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 block shear path are not exactly defined. A parametric study has been conducted and over a thousand finite element analyses were performed to identify the parameters affecting the block shear failure in connections with multiple bolt lines and staggered holes. The quality of the specification equations were assessed by comparing the code predictions with finite element results. In addition, based on the analytical findings new equations were developed and are presented herein.

A detailed analysis for evaluation of the degradation characteristics of simple structural systems Kurtman, Burak; Erberik, Murat Altuğ; Department of Civil Engineering (2007) Deterioration in the mechanical properties of concrete, masonry and steel structures are usually observed under repeated cyclic loading in the inelastic response range. Therefore such a behavior becomes critical when these types of structures are subjected to ground motions with specific characteristics. The objective of this study is to address the influence of degrading behavior on simple systems. The Structural Performance Database on the PEER web site, which contains the results of cyclic, lateral-load ...
A finite element parametric study on block shear failure of steel tension members Topkaya, Cem (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 eccent...
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 Comparative study on direct analysis method and effective length method in one-story semi-rigid frames Demirtaş, Afşin Emrah; Akyüz, Uğurhan; Department of Civil Engineering (2012) For steel structures, stability is a very important concept since many steel structures are governed by stability limit states. Therefore, stability of a structure should be assessed carefully considering all parameters that affect the stability of the structure. The most important of these parameters can be listed as geometric imperfections, member inelasticity and connection rigidity. Geometric imperfections and member inelasticity are taken into account with the stability method used in the design. At th...
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...
