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.

Testing and modeling reinforced 3D concrete printing
Structural Concrete, EarlyView.Abstract 3D Concrete Printing (3DCP) provides several advantages, including construction productivity and sustainability, although the presence of cold joints reduces structural performance, particularly in zones subjected to tensile stresses. In addition, it is difficult to reinforce 3DCP structures with conventional steel rebars, generally used to ...

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

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.

Structural Concrete, EarlyView.Abstract This paper presents a regression‐based methodology to estimate the Torsional Stiffness Reduction Factor (TSRF) of reinforced concrete beams under combined torsion and shear. A numerical database of 6816 samples was generated using the Combined Action Softened Truss Model (CA‐STM) implemented in Python, considering design guidelines prescribed ...

Evaluating structural resistance and updating modeling uncertainties through testing
Structural Concrete, EarlyView.Abstract The aging of infrastructure necessitates a robust and rational methodology for the assessment of existing structures. Design codes provide general models which cover different design scenarios and are thus overly conservative. Also, such design approaches lack field data and, if applied directly to existing works, often lead to unnecessarily ...
