A Comparative Study of AISC-360 and EC3 Strength Limit States

A study has been undertaken to evaluate the similarities and differences between the steel building design specifications used in the United States and Europe. Expressions for nominal strength presented in the AISC-360 Specification and the Eurocode 3 Specification were compared for fundamental limit states. In particular, rules for cross-section classification, tension members, compression members, I-shaped members subjected to flexure, 1-shaped members subjected to shear, and fasteners were studied. Results of the investigation revealed that, in general, both specifications provide nominal capacities that are close to each other. Significant differences were reported for some limit states such as flexure in I-shaped members with non-compact flanges, shear and lateral torsional buckling in I-shaped members, and bearing strength at bolt holes. In this paper, the details of the comparative study are presented along with observations that are useful for practicing engineers.


A Methodology for Optimal Layout Design of Pressure Cells for Concrete Faced Rockfill Dams
Arı, Onur; Yanmaz, Ali Melih (Springer Science and Business Media LLC, 2018-08-01)
In this study, a methodology for optimal layout design of pressure cells for concrete faced rockfill dams is developed. A representative dimensionless stress distribution model was formed for obtaining the magnitudes and location of different stress zones as a function of dam height. This information enabled development of a procedure for proper location and the number of pressure cells throughout the dam body. A vertical placement algorithm based on error minimization was first developed, which is followed...
Evaluation of steel building design methodologies: TS648,Eurocode 3 and LRFD
Zervent, Altan; Yılmaz, Çetin; Department of Civil Engineering (2009)
The aim of this study is designing steel structures with the same geometry, material and soil conditions but in the different countries, and comparing these designs in terms of material savings. According to three steel building codes, namely TS 648, LRFD, Eurocode 3, same structures with various stories (2, 4, 6, 8, and 10) are analyzed and designed. To calculate the design loads, Turkish Earthquake Code 2007 and Turkish Standard 498 (Design Load for Buildings) are utilized when TS 648 is applied. When LRF...
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...
Lateral buckling of overhanging crane trolley monorails
Ozdemir, Kerem Murat; Topkaya, Cem (Elsevier BV, 2006-07-01)
Lateral torsional buckling should be taken into account during the design of overhanging steel beams. One special type of overhanging beam is the crane trolley monorail. Lateral buckling of overhanging monorails under idealized loading and boundary conditions has been studied in the past using classical mathematical procedures. This paper aims to present a detailed investigation of overhanging monorails using finite element analysis. Effects of different loading and boundary conditions were studied in detai...
A Web based multi user framework for the design and detailing of reinforced concrete frames - beams
Anıl, Engin Burak; Kılıç, Özgür; Department of Civil Engineering (2009)
Structural design of reinforced concrete structures requires involvement of many engineers who contribute to a single project. During the design process engineers have to exchange wide variety of information. Unmanaged data exchange may result in loss of resources. Developing a data model and setting up protocols for the management of data related to various structural design tasks can help to improve the quality of the structural design. In this study, an object oriented data model was developed for reinfo...
