Effective axial strength of laterally strengthened RC pier heads with post‐tensioning method

Structural Concrete, EarlyView.
Abstract This study investigates the structural performance enhancement of reinforced concrete (RC) pier heads laterally strengthened with unbonded post‐tensioning (PT) to accommodate increased design loads following a deck replacement of an existing railway bridge.

Insights from mining-induced seismic occurrence and migration signals based on surface subsidence and overburden movement

International Journal of Coal Science & Technology
In recent years, there has been an increasing incidence of overburden movements, resulting in surface subsidence, triggered by deep coal mining operations.

Deflection‐based assessment of residual prestress in simply‐supported bridges accounting for creep variability

Structural Concrete, EarlyView.
Abstract Several test methods have been proposed in the literature for measuring the level of residual prestress, most of them involving either semi‐ or fully destructive techniques for local measurements which could be highly sensitive to boundary conditions and execution details.

Towards controlling induced seismicity

, 2020
Induced seismicity has become widespread as a result of fluid injection in the subsurface for energy related activities, such as geothermal energy, geologic carbon storage and subsurface energy storage.

Contribution of dowel action to interfacial shear transfer in flat joints with unbonded posttensioned bars for precast segmental bridges

Structural Concrete, EarlyView.
Abstract Dry joints are widely used in precast segmental bridge construction because they simplify assembly and accelerate erection. Incorporating fasteners crossing flat dry joints represents an innovative configuration for this type of connection.

Eco‐ductile design of RC columns: Resolving the conflict between embodied carbon and curvature ductility

Structural Concrete, EarlyView.
Abstract Reducing embodied carbon emissions in structural design is of critical importance in combating global climate change. However, the increased material usage and heavy confinement reinforcement required to meet high ductility demands in reinforced concrete columns directly conflict with environmental sustainability goals.
