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.

Concrete with a very high number of load cycles—Identification of stress levels for efficient investigation of fatigue behavior

Structural Concrete, EarlyView.
Abstract Fatigue stresses are receiving increasing attention in structural engineering, particularly in the design of increasingly slender structures. However, the mechanical response of concrete—particularly its fatigue behavior under very high numbers of load cycles—is still scarcely understood.

Flexural behavior of precast prestressed slabs with embedded building service systems

Structural Concrete, EarlyView.
Abstract Dry‐assembled precast concrete construction is rapidly spreading in many parts of the world due to the several advantages offered by industrialized construction. In order to speed up not only the assemblage of the structure, but also the full integrated building process, engineering systems (mechanical–electrical–plumbing) may be prefabricated

Bond, tension‐stiffening, and cracking in multi‐generational recycled aggregate concrete subjected to shrinkage strains

Structural Concrete, EarlyView.
Abstract The concrete industry is responsible for a significant portion of global waste production and multi‐generation recycled aggregate concrete (MGRAC) is a means to allow the sector to transition to a circular economy framework. To predict the behavior of MGRAC at the member level there is a need to understand the underlying mechanics of bond ...

Evaluation of cold joint effects on the microstructure and mechanical behavior of three‐dimensional printed concrete specimen

Structural Concrete, EarlyView.
Abstract 3D concrete printing (3DCP) is an automated construction technique that uses an extrusion process to fabricate structures efficiently. However, the layer‐by‐layer process can create interlayer weaknesses, and interruptions during printing can result in cold joints, which can negatively affect the structural behavior.
