Buckling is a structural instability that load carrying capacity of a structural element may suddenly decrease. This sudden change in the load carrying capacity may cause catastrophic failures. Therefore, determination of the first buckling and collapse loads of structural elements is essential. FE analyses and structural testing are used to determine buckling characteristics of a structural element. However, in early design stages, FE analyses are time consuming and structural testing is costly. In this paper, artificial neural network tool is used to reduce computational effort to determine buckling loads of integrally stiffened structural panels in early design stages. Moreover, Latin Hypercube Sampling (LHS) methodology is used to reduce the number of required FE analyses to generate database that artificial neural network is based on. Mean errors and fit performance model results are compared to determine accuracy of the neural network results.

Determination of the Tensile Strength of Different Fiber Reinforced Concrete Mixtures
Ardoğa, Mehmet Kemal; Alam, Burhan; Yaman, İsmail Özgür (null; 2016-09-21)
Enhancing the tensile performance of concrete is the main advantage when fibers are added to this type of building materials. This improvement is usually measured through indirect methods like bending or split-tensile tests, in a way similar to normal concrete due to the absence of a standard tensile test for such purpose. Naturally, this type of tests does not determine the real tensile strength of the fiber reinforced concrete. Hence an important parameter, that is needed in modelling and designing proces...
Determination of Deformation Distributions in Welded Steel Tension Elements Using Digital Image Technigues
Sözen, Şahin; Güler, Murat (2010-09-27)
It is known that material properties, connection quality and manufacturing methods are among the important factors directly affecting the behavior of steel connections and hence steel structures. The possible performance differences between a fabricated connection and its computer model may cause critical design problems for steel structures. Achieving a reliable design depends, however, on how accurately the material properties and relevant constitutive models are considered to characterize the behavior of...
Modeling of shear yielding members for seismic energy dissipation
Sarıtaş, Afşin (2004-08-01)
Structural members yielding in shear are used in earthquake resistant systems, such as eccentrically braced steel frames and systems with passive energy dissipation devices, in a conscious effort to concentrate the energy dissipation capacity of the structure in components that can be repaired or replaced after a major earthquake. The simulation of the energy dissipation capacity of these components is important in the evaluation of the seismic response of these structural systems. This paper presents a new...
Evaluation of seismic response modification factors for steel frames by non-linear analysis
Bakır, Serhan; Yılmaz, Çetin; Department of Civil Engineering (2006)
In this study steel framing systems are investigated with regards to their lateral load carrying capacity and in this context seismic response modification factors of individual systems are analyzed. Numerous load resisting layouts, such as different bracing systems and un-braced moment resisting frames with various bay and story configurations are designed and evaluated in a parametric fashion. Three types of beam to column connection conditions are incorporated in evaluation process. Frames, designed acco...
Determination of Reliabffity Based New Load and Resistance Factors for Reinforced Concrete Structural Members
Firat, Fatih Kursat; Yücemen, Mehmet Semih (2014-07-01)
In this study, a procedure for the determination of new load and resistance factors for reinforced concrete structural members is proposed in view of the fact that the design practice in Turkey has changed after the occurrence of major earthquakes. The implementation of the procedure is carried out for the shear failure mode of reinforced concrete beams subjected to dead and live load combination. First, the statistical parameters for the quantification of uncertainties involved in the design variables are ...
