This book was released on 2013-11-27 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientific Study from the year 2013 in the subject Engineering - Civil Engineering, grade: -, University of Weimar, course: Cable Stayed Bridges, language: English, abstract: In this research, many models of a cable stayed bridge were generated using ABAQUS finite element commercial software for the purpose of proceeding with nonlinear design optimization on the shape and topology of the structure. The cable stayed bridge models in all cases are with a constant length and width for the deck, also the pylons height under and above the deck is constant, but the shape of stay cables arrangement varies to three main famous arrangements which are Fan, Semi harp and Harp.In addition to change in the pylons shape which are three known shapes Double out, Single Center and Single inclined out, and it is worthy to mention that in all cases of the shape optimization of the pylons , the stay cables arrangements are Fan style, andby governing computational nonlinear optimization process on the finite element models in all cases of shape and topology optimization through using static general step for analysis and a certain meshing type with global seeding size for the Beam elements, with a fixed and pinned boundary conditions for the deck supports and fixed boundary for the pylons.Concentrated static loads assigned on the same positions on the deck for all models cases. A numerical optimization and graphical simulation of the results were used to determine many responsesin the model cases which areReactions, Deflections and Mises stresses in the structural models of the cable stayed bridge, especially at the deck, pylons and the stay cables which are the main components of the structure, also the same step in the deck and pylons supportshas been done for optimization outputs. It is apparent and clear that the cable stayed model with the Fan arrangement of the stay cables showed efficiency and the best topological model case for the structural design optimization that involved a safe, robust, rigid, and safe for the design of cable stayed bridges. The pylon shape with double out case was the best design situation compared with the other two models single center and single inclined out shapes, this point was obvious in the reactions, deflections and Mises stresses for the deck supports and the deck itself, and as a result the Double out with a Fan shape arrangement of the cable stays is the best model for the design of cable stayed bridges to resist the static loads.

Available in PDF, EPUB and Kindle. Book excerpt: Fourteen years on from its last edition, Cable Supported Bridges: Concept and Design, Third Edition, has been significantly updated with new material and brand new imagery throughout. Since the appearance of the second edition, the focus on the dynamic response of cable supported bridges has increased, and this development is recognised with two new chapters, covering bridge aerodynamics and other dynamic topics such as pedestrian-induced vibrations and bridge monitoring. This book concentrates on the synthesis of cable supported bridges, suspension as well as cable stayed, covering both design and construction aspects. The emphasis is on the conceptual design phase where the main features of the bridge will be determined. Based on comparative analyses with relatively simple mathematical expressions, the different structural forms are quantified and preliminary optimization demonstrated. This provides a first estimate on dimensions of the main load carrying elements to give in an initial input for mathematical computer models used in the detailed design phase. Key features: Describes evolution and trends within the design and construction of cable supported bridges Describes the response of structures to dynamic actions that have attracted growing attention in recent years Highlights features of the different structural components and their interaction in the entire structural system Presents simple mathematical expressions to give a first estimate on dimensions of the load carrying elements to be used in an initial computer input This comprehensive coverage of the design and construction of cable supported bridges provides an invaluable, tried and tested resource for academics and engineers.

Available in PDF, EPUB and Kindle. Book excerpt: As the spans of cable-stayed bridges increase, the degree of nonlinearity of structural response increases markedly. For future spans greater than (say) 800 m, existing three-dimensional software then becomes very time consuming and costly, and a finite strip approach becomes more attractive and preferable. An improved finite strip method using two types of longitudinal shape functions is developed in this paper for the analysis of girders of such bridges. The nonlinearities due to sag and angle change of the cables are taken into account by means of catenary theory. The substructuring technique and the modified Newton-Raphson iteration method are used for noninear solutions. A number of numerical examples are given to show the accuracy and efficiency of this method.

Book excerpt: ABAQUS Finite Element Analysis software is used to apply computational design optimization process on cable stayed bridge models in relation with shape and topology of the structure. Three styles of stay cables arrangements and three types of pylons are created for structural optimization. The aim is to identify the most efficient design models with a robust, serviceable, safe and stiffness against oscillation and failure due to self weight and external loads

This book was released on 2008 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Initial shape analysis of cable-stayed bridges during construction by cantilever method is under investigation in this study. The main objective is to improve the calculation procedure, given in recent studies, for finding the initial shape of such bridges. A finite element computational algorithm is formulated for the analysis of the bridges at each construction stage using substructuring technique. Forward process analysis in accordance with the actual construction sequence is performed and geometric nonlinearity due to the cable sag is taken into account. Successive over-relaxation (SOR) technique is employed to accelerate the convergence rate of the shape iteration in finding the initial shape of the bridges. Four different types of cable-stayed bridges are examined as case studies. The results from these case studies show that the convergence rate of the shape iteration, for finding the initial shape of the bridges during construction, can be improved by using the SOR technique. However, the optimum value of the over-relaxation factor cannot exactly be determined since it varies from problem to problem and is often determined empirically. Nevertheless, appropriate over-relaxation factor found in the case studies ranges between 1.1 and 1.9. For the bridges with a small number of cables, the value of the over-relaxation factor from 1.1 to 1.4 may be used. A large value of the over-relaxation factor tends to be suitable for the bridges with a large number of cables and significant improvement of the convergence of the shape iteration can be achieved especially for nonlinear analysis.
