Flexural Behavior of Ultra-High Performance Fiber Reinforced Concrete Scale Tunnel Segment

E3S Web of Conferences, 2018
To reduce the weight of precast tunnel segment, ultra-high performance fiber reinforced concrete (UHPFRC) was studied to cast the segment. The flexural performance of UHPFRC scale tunnel segments were tested in this work. The weight of the UHPFRC thinner

Concrete in architecture: Redefining form, space, function, and insights from bibliometric analysis

Structural Concrete, EarlyView.
Abstract Concrete has become a cornerstone in architectural and engineering innovation, as it seamlessly integrates structural performance with artistic expression. Its evolution from ancient opus caementicium to contemporary ultra‐high‐performance concrete illustrates its adaptability to the change in technological, environmental, and design paradigms.

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.

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.

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 ...

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.

UHPFRC for concrete repair

MATEC Web of Conferences, 2018
As part of the St. Lawrence Seaway lock maintenance, the current practice is to perform concrete repairs entirely with reinforced concrete, using either ordinary concrete or high performance concrete (HPC) mixtures.

Show Me Your Circle! A Typology of Circular Economy Disclosure Strategies by Multinationals

Abacus, EarlyView.
The circular economy (CE) is featuring more prominently in emerging regulations, codes of best practice, and corporate policies. Yet, accounting research offers limited insight into how circularity is currently conceptualized and communicated in corporate reports.
