Large‐scale tests of 50‐year‐old prestressed concrete bridge girders
Structural Concrete, EarlyView.Abstract An experimental investigation has been carried out as part of the BRIDGE|50 research project, focusing on large‐scale loading tests performed on five 50‐year‐old prestressed concrete (PC) girders. The study aimed at evaluating the structural response of five girders retrieved from a viaduct in the urban area of Turin, Italy, subjected to 4 ...

Flexural performance of concrete‐filled steel tubular beams with wood chip aggregate
Structural Concrete, EarlyView.Abstract This study investigates the flexural performance of concrete‐filled steel tubular (CFST) beams with partial replacement of aggregates by wood chips (0%–25%) through experimental and numerical analysis. This study is novel in that it experimentally and numerically investigates the flexural behavior of CFST beams with partial replacement of ...

Structural Concrete, EarlyView.Abstract Compression field approaches such as the Cracked Membrane Model with fixed, interlocked cracks (CMM‐F) are efficient tools for the mechanical modeling of reinforced concrete elements, providing the mechanical model σ=fε$$ \boldsymbol{\upsigma} =f\left(\boldsymbol{\upvarepsilon} \right) $$ required for finite element analyses.
