Development of a graphical user interface for composite bridge finite element analysis

Güven, Deniz
Curved bridges with steel/concrete composite girders are used frequently in the recent years. Analysis of these structural systems presents a variety of challenges. Finite element method offers the most elaborate treatment for these systems, however its use is limited in routine design practice due to modeling requirements. In recent years, a finite element program named UTrAp was developed to analyze construction stages of curved/straight composite bridges. The original Graphical User Interface could not be used with the modified computation engine. It is the focus of this thesis work to develop a brand new Graphical User Interface with enhanced visual capabilities compatible with the engine. Pursuant to this goal a Graphical User Interface was developed using C++ programming language together with OPENGL libraries. The interface is linked to the computational engine to enable direct interaction between two programs. In the following thesis work the development of the GUI and the modifications to the computational engine are presented. Moreover, the analysis results pertaining to the newly added features are checked against analytical solutions and recommendations presented in design specifications.


Behavior of curved steel trapezoidal box-girders during construction
Topkaya, Cem; Frank, KH (Elsevier BV, 2004-05-01)
In recent years, steel, trapezoidal box-girders for curved highway interchanges have been used extensively. For these structural systems, the majority of the steel girder cross-sectional stresses occur during the concrete pouring sequence. This paper describes a comprehensive study on the behavior of curved girders during construction. Data collected for the current research shows significant differences between the measured and predicted quantities, particularly for later pours. An overview of the steel-co...
Evaluation of Top Flange Bracing Systems for Curved Box Girders
Topkaya, Cem; Williamson, Eric B. (American Society of Civil Engineers (ASCE), 2005-11-01)
In recent years, steel trapezoidal box girders for curved highway interchanges have become popular. For these bridge systems, significant steel girder cross-sectional stresses occur during the concrete casting sequence. To help resist construction loads, a lateral truss system is installed at a level close to the top flanges to form a "pseudo-closed" section, which has a higher torsional stiffness than an open U-section. Several recent incidents, ranging from the buckling of individual bracing members to th...
Optimum design of double-layer grid systems: comparison with current design practice using real-life industrial applications
Aydıncılar, Yılmaz; Hasançebi, Oğuzhan; Department of Civil Engineering (2010)
Double-layer grid systems are three-dimensional pin-jointed structures, which are generally used for covering roofs having large spans. In this study, evolution strategies method is used to optimize space trusses. Evolution strategies method is a type of evolutionary algorithms, which simulate biological evolution and natural selection phenomenon to find the best solution for an optimization problem. In this method, an initial population is formed by various solutions of design problem. Then this initial po...
Development of a physical theory model for the simulation of hysteretic behavior of steel braces
Çalık, Ertuğrul Emre; Dicleli, Murat; Department of Engineering Sciences (2007)
Bracing members are considered to be effective earthquake-resistant elements as they improve the lateral strength and stiffness of the structural system and contribute to seismic energy dissipation by deforming inelastically during severe earthquake motions. However, the cyclic behavior of such bracing members is quite complex because it is influenced by both buckling and yielding. This thesis presents simple but an efficient analytical model that can be used to simulate the inelastic cyclic behavior of ste...
Simple models for drift estimates in framed structures during near-field earthquakes
Erdoğan, Burcu; Gülkan, Polat; Department of Civil Engineering (2007)
Maximum interstory drift and the distribution of this drift along the height of the structure are the main causes of structural and nonstructural damage in frame type buildings subjected to earthquake ground motions. Estimation of maximum interstory drift ratio is a good measure of the local response of buildings. Recent earthquakes have revealed the susceptibility of the existing building stock to near-fault ground motions characterized by a large, long-duration velocity pulse. In order to find rational so...
