    Geometrically nonlinear analysis of plane frames composed of flexibly connected members
    (Techno-Press, 2013) Gorgun, H.
    Beam-to-column connections behaviour plays an important role in the analysis and design of steel and precast concrete structures. The paper presents a computer-based method for geometrically nonlinear frames with semi-rigid beam-to-column connections. The analytical procedure employs modified stability functions to model the effect of axial force on the stiffness of members. The member modified stiffness matrix, and the modified fixed end forces for various loads were found. The linear and nonlinear analyses were applied for two planar steel structures. The method is readily implemented on a computer using matrix structural analysis techniques and is applicable for the efficient nonlinear analysis of frameworks.

    Geometrically nonlinear analysis of plane frames with semi-rigid connections accounting for shear deformations
    (Techno-Press, 2012) Gorgun, H.; Yilmaz, S.
    The behaviour of beam-to-column connections plays an important role in the analysis and design of steel structures. A computer-based method is presented for nonlinear steel frames with semirigid connections accounting for shear deformations. The analytical procedure employs transcendental stability functions to model the effect of axial force on the stiffness of members. The member stiffness matrix, and the fixed end forces for various loads were found. The nonlinear analysis method is applied for three planar steel structures. The method is readily implemented on a computer using matrix structural analysis techniques and is applicable for the efficient nonlinear analysis of frameworks.

    Optimum design of geometrically non-linear steel frames with semi-rigid connections using a harmony search algorithm
    (Techno-Press, 2009) Degertekin, S. O.; Hayalioglu, M. S.; Gorgun, H.
    The harmony search method based optimum design algorithm is presented for geometrically non-linear semi-rigid steel frames. Harmony search method is recently developed metaheuristic algorithm which simulates the process of producing a Musical performance. The optimum design algorithm arms at obtaining minimum weight steel ftarnes by selecting from standard set ol'steel Sections Such ZIS E-uropeall wide flange beams (HE sections). Strength constraints of Turkish Building Code flor Steel Structures (TS648) specification and displacement constraints were used in the optimum design formulation. The optimum design algorithm takes into account both the geometric non-linearity of the frame members and the semi-rigid behaviour of the be,beam-to-column Connections. The Frye-Morris polynomial model is used to calculate the momentrotation relation of beam-to-column connections. The ronustness of harmony search algorithm, ill comparison with genetic algorithms, is verified with two benchmark examples. The comparisons revealed that tile harmony search algorithm yielded not Only weight steel frames but also required less computational effort for the presented examples.
