Crashworthiness design of GFRP bar reinforced concrete bridge pier subjected to truck collision

open access: yesCase Studies in Construction Materials, 2023
This study investigates the failure behavior and post-impact damage of glass fiber reinforced polymer (GFRP) bar reinforced bridge pier under truck collision. The finite element model of a benchmark bridge with its pier reinforced with GFRP bars collided

Research on Seismic Performance and Reinforcement Methods for Self-Centering Rocking Steel Bridge Piers

open access: yesApplied Sciences, 2023
To study the seismic performance of self-centering circular-section rocking steel bridge piers whose functions can be restored after an earthquake, a high-precision finite element (FE) analysis model of such a bridge piers was established. The hysteresis

Transient response of bridge piers under eccentric impact of near-fault earthquake

open access: yesScientific Reports, 2022
To study the influence of near-fault earthquake on pier failure, establish a double-span continuous girder bridge. The seismic response of the bridge is calculated using the transient wave function expansion method and the indirect mode function ...

Smoothed Particle Hydrodynamics Simulation And Evaluation Of Water Flow Pressure On Bridge Piers

open access: yesJournal of Applied Science and Engineering, 2023
In this study, a Smoothed Particle Hydrodynamics (SPH) model for fluid-solid interaction is developed considering the effect of water flow transient impact, water pressure and velocity around a bridge pier.

Centrifuge modeling of rocking-isolated inelastic RC bridge piers [PDF]

open access: yes, 2014
Experimental proof is provided of an unconventional seismic design concept, which is based on deliberately underdesigning shallow foundations to promote intense rocking oscillations and thereby to dramatically improve the seismic resilience of structures.

Seismic Performance of Steel Box Bridge Piers with Earthquake-Resilient Function

open access: yesAdvances in Civil Engineering, 2020
A novel steel box bridge pier with replaceable energy dissipation wall plates at the base was proposed. After moderate earthquakes, the damaged energy dissipation wall plates and constraining steel plates on the two sides could be rapidly replaced, while

Turbulent flow structures and scour hole characteristics around circular bridge piers over non-uniform sand bed channels with downward seepage [PDF]

open access: yes, 2019
Bridges play an important role in the transportation of goods and people across rivers. In civil engineering, one of the most important issues is to protect bridge piers from collapse.

Bridge Failure Prevention: An Overview of Self-Protected Pier as Flow Altering Countermeasures for Scour Protection [PDF]

open access: yesCivil Engineering Infrastructures Journal, 2021
The inherent scour process around the bridge piers needs to be considered and crucial to ensure a sustainable and economical bridge design. The performance of any scour protection/controlling devices around bridge piers is determined on how each device ...

Performance of a Damage Protected Highway Bridge Pier Subjected to Bidirectional Earthquake Attack [PDF]

open access: yes, 2009
Recent earthquakes such as Loma Prieta, Northridge, and Kobe have demonstrated a need for a new design philosophy of bridge piers that avoids damage in order to ensure post-earthquake serviceability and reduce financial loss.

Kinematic Response of Bridge Piers

open access: yesProcedia Engineering, 2016
AbstractThis paper deals with the soil-structure interaction that occurs in deep foundations of bridge piers in seismic areas. In particular, the kinematic response of rigid caisson foundations under the passage of obliquely incident polarized shear waves is highlighted and discussed. A Winkler model with translational and rotational impedances is used
