In this study, dynamic effects on high speed railway bridges under moving traffic are investigated. Within this context, the clear definition of the possible dynamic effects is provided and the related studies that exist in literature are investigated. In the light of those studies, analytical procedures that are defined to find the critical dynamic responses such as deflections, accelerations and resonance conditions are examined and a MatLab programming language is written to obtain the responses for different train loading and velocity values. The reliability of the written program is conformed by comparing the results with the related studies in literature. In addition to the analytical procedures, the approaches in the European standards concerning the dynamic effects of railway traffic are defined. A case study is investigated for a bridge that is in the scope of the Ankara-Sivas High Speed Railway Project. The related bridge is modeled by using finite element program, SAP2000 according to the definitions that are stated in European standards. The related high speed railway bridge is analysed with a real train which is French TGV together with the HSLM trains that are defined in Eurocode and the results obtained are compared with each other. This study also includes the analysis of the bridges performed for 7 different stiffness and 3 different mass values to determine the parameters affecting dynamic behaviour.

Seismic response of multi-span highway bridges with two-column reinforced concrete bents including foundation and column flexibility Yılmaz, Taner; Caner, Alp; Department of Civil Engineering (2008) Seismic design of highway bridges has improved as a result of the experience gained from large earthquakes of the last thirty years. Ductility demand and reserved capacity are extremely important response measures used in new bridge designs to assess target damage levels. However, the application of practical design approaches specified in bridge design codes is not well-defined for bridges over flexible foundations. Within the scope of this research, thirty two bridge models having varying column aspect ra...
Vertical ground motion influence on seismically isolated & unisolated bridges Rehanoğulları, Naim Eser; Akyüz, Uğurhan; Department of Civil Engineering (2010) In this study influences of vertical ground motion on seismically isolated bridges were investigated for seven different earthquake data. One assessment of bearing effect involves the calculation of vertical earthquake load on the seismically isolated bridges. This paper investigates the influence of vertical earthquake excitation on the response of briefly steel girder composite bridges (SCB) with and without seismic isolation through specifically selected earthquakes. In detail, the bridge is composed of ...
Impact of passanger comfort level on design of short-span composite steel i-girder high speed railroad bridges Şentürk, Tolga; Caner, Alp; Department of Civil Engineering (2009) In globalizing world, increase in demand for high speed rail travel requires comfortable ride over bridges while maintaining an economical design. These bridges either have composite steel I-girders, prestressed precast I or box girder superstructures. The span lengths can reach up to 40 meters. If frequency of wheel load pass at a point on bridge matches with one the critical frequencies of the structure, excessive vibration can developed both at the train and the bridge even if the structure is structural...
Cost estimation of trackworks of light rail and metro projects Öztürk, Erhan; Gündüz, Murat; Department of Civil Engineering (2009) The main objective of this work is to develop models using multivariable regression and artificial neural network approaches for cost estimation of the construction costs of trackworks of light rail transit and metro projects at the early stages of the construction process in Turkey. These two approaches were applied to a data set of 16 projects by using seventeen parameters available at the early design phase. According to the results of each method, regression analysis estimated the cost of testing sample...
Seismic retrofitting of highway bridges in Illinois using friction pendulum seismic isolation bearings and modeling procedures Dicleli, Murat (Elsevier BV, 2003-07-01) In this paper, the economical and structural efficiency of friction pendulum bearings (FPB) for retrofitting typical seismically vulnerable bridges in the State of Illinois is studied. For this purpose, a bridge was carefully selected by the Illinois Department of Transportation (IDOT) to represent typical seismically vulnerable bridges commonly used in the State of Illinois. A comprehensive structural model of the bridge was first constructed for seismic analysis. An iterative multi-mode response spectrum ...
