In highway bridge construction, composite curved girder bridges are becoming more popular recently. Reduced construction time, long span coverage, economics and aesthetics make them more popular than the other structural systems. Although there exist some methods for the analysis of such systems, each have shortcomings. The use of Finite Element Method (FEM) among these methods is limited except in the academic environments. The use of commercial FEM software packages in the analysis of such systems is cumbersome as it takes too much time to form a model. Considering such problems a computational software was developed called UTRAP in 2002 which analyzes bridges for construction loads by taking into account the early age deck concrete. As the topic of this thesis work, this program was restructured and new features were added. In the following thesis work, the program structure, modeling considerations and recommendations are discussed together with the parametric studies.

Experimental and numerical investigation of the wind effects on long span bridge decks
Iman, Ashtiani Abdi; Uzol, Oğuz; Kurç, Özgür; Department of Aerospace Engineering (2011)
Long span bridges are susceptible to wind. Hence it is important to study their wind-induced vibrations to avoid any probable structural failures. In this thesis, the results of an experimental and computational investigation of the aerodynamic characteristics of trapezoid bridge deck cross-sections with three different aspect ratios (10, 12 and 15) and four different side angles (75º, 60 º, 45 º and 30 º) are analyzed and presented. The flow around rigid fixed bridge deck models is investigated to obtain t...
Quantitative approach to rapid seismic evaluation of slab-on-girder steel highway bridges
Dicleli, Murat (1996-01-01)
A quantitative approach follows for developing a methodology for the rapid seismic evaluation and ranking of slab-on-girder steel highway bridges. In the development of this methodology, analytical expressions are introduced to calculate the seismically induced forces and displacements in bridge components, first assuming that damage to bearings is not acceptable and then removing this constraint. In the latter case, the superstructure is assumed to become unrestrained and slide on its supports. The seismic...
Development of a safetyinspection methodology for river bridges
Berk, Aysu; Yanmaz, Ali Melih; Department of Civil Engineering (2006)
River bridges get damaged or even collapse because of various reasons, such as development of adverse hydraulic conditions during severe floods, disastrous earthquakes, deficiencies in structural and geotechnical design, material deficiencies, or other unexpected external factors. Failure of service at vital lifelines, bridges, can lead to loss of several lives and properties, traffic disruption, and/or deficiencies in daily usage. Existing structures should be monitored periodically for decision-making and...
Development of a graphical user interface for composite bridge finite element analysis
Güven, Deniz; Topkaya, Cem; Department of Civil Engineering (2007)
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 b...
SEISMIC RETROFIT OF OLD BRIDGES WITH SEISMIC ISOLATION
Caner, Alp; Shaban, Nefize (null; 2017-01-05)
A standard highway bridge has usually multi simple spans supported over piers by elastomeric bearings in Turkey. The bearings usually do not provide a positive connection but in contact with girder and pier by only gravitational forces. In this study, a model test bridge of about ½ scale have been shaken under low to moderate earth quakes to determine the change in response of the bridge with different seismic isolation configurations. Three configurations of bearings are elastomeric bearings, lead core bea...
