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.

Structural testing and analytical model of Reinforced Concrete (RC) prisms with 3D‐printed concrete permanent formwork under compressive loading

Structural Concrete, EarlyView.
Abstract The implementation of traditional steel reinforcement in 3D concrete printed structures is a major challenge. Although 3D‐printed structures may be used as formwork, the knowledge about their structural contribution is limited. This research aims to experimentally evaluate the structural performance of reinforced concrete prisms with 3D ...

Experimental and Numerical Investigation on the Behavior and Strengthening of Fire-Damaged Reinforced Concrete Walls Using Self-Compacting Concrete Jacketing

Medžiagotyra
Fire exposure significantly compromises the load-bearing capacity of reinforced concrete (RC) structures, highlighting the critical need for effective post-fire rehabilitation strategies. There remains limited knowledge of the post-fire rehabilitation of

Behavior of exterior beam‐column joint reinforced with shape memory alloy

Structural Concrete, EarlyView.
Abstract Beam‐column joints are critical regions in moment‐resisting frames and are particularly susceptible to severe stress concentrations and reinforcement congestion. Conventional design typically relies on dense transverse reinforcement to improve joint performance, resulting in construction difficulties and reinforcement congestion.

Becoming climate sentinels

American Ethnologist, EarlyView.
Abstract In South Korea, forest scientists refashion themselves as “climate sentinels” as they confront subtle yet disquieting shifts in plant seasonality brought about by climate change. Unlike traditional sentinels, who watch for external threats from a frontier, climate sentinels face ecological anomalies and surprises—such as untimely flowering ...

Experimental and theoretical investigation of reinforced concrete columns strengthened with fiber-reinforced polymer-concrete jacketing under eccentric loading

Results in Engineering
Polymer concrete (PC) exhibits superior performance and durability properties compared to conventional cement-based concrete, making it a promising material for structural strengthening applications. However, its effectiveness as a jacketing material for

The road to hell is paved with good intentions: A review and research agenda on rebound effects and win–win strategies

International Journal of Management Reviews, EarlyView.
Abstract Rebound effects describe how efficiency improvements in energy or resource use can increase demand, thereby partially or fully offsetting expected environmental savings. This dynamic complicates win–win strategies that aim to improve environmental and financial performance.
