Highway bridges are frequently constructed as simple span structures with steel or concrete girders and a cast-in-place concrete deck, spanning from one pier to another. At each end of the simple span deck, a joint is provided for deck movement due to temperature, shrinkage, and creep. Bridge deck joints are expensive and pose many problems with regard to bridge maintenance. Elimination of deck...

River bridge piers may collapse due to the local scour around their foundations. It is known that an effect of three-dimensional flow field develops near pier and geometric complexity a non-cylindrical may, correspondingly, increase process. also various devices be used as countermeasures. This manuscript explores use bed sill countermeasure for at complex compound array piles, pile cap, two in...

Transported large wood (LW) in rivers may block at river infrastructures such as bridge piers and pose an additional flood hazard. An improved process understanding of LW accumulations is essential for a risk assessment. Therefore, we conducted field study the River Glatt Zurich (Switzerland) to analyze accumulation single logs circular pier evaluate results previous flume experiments with resp...

The present analysis focuses on the investigation of two-dimensional flow passing a bridge pier nearby splitter plate in different regimes laminar flow. is T-shaped and two cases have been studied based form relative to pier. implemented for steady incompressible water an open channel. current study deals with velocity vectors, drag coefficients, lift skin friction. vector gave good indicator a...

Continuous rigid frame bridge is a common type of bridge in California, where is a seismically active areas. Main structural features of the bridge, including asymmetry, hinge structure, concretion of girder and piers affect the seismic response of the bridge significantly. In order to evaluate the safety of the bridge under earthquake, the nonlinear models of girder, limiting steels in hinge, ...

Flow in river bends is associated with generation of secondary flows that leads to a rather complicated flow pattern around bridge piers located the bend. In this study, patterns rectangular and oblong models collar at 90o angle 180-degree sharp bend an experimental plume were investigated. The 3D velocity data collected using Vectrino velocimeter. results indicated presence pier caused more in...
