Feasibility Study of Using Engineered Cementitious Composite and High-Strength Bars in Rigid Bridge Piers Based on Seismic Vulnerability Analysis

Shock and Vibration, 2020
The main function of pier is to transmit the load from superstructure to foundation reliably. Under earthquake action, the main failure reason of bridge is the damage of bridge pier.

Large Deformation Pile‐soil Interaction Under Lateral Vehicle Impact Using Hybrid SPH+FEM and EFG+FEM Models

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT This study presents large deformation computational methods to simulate lateral vehicular impacts on steel piles in granular soil. Soil‐mounted longitudinal barrier systems rely on energy dissipation in both the piles and the surrounding soil to safely redirect errant vehicles, so dynamic pile‐soil interaction is important for design ...

Blue‐Prints for Ocean Governance: Analyzing Resource Sustainability in International Blue Economic Frameworks

Sustainable Development, EarlyView.
ABSTRACT Championed as a pathway for sustainable growth, the “blue economy” (BE) has garnered increasing interest in recent decades. International organizations like the World Bank and the Organization for Economic Cooperation and Development (OECD) increasingly point to marine resources and activities as a “new frontier” for economic growth ...

Damage Assessment of an RC Pier under Noncontact Blast Loading Based on P-I Curves

Shock and Vibration, 2018
Since the 9.11 attacks in New York, terrorist attacks, military strikes, and accidental explosions have caused serious damage to various infrastructures around the world. Accidental traffic explosions in bridge engineering have occurred frequently due to

Simulation of Scour at Bridge Supports

Građevinar, 2020
Groups of piers are used on bridges to minimise scour around bridge supports. The prediction of scour around piers due to interaction of vortices around bridge piers is more complex compared to scour prediction around a single pier.

Bridge-Pier Caisson foundations subjected to normal and thrust faulting:physical experiments versus numerical analysis [PDF]

, 2015
Surface fault ruptures can inflict serious damage to engineering structures built on or near them. In the earthquakes of Kocaeli, Chi-chi, and Wenchuan a number of bridges were crossed by the emerging normal or thrust faults suffering various degrees of ...
