Experimental and analytical investigations on the effect of steel fibers on the crack behavior and strength of dapped‐end connections

Structural Concrete, EarlyView.
Abstract Reinforced concrete (RC) dapped‐end connections feature a sharp re‐entrant corner subjected to high stress concentrations, leading to wide cracks under service loads and potential durability issues such as reinforcement corrosion. Effective crack control is therefore essential in the design of new dapped‐end connections. Steel fiber reinforced

Anchorage performance of different punching shear reinforcement elements in cracked concrete

Structural Concrete, EarlyView.
Abstract Extensive research has been conducted on the bond and anchorage behavior of reinforcement elements in concrete. While many experimental studies have focused on uncracked concrete, the anchorage performance in the presence of cracks remains insufficiently understood.

Optimizing the embodied carbon of the product stage of reinforced concrete columns

Structural Concrete, EarlyView.
Abstract The construction sector faces urgent sustainability challenges. This study quantifies the potential for reducing embodied carbon in reinforced concrete columns by optimizing concrete strength and reinforcement ratios. The interplay between concrete compressive strength (20–90 MPa), reinforcement percentages (0.2%–2.0%), and embodied carbon ...

Experimental and numerical investigation on the flexural response of GFRP‐reinforced SFRC beams

Structural Concrete, EarlyView.
Abstract In order to address the challenges related to the deformability and ductility of concrete beams reinforced with fiber reinforced polymer (FRP) bars, an alternative solution involving steel fiber reinforced concrete (SFRC) has been proposed. In the present study, a total of seven beams—including one steel‐reinforced reference beam and six glass

Three‐parameter kinematic theory for shear assessment of reinforced concrete short columns

Structural Concrete, EarlyView.
Abstract This work presents a rational kinematics‐based model for assessing the shear capacity of rectangular reinforced concrete short columns. Due to their high stiffness and brittleness, short columns are particularly vulnerable to seismic forces, often exhibiting critical failures.

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 ...

Influence of shear reinforcement detailing on the shear capacity of reinforced concrete beams

Structural Concrete, EarlyView.
Abstract Alternative shear reinforcement layouts that do not fully enclose the longitudinal tensile reinforcement can significantly improve the constructability of reinforced concrete (RC) members. However, their influence on shear transfer mechanisms is not yet fully understood. To address this gap, an experimental program comprising 10 shear tests on

Fracture‐mechanical numerical simulation of punching in reinforced concrete foundations considering soil‐structure interaction and design code evaluation

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 ...
