Sensitivity study on accuracy and relevant parameters in numerical modeling of internal tendon breaks

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‐

Mechanical, rheological, and durability performances of GGBS‐based concrete for potential application to prestressed structures

Structural Concrete, EarlyView.
Abstract Ground granulated blast‐furnace slag (GGBS) is a widely used clinker substitute in concrete, recognized for its potential to significantly reduce environmental impacts. However, its application in prestressed concrete remains limited in several countries, mainly due to concerns regarding early‐age mechanical performance and long‐term ...

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.

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
