"Curved concrete box-girder bridges are widely applied in highway systems to enable traffic to move from one highway to another. The Akşemsettin Viaduct (termed A Viaduct in the current study) in Istanbul, Turkey, is a typical 11-span curved continuous bridge with a total length of 596.8 m. Located in the high seismicity zone, the A Viaduct exhibits complex seismic behaviour because varying ground motion inputs are expected to excite the bridge at different column/abutment foundations. This study investigates the seismic responses of the A Viaduct under different ground motion scenarios using nonlinear time history analyses (NTHAs). In particular, the software of OpenSees is used to develop a high-fidelity finite element model for the A Viaduct, from which seismic responses of multiple critical components are compared under uniform versus multiple support excitations. To supplement such comparisons, a literature survey is conducted regarding seismic damage to curved bridges, their soil-structure interaction effect, and the multi-support excitation scheme. Moreover, modelling considerations of key components are presented for the A Viaduct, and 6 representative groups of simulated ground motions are selected to capture the effects of site-specific surface topography and soil stratigraphy at the bridge site"--

Download Seismic Design and Assessment of Bridges Book in PDF, Epub and Kindle
The book focuses on the use of inelastic analysis methods for the seismic assessment and design of bridges, for which the work carried out so far, albeit interesting and useful, is nevertheless clearly less than that for buildings. Although some valuable literature on the subject is currently available, the most advanced inelastic analysis methods that emerged during the last decade are currently found only in the specialised research-oriented literature, such as technical journals and conference proceedings. Hence the key objective of this book is two-fold, first to present all important methods belonging to the aforementioned category in a uniform and sufficient for their understanding and implementation length, and to provide also a critical perspective on them by including selected case-studies wherein more than one methods are applied to a specific bridge and by offering some critical comments on the limitations of the individual methods and on their relative efficiency. The book should be a valuable tool for both researchers and practicing engineers dealing with seismic design and assessment of bridges, by both making the methods and the analytical tools available for their implementation, and by assisting them to select the method that best suits the individual bridge projects that each engineer and/or researcher faces.

Download Experimental and Analytical Investigation on the Behavior of Continuous Box Girder Bridges Book in PDF, Epub and Kindle
Continuous curved box girder bridges are increasingly being used in metropolitan large cities particularly as flyovers and as entrance and exit ramps for highspeed freeways. The purpose of this investigation is to examine the static response of continuous curved box girder bridges subjected to various specified OHBD loadings. The prototype structure that was selected for this model study is the Cyrville road Queensway overpass located in the east end of Ottawa. The structure was built in 1973 and designed according to ASHTO design truck load HS20-44 by the Ministry of Transportation and Communication. The bridge is 102.4 meters long, 12.8 meters wide, and consists of two spans with 16.8$\sp\circ$ horizontal angle of curvature between the end supports. Its cross section consists of four contiguous cells with a depth of 1.83 meters. As for the diaphragms, two prestressed diaghragms are placed at the extreme end supports and one is placed over the middle support.
