In this paper, a series of numerical experiments are carried out on the anti-scour device combined with perforated baffle and ring-wing plate. addition, optimal dimensions location obtained: The ratio is S = 20%, distance from center bridge pier L 2d (d diameter pier), plate located at H 1/3h (h water depth). To verify effect device, scour characteristics flow field further investigated. Compar...

THE CAUCHY DOUBLE ALTERNANT AND DIVIDED DIFFERENCES WENCHANG CHU Dedicated to my friend Pier Vittorio Ceccherini for his 65th birthday Abstract. As an extension of Cauchy’s double alternant, a general determinant evaluation formula is established. Several interesting determinant identities are derived as consequences by means of divided differences.

self-centering pier (scp) has been viewed as a remarkable accomplishment which is able to sustain major lateral loading with reduced structure damage in seismic engineering. stiffness deterioration observed in experiment is vital for the seismic performance of self-centering concrete pier. in this contribution, the associated stiffness deterioration with respect to the structural damage is mode...
scoure is the removal of particle sediment which results variation of flow pattern. local scour is considered as one of the reasons of instability and ultimately failure of bridges.therefore, proposing some controlling methods to reduce this phenomenon is essential. in the study, effects of two types of squar and circular collar on a single cylindrical model have been investigated. in the next ...
Scour around non-circular cylinders has seldom been studied before. This paper aims to numerically investigate the flow behaviour and evolution of local scour two single square-shaped piers with 90 ° (square pier) 45 (diamond orientation angles under steady-current live-bed conditions. For this purpose, a coupled approach between hydrodynamic morphodynamic model is developed validated against e...
