Abstract: Long-span, prestressed concrete, box-girder bridges are haunched and have a span-to-depth ratio of 15 to 20 at the piers. This leads to slender webs, particularly for bridges built with high performance concrete. For girders ...

Abstract: An analysis is described that models the behavior of planar prestressed concrete cable‐stayed bridges up to failure taking into account geometric and material nonlinearities. The geometric nonlinearities arise from cable ...

Abstract: A computer method is presented for the analysis of cable‐stayed prestressed concrete bridges for time‐dependent effects of creep and shrinkage of concrete and relaxation of prestressing steel. Nonlinear behavior due to ...

Abstract: A new method of construction for multispan cable‐stayed bridges is described. This method is one of several options developed for construction of the 13‐km‐long fixed link across the Northumberland Strait connecting Prince ...

Abstract: Temperature distribution in composite box girder bridges is predicted from the diurnal variation of the solar radiation to which the structure is exposed. Parametric studies are conducted in order to find the extreme ...

Abstract: The analysis to compute prestress loss and the stress redistribution in concrete and nonprestressed reinforcement due to the time‐dependent effects of creep, shrinkage, and relaxation of prestressed steel, in partially ...
