Multi‐level fatigue reliability assessment of reinforced concrete railway bridges

Structural Concrete, EarlyView.
Abstract This paper presents a multi‐level reliability framework for assessing the fatigue life of reinforced concrete (RC) railway trough bridges subjected to cyclic loading. The framework incorporates increasing levels of analytical complexity and real‐world data in four steps. First, an analytical model applies S–N curves and the Palmgren–Miner rule

Enhancing Seismic Resilience: Evaluating Buildings with Passive Energy Dissipation Strategies

Eng
Structures are recommended to be designed and constructed with the integration of structural health monitoring techniques to ensure that they can dissipate a large amount of energy without considerable damage when subjected to earthquakes. Hysteretic (H),

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

Structural 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.

Proposal for vertical distribution of seismic design load and equivalent isolation ratio for seismically isolated buildings with multiple types of dampers: Vertical distribution of seismic design load for seismically isolated buildings corresponding to diversity of seismic isolation devices, part 2

Japan Architectural Review
As previously reported, we have proposed a vertical distribution of seismic design load for seismically isolated buildings (SIBs) corresponding to diversity of seismic isolation devices such as hysteretic dampers and velocity‐dependent dampers.

Evaluation of the Response of Posttensioned Steel Frames with Energy Dissipators Using Equivalent Single-Degree-of-Freedom Systems

Advances in Materials Science and Engineering, 2014
The hysteretic energy (EH) dissipated in posttensioned steel frames (PTSF) with hysteretic dampers is calculated by using equivalent single-degree-of-freedom systems (ESDOFS), where the nonlinearity of both the steel bars (beam and columns) and the ...

Development and application of metallic dampers in bridge engineering: A review

Journal of Traffic and Transportation Engineering (English ed. Online)
Bridges may suffer from large-amplitude vibrations due to strong winds, earthquakes, human-induced loads, and vehicle-induced dynamic loads. Metallic dampers employed the energy dissipation from the hysteretic behavior of metal materials are among the ...

Shaking Table Tests and Numerical Analysis of Rocking Vault‐Shaped Segmental Piers Equipped With an Annular Double Sliding System

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 10, Page 2233-2254, August 2026.
ABSTRACT To enhance the structural robustness of bridges, a rocking arch‐shaped segmental pier with a double sliding system was previously proposed as a low‐cost solution to protect bridges in developing countries. The rocking behavior is triggered by halting the sliding motion, which increases the horizontal load‐bearing capacity and limits ...
