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 ...

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.

Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Considering the needs for reducing carbon emissions and except for extreme cases of very degraded existing structures, research on technologies allowing continued use or upgrading of older buildings has become a priority topic. Generally, research on upgrading of reinforced concrete frame structures certainly has a prominent role, because of ...

Time‐Variant Seismic Fragility of Reinforced Concrete Bridge Piers Considering Degradation Phenomena
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Aging and environmental exposure progressively deteriorate the physical and mechanical properties of construction materials, thereby affecting the safety and functionality of existing infrastructure. Corrosion of steel rebars in reinforced concrete structures is widely acknowledged as the most common and detrimental degradation phenomenon, as ...
