A finite element parametric study on block shear failure of steel tension members

2004-11-01
Block shear is a limit state that should be accounted for during the design of steel tension members. Current design equations are not based on analytical findings and fail to predict failure modes of tested specimens. A study has been conducted to develop simple block shear load capacity prediction equations that are based on finite element analysis. Over a thousand nonlinear analyses were performed to identify the important parameters that influence block shear capacity. In addition, the effects of eccentric loading were investigated. Based on the parametric study block shear load capacity prediction equations were developed. The predictions of the developed equations were compared with the experimental findings and were found to provide estimates with acceptable accuracy.

A numerical study on block shear failure of steel tension members
Kara, Emre; Topkaya, Cem; Department of Civil Engineering (2005)
Block shear is a limit state that should be accounted for during the design of the steel tension members. This failure mechanism combines a tension failure on one plane and a shear plane on a perpendicular plane. Although current design specifications present equations to predict block shear load capacities of the connections, they fail in predicting the failure modes. Block shear failure of a structural connection along a staggered path may be the governing failure mode. Code treatments for stagger in a bl...
A numerical study on linear bifurcation web buckling of steel I-beams in the sidesway mode
Topkaya, Cem (Elsevier BV, 2006-06-01)
Sidesway web buckling is a limit state that needs to be considered during the design of steel I-beams subjected to transverse concentrated loads. Sidesway web buckling capacity equations presented by design codes offer estimates which are conservative to varying degrees. In this paper, the sidesway web buckling equations used by the AISC-LRFD specification are revisited. A parametric study based on finite element analysis has been conducted to identify the parameters that influence the web buckling of simpl...
A study on the stress-strain behavior of railroad ballast materials by use of parallel gradation technique
Kaya, Mustafa; Özkan, M. Yener; Department of Civil Engineering (2004)
The shear strength, elastic moduli and plastic strain characteristics of scaled-down ballast materials are investigated by use of the parallel gradation technique. Uniformly graded ballast materials chosen for the investigation are limestone, basalt and steel-slag. Steel-slag is a byproduct material of Eregli Iron and Steel Works, which is suitable to meet the durability test requirements as well as the electrical resistivity and the waste contaminants regulatory level. Conventional triaxial testing at a st...
A Finite element model for partially restrained steel beam to column connections
Köseoğlu, Ahmet; Sarıtaş, Afşin; Department of Civil Engineering (2013)
In the analyses of steel framed structures it is customary to assume the beam to column connections as either fully rigid which means that all moments are transferred from beam to column with negligible rotation or ideally pinned that resists negligible moment. This assumption is reasonable for some types of connections. However when considering steel connections such as bolted-bolted double web angle connections it can be seen that the behavior of these connections is in between the two extreme cases. Thus...
A numerical study on local buckling and energy dissipation of CHS seismic bracing
Kusyilmaz, Ahmet; Topkaya, Cem (Elsevier BV, 2011-08-01)
Seismic provisions for steel buildings present limiting width-thickness and slenderness ratios for bracing members, most of which were established based on experimental observations. A finite element study has been undertaken to evaluate these limits for pin-ended circular hollow section (CHS) steel braces. Uncertainties in modeling and quantification arise in the simulation of cyclic brace buckling. A finite element modeling procedure was developed and calibrated using existing experimental data. Sensitivi...
