Abstract The study of scouring around bridge piers is very significant and plays a important role in the safe economical design piers. term process by which bed particles periphery pier get eroded removed over certain depth resulting formation scour hole This paper presents detailed investigation local six different shapes namely rectangular, circular, chamfered, joukowsky, oblong, sharp-nosed ...

Abstract To meet the high durable requirements of assembled bridge piers in marine environment, a new grout is used sleeve to improve corrosion resistance pier bottom. The seismic performance adopting this studied. Firstly, dynamic analysis model reinforced concrete with established using finite element software ABAQUS. Moreover, damage modes, hysteresis curves, and energy consumption for low r...

For the lifetime assessment of running safety a train in aggressive environments and earthquake-prone areas, effects corrosion on seismic performance must be considered. Research trains, including damage, is limited, despite fact that trains high-speed railway bridges has been extensively examined. In this work, was evaluated using time-varying corroded bridge finite-element model established O...

The aim of this work is to estimate the seismic reliability a simple typical two-span lifeline base-isolated bridge designed behave essentially elastic or as per Canadian Highway Bridge Design Code, for seven localities in Quebec. Two limit states are considered possible failure due unacceptable damage: flexure at pier-base and displacement within isolation systems (SIS). main problem random va...

The study aims to further standardize the construction process, improve quality, and ensure stability of infrastructure construction. continuous rigid-frame bridge is taken as research object, finite element model body established by using beam element, overall analyzed in completion stages. Moreover, coefficient buckling mode are under different working conditions each stage, linear variation ...

Bridge piers which are constructed in the track of high water rivers cause some variations in the flow patterns. This variation mostly is a result of the changes in river sections. Decreasing the river section, bridge piers significantly impress the flow patterns. Once the flow approaches the piers, the stream lines change their order, causing the appearance of different flow patterns around th...

An experimental study has been conducted on the effectiveness of two types of flow-altering countermeasures placed around a cylindrical pier under clear water condition, which include sacrificial piles and submerged vanes. Their arrangements follow the optimal configurations recommended in the published articles with some modification. The temporal evolution of maximum scour depth and its equil...

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...
