The analysis of horizontally curved, trapezoidal steel girders presents a variety of computational challenges. During the erection and construction stages before a concrete deck is available to form a closed section, these girders are weak in torsion and susceptible to warping. Considering the design of an entire bridge system, current design approaches favor the use of a grid analysis methodology. While the use of a grid analysis procedure offers the advantage of computational efficiency, it is unable to capture girder stresses and brace member forces with sufficient accuracy, particularly during the critical erection and construction stages. In this paper, we present an alternative analysis approach based on the finite element method. The developed software has been designed to be computationally efficient and easy to use for bridge designers.

Computer aided design of post-tensioned concrete reservoirs Oztorun, NK; Utku, M (Elsevier BV, 2002-11-01) A computer method based on the classical shell and plate theories is presented for the elastic analysis of cylindrical water tanks subjected to axisymmetrical loading and post-tensioning loads. A spherical dome or circular plate roof, cylindrical container, top and bottom ring beams together with a circular plate foundation are considered as possible components of a water tank in the flexibility formulation. Classical shell, plate, and ring beam theories are used to obtain flexibility coefficients. A comput...
CHAOTIC DYNAMIC ANALYSIS OF VISCOELASTIC SHALLOW SPHERICAL-SHELLS Karaesmen, Engin; ILERI, L; AKKAS, N (Elsevier BV, 1992-08-03) This paper investigates the dynamic behaviour of a shallow, viscoelastic, spherical shell under a harmonic excitation. The time evolutions of the response of the corresponding nonlinear dynamical system are described by the phase portraits and the bifurcation of the parameter dependent system is studied numerically so as to identify qualitative changes in the phase portrait. The viscoelastic shell, having more than one equilibrium configuration for some problem parameters, shows periodic and/or random-like ...
Optimum design of high-rise steel buildings using an evolution strategy integrated parallel algorithm Hasançebi, Oğuzhan; Kurç, Özgür (Elsevier BV, 2011-11-01) The present study addresses a parallel solution algorithm for optimum design of large steel space frame structures, in particular high-rise steel buildings. The algorithm implements a novel discrete evolution strategy optimization method to effectively size these systems for minimum weight according to the provisions of ASD-AISC specification and various practical aspects of design process. The multitasking environment in the algorithm rests on a master-slave model based parallelization of the optimization ...
VIBRATION OF MINDLIN PLATES SYMMETRICALLY COLUMN-SUPPORTED AT 4 POINTS AKSU, G (Elsevier BV, 1993-09-17) This paper deals with the free vibration characteristics of Mindlin plates that are symmetrically column-supported at four points. The finite difference technique, based on the energy approach, is used. The first lowest four natural frequency parameters are determined for various values of the finite area of the column supports. Detailed results are given for various values of relative thickness ratio and the effects of transverse shear deformation and rotary inertia are examined.
Guided stochastic search technique for discrete sizing optimization of steel trusses: A design-driven heuristic approach Azad, S. Kazemzadeh; Hasançebi, Oğuzhan; Saka, M. P. (Elsevier BV, 2014-04-01) This study presents a design-driven heuristic approach named guided stochastic search (GSS) technique for discrete sizing optimization of steel trusses. The method works on the basis of guiding the optimization process using the well-known principle of virtual work as well as the information collected during the structural analysis and design stages. The performance of the proposed technique is investigated through a benchmark truss instance as well as four real-size trusses sized for minimum weight accordi...
