeling approach for calculating the vibration characteristics of steel framed structures with semi rigid connections
Özel, Halil Fırat; Sarıtaş, Afşin (null; 2015-07-01)
Vibration characteristics of steel framed structures are affected by the presence of semi-rigid connections. In this study, a mixed formulation frame finite element is developed from force method, where the variational form of the element bases on the use of three-fields Hu-Washizu-Barr principle. 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 an...
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 ...
