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.

Structural Concrete, EarlyView.Abstract The use of fiber reinforced concrete (FRC) in precast tunnel segments is among the most established and representative applications of this material. Over the past two decades, numerous tunnel linings were constructed with partial or total substitution of conventional steel reinforcement by fibers, this yielding to quantifiable benefits in ...

Structural Concrete, EarlyView.Abstract This study investigates the numerical modeling of internal tendon breaks in prestressed concrete structures and evaluates the key parameters affecting accuracy. A combined approach is followed, involving global sensitivity analysis via the Elementary Effects Method and subsequent model calibration using experimental data from distributed fiber‐

Seismic evaluation of the southbound Stellenberg Interchange Bridge, B5593, in South Africa
Structural Concrete, EarlyView.Abstract This study presents a nonlinear finite element assessment of the seismic vulnerability of Bridge B5593, located in the south‐western region of South Africa. Previous evaluations identified a high likelihood of column failure; however, these were based on linear material models incapable of capturing damage evolution.

Structural Concrete, EarlyView.Abstract In precast concrete structures, optimizing the design of corbels by considering the contributions of secondary reinforcement elements can significantly improve construction economy, especially when corbels are repeated multiple times. This paper proposes a strut‐and‐tie model for reinforced concrete corbels subjected to vertical and/or ...

Kinematics‐based model for shear capacity assessment of unreinforced interior beam–column joints
Structural Concrete, EarlyView.Abstract This study presents a kinematics‐based model for assessing the shear strength of reinforced concrete interior beam–column joints without transverse reinforcement. The proposed framework is built on first principles—kinematics, equilibrium, and constitutive relations—and explicitly models discrete cracks by introducing kinematic parameters such

Structural Concrete, EarlyView.Abstract In this study, the structural behavior of small square steel tube‐reinforced self‐compacting concrete (SSTR‐SCC) columns is investigated under symmetric and asymmetric biaxial eccentric loads. Twelve specimens were cast and tested under biaxial eccentric loads.

Structural Concrete, EarlyView.Abstract Current design provisions for punching shear in foundations, including Eurocode 2 (2023) and fib Model Code 2020, are mechanically based models partly calibrated against experimental data from isolated flat slabs and foundation specimens. The available experimental database for foundations is small and only partly representative of realistic ...
