Simulation of debris flow impacting bridge pier tests based on smooth particle hydromechanics method

open access: yesRock and Soil Mechanics, 2021
In this paper, a three-dimensional numerical simulation model is established based on smooth particle hydrodynamics (SPH) method. In this model, the dynamic behavior of debris flow is described by using the Bingham fluid model, and the bridge pier is ...

Large‐scale tests of 50‐year‐old prestressed concrete bridge girders

open access: yesStructural Concrete, EarlyView.
Abstract An experimental investigation has been carried out as part of the BRIDGE|50 research project, focusing on large‐scale loading tests performed on five 50‐year‐old prestressed concrete (PC) girders. The study aimed at evaluating the structural response of five girders retrieved from a viaduct in the urban area of Turin, Italy, subjected to 4 ...

Local scour at group of bridge piers founded in gravel bed in staggered arrangement

open access: yesResults in Engineering
Local scour around bridge piers is the common cause of undermining of bridge foundation. Many researchers have studied local scour around bridge pier in finer sediment bed.

Seismic evaluation of the southbound Stellenberg Interchange Bridge, B5593, in South Africa

open access: yesStructural Concrete, EarlyView.
Abstract This study presents a nonlinear finite element assessment of the seismic vulnerability of Bridge B5593, located in the south‐western region of South Africa. Previous evaluations identified a high likelihood of column failure; however, these were based on linear material models incapable of capturing damage evolution.

Dynamic analysis of debris flow impact on double-column bridge piers based on SPH-FEM coupling

open access: yesShenzhen Daxue xuebao. Ligong ban
Based on the smoothed particle hydrodynamics-finite element method (SPH-FEM), a dynamic interaction model of debris flow, comprising both slurry and boulders as well as impacting a double-column bridge pier, is constructed to study the dynamic response ...

Behavior of manufactured sand and recycled coarse aggregate concrete‐filled steel tubular stub columns with circular section

open access: yesStructural Concrete, EarlyView.
Abstract Accelerated urbanization has intensified environmental concerns due to excessive natural resource consumption and construction waste generation. Circular concrete‐filled steel tube (CFST) columns incorporating manufactured sand recycled coarse aggregate (MS‐RCA) concrete have emerged as an innovative composite element offering notable ...

Morphodynamic changes around a bridge pier [PDF]

open access: yes, 2018
River structures, like bridge piers and groynes, obstruct the flow thereby modifying the flow field around them and causing development of localized scour. Field observations and laboratory experiments suggest that local scour holes may affect

Effective axial strength of laterally strengthened RC pier heads with post‐tensioning method

open access: yesStructural Concrete, EarlyView.
Abstract This study investigates the structural performance enhancement of reinforced concrete (RC) pier heads laterally strengthened with unbonded post‐tensioning (PT) to accommodate increased design loads following a deck replacement of an existing railway bridge.
