Özet

Contemporary design codes necessitate ways to determine realistic behavior of structures. Nonlinear analysis is used extensively for design purpose since strength and stability of the whole structure can be represented. In nonlinear analysis, some assumptions for stability issues are made to ensure the unrestricted plastic redistribution of moments between the frame members. In this study, a methodology is presented for improving nonlinear analysis of steel frames accounting lateral torsional buckling. Analysis results revealed that considering lateral torsional buckling in nonlinear analysis has decreased load carrying capacity severely and underlined the importance of structural stability.
