Analytical Framework for System‐Level Fragility Surfaces of Reinforced Concrete Bridges Under Mainshock‐Aftershock Sequences

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Conventional single intensity measure (IM) fragility approaches with simplified component dependency assumptions overlook the progressive damage accumulation and evolving inter‐component correlations that govern system behavior under mainshock‐aftershock (MSAS) loading.

Numerical and Experimental Evaluation of a Simplified Lateral Spring Formulation for Rocking Structures

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Rocking podium isolation systems have gained significant research interest as a method of limiting seismic demands on superstructures and eliminating residual post‐earthquake drifts through self‐centring behaviour. However, while numerous models of varying complexity, including analytical, phenomenological, and physical formulations, have been

Energy‐Based Characterisation of Earthquake Damage in Masonry Infills Through Combined In‐Plane and Out‐of‐Plane Experimental Tests

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT The seismic capacity of structural systems/members is usually defined in terms of deformation thresholds. Although this is effective in many circumstances, disregarding cumulative quantities such as hysteretic energy may be ineffective when low‐cycle fatigue is relevant (e.g., long‐duration ground motions, very soft soils, ground‐motion ...

Climate Driven Water Table Changes and Their Influence on Liquefaction Response of Integral Bridges

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Integral abutment bridges (IABs) eliminate bearings and joints but transfer seismic demand directly into the surrounding soil, making their response highly sensitive to groundwater conditions and soil–structure interaction. This study presents a 60 g centrifuge testing programme on single‐span IABs designed to isolate the influence of water ...

Surrogate‐Based Time‐Continuous Seismic Fragility Assessment of Corrosion‐Deteriorated Reinforced Concrete Bridges Under Climate Change

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Seismic fragility assessment of reinforced concrete (RC) bridges exposed to corrosive environments must reliably capture time‐dependent deterioration impacts. Climate change compounds this challenge through nonstationary temperature and humidity variations that accelerate bridge corrosion.
