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...
Optimum design of steel structures via differential evolution algorithm and application programming interface of SAP2000
Dedekargınoğlu, Özgür; Hasançebi, Oğuzhan; Department of Civil Engineering (2012)
The objective of this study is to investigate the use and efficiency of Differential Evolution (DE) method on structural optimization. The solution algorithm developed with DE is computerized into software called SOP2011 using VB.NET. SOP2011 is automated to achieve size optimum design of steel structures consisting of 1-D elements such as trusses and frames subjected to design provisions according to ASD-AISC (2010) and LRFD-AISC (2010). SOP2011 works simultaneously with the structural analysis and design ...
Modeling of the nonlinear behavior of semi-rigid connections in steel framed structures and its influence on three dimensional analysis of structural systems
Özel, Halil Fırat; Sarıtaş, Afşin; Department of Civil Engineering (2019)
In steel frame structures, introducing the nonlinear force-deformation behavior of frame members with flexible joints will show closer results to the actual behavior. In this thesis, a mixed formulation frame finite element is developed from a nonlinear force-based method that can include localized semi-rigid connection response. The formulation of the element uses the three-fields Hu-Washizu-Barr principle, where displacement shape function approximation is omitted with the use of a force-based approach. T...
Multi-objective performance based design optimization of steel structures
Eser, Hasan; Hasançebi, Oğuzhan; Yakut, Ahmet; Department of Civil Engineering (2021-5)
Seismic performance of structures designed in accordance with conventional force-based design (FBD) codes can vary significantly since (1) estimation and distribution of earthquake loads are based on initial stiffness of members and (2) force reduction factors are based on the rough assumption that all members will yield simultaneously. In recent decades, attempts to predict the seismic performance of structures resulted in the development of several guidelines for evaluation and rehabilitation of existing ...
Investigation of fracture behavior of steel/steel laminates
Şimşir, Mehmet; Öztürk, Tayfur; Department of Metallurgical and Materials Engineering (2004)
A study is carried out into fracture behavior of steel/steel laminates both experimentally and through finite element analysis (FEM). The laminates produced by hot pressing consisted of low carbon and medium carbon steels with two volume fractions; 0.41 and 0.81. Fracture toughness, JIC has been measured using partial unloading technique assuming a critical value of crack extension. The technique is initially applied to monolithic material and then to the laminates in crack divider orientation. Evaluation o...
