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.

Influence of calcination temperature on the durability of metakaolin concrete and limitations of conventional testing methods

Structural Concrete, EarlyView.
Abstract Incorporating metakaolin (MK) as a partial cement replacement offers a viable pathway to reduce carbon emissions while improving concrete performance. However, its durability behavior remains inconsistent, and the applicability of durability test methods to MK‐based concrete is not well established.

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.

Strong ground motion and structural damage in the 2023 Kahramanmaraş earthquakes: A comparative case study of numerical predictions and field observations

Structural Concrete, EarlyView.
Abstract On February 6, 2023, southeastern Türkiye was struck by two catastrophic earthquakes (Mw: 7.7 and Mw: 7.6) along the East Anatolian Fault Zone, causing extensive structural failures and significant loss of life. This study evaluates the seismotectonic characteristics of the sequence, analyzes strong ground motion data against the Turkish ...

Achieving sustainable and durable concrete using high‐volume SiO2: Engineering properties, environmental and economic benefits

Structural Concrete, EarlyView.
Abstract This study explores the potential of high‐volume amorphous silica (SiO2) replacement for ordinary Portland cement (OPC) in concrete to reduce carbon emissions. Amorphous SiO2, such as silica fume (SF) and CO2 mineralization‐produced Si‐rich gel, offers superior properties to concrete but is under‐researched for its use in concrete with high ...
