Locating co-seismic deformation using multi-GNSS ionospheric sounding

Les grands séismes de subduction, situés dans des zones d'interface Terre-Mer, génèrent les tsunamis les plus destructeurs. Dans les zones faiblement dotées d'équipements de protection comme par exemple au Japon, la sécurité des populations repose entièrement sur des mesures de prévention et sur des systèmes d'alerte aux tsunamis efficaces, alimentés ...

The challenges of GFRP RC beam design for limit states

Structural Concrete, EarlyView.
Abstract Glass fiber reinforced polymer (GFRP) bars are used ever more frequently in concrete construction due to their non‐corrosive and anti‐magnetic properties. Their research over the past decades focused on fundamental questions, such as the design aspects of beams under flexural loads.

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.

Three‐parameter kinematic theory for shear assessment of reinforced concrete short columns

Structural Concrete, EarlyView.
Abstract This work presents a rational kinematics‐based model for assessing the shear capacity of rectangular reinforced concrete short columns. Due to their high stiffness and brittleness, short columns are particularly vulnerable to seismic forces, often exhibiting critical failures.

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.

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.
