Seismic performance of bridge pier integrated by multiple steel pipes with directly-connected piles using soil-water coupled three-dimensional elasto-plastic finite element analysis

Soils and Foundations
A bridge pier integrated by multiple steel pipes with directly-connected piles was proposed as a way to design a rational foundation for bridge pier structures, and its feasibility was examined by comparing its seismic behaviour with that of a bridge ...

Reliability Analysis of the Main Pier during the Construction Period of HLCR Bridges

Applied Sciences, 2022
In the process of cradle construction for high-pier, long-span, continuous, rigid-frame (HLCR) bridges, the strength failure and instability damage of the main pier will directly affect the bridge construction safety.

Design, Analysis, and Experimental Validation of a Variable‐Gap Magnetorheological Damper for Seat Suspension

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT To address the dual challenges of routine driving vibration and impact loads in vehicle seat suspensions, a novel variable‐gap magnetorheological damper (VGMRD) is proposed. By combining a tapered piston with a conformal variable‐diameter cylinder, stroke‐dependent, dual‐mode damping characteristics are achieved without the need for complex ...

The 2‐D Orthogonal Packing Problem With Multiple Levels of Prioritization: A Spatial Optimization Perspective

Naval Research Logistics (NRL), EarlyView.
ABSTRACT This paper addresses two‐dimensional orthogonal packing within a confined space, integrating bin packing principles with facility layout concepts to address scenarios in which items must not only fit but also be arranged according to spatial priorities.

Physical Modeling of Local Scouring around Bridge Piers in Erodable Bed

, 2007
The construction of bridges in alluvial channels will cause a contraction in the waterway at the bridge site. The contraction in the waterway will cause a significant scour at that site.

Potential of Epoxidised Natural Rubber Alumina Nanoparticles (ENRAN) sheet as local bridge pier scour countermeasure

Ain Shams Engineering Journal, 2021
This study attempts to reduce scour depth due to localised scour around a bridge pier by introducing Epoxidised Natural Rubber Alumina Nanoparticles (ENRAN) sheet acting as bridge pier sheathing.

Fiber‐Reinforced Bio‐Epoxy Composites: Degradation Mechanisms in Saline Environment

Polymer Composites, EarlyView.
Constituent level degradation of bio‐epoxy composites after saline aging. ABSTRACT This study examines the degradation behavior of bio‐epoxy composites reinforced with glass, basalt, carbon, and flax fiber yarns in a simulated saline environment. Fiber yarns and composite samples were exposed to 3.5% NaCl solution at 60°C for up to 3000 h.

Isolation, Insularity and Resilience: A Review of the Geophysical, Socioeconomic, and Environmental Vulnerabilities of Gran Canaria and Lesvos Islands for Policy Interventions to Global Change

Sustainable Development, EarlyView.
ABSTRACT The dynamic nature of small islands being geographically isolated and their perceived connectedness with global networks complicates research attempts to draw general conclusions on whether insularity leads to marginalization or strengthens their resilience for sustainable development.

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

Results 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.

Impacts of bridge-pier types on balancing ice jams: an experimental study

Shui kexue jinzhan, 2018
The presence of ice jam increases the possibility of upstream water level, which can easily trigger ice jam flooding. Bridge pier types can significantly influence backwater heights.
