Experimental study of the size effect on punching shear of steel fiber reinforced concrete slabs

Structural Concrete, EarlyView.
Abstract As the behavior and design of steel fiber reinforced concrete slabs subjected to punching still remain an area of concern, the present work aims to provide a further contribution to the knowledge on punching behavior of slabs without transverse reinforcement.

Experimental and theoretical investigation of longitudinal tunnel lining joints with confining reinforcement

Structural Concrete, EarlyView.
Abstract Precast reinforced concrete segmental linings are frequently used in modern tunneling. In these linings, the longitudinal joints typically have a reduced contact cross‐section and thus often govern the design, particularly in tunnels under high hydrostatic pressure or crossing squeezing or swelling ground with correspondingly high ...

Performance of pre-cracked RC beams shear strengthened with NSM CFRP laminates [PDF]

, 2012
The strengthening of an existing Reinforced Concrete (RC) structure often involves concrete in a cracked state. To evaluate the effect of existing cracks on the behavior of RC beams shear strengthened according to the Near Surface Mounted (NSM) technique

Strengthening of Existing Reinforced Concrete (RC) Columns using Ultra High Performance Fiber Reinforced Concrete (UHPFRC) Jackets

The strengthening of existing columns using additional Reinforced Concrete (RC) jackets is one of the most popular techniques for the enhancement of column’s stiffness, load bearing capacity and ductility. Important parameters affecting the effectiveness of this method are the strength of the additional concrete, the concrete shrinkage and the ...

An enhanced analytical model for predicting shear strength in reinforced concrete beams with corroded reinforcement

Structural Concrete, EarlyView.
Abstract This paper presents an analytical model to predict the shear strength of RC beams affected by corrosion within the Level IIb framework of fib Model Code 2020. Corrosion is accounted for by (i) reducing the area of longitudinal reinforcement, (ii) degrading the yield strength of stirrups according to Imperatore's law, and (iii) reducing the ...

Flexural performance of basalt FRP reinforced concrete beams with and without discrete basalt fibers

Discover Civil Engineering
Steel corrosion in reinforced concrete has driven the search for alternative materials. This study investigates the flexural behavior of Basalt Fiber Reinforced Polymer (BFRP) reinforced concrete (RC) beams, including the effect of basalt fibers on crack

Experimental investigation on post‐installed anchorages with cast‐in anchor reinforcement under tension loading

Structural Concrete, EarlyView.
Abstract Anchors are used to connect different structural and non‐structural components to reinforced concrete structures. Anchorages when subjected to tension loading might fail in different failure modes, with concrete cone breakout (CCB) being one of the most common.

Evaluations of the effectiveness of the near‐surface mounted steel materials in strengthening short RC wall‐like columns with openings

Structural Concrete, EarlyView.
Abstract In practice, reinforced concrete (RC) wall‐like columns often have openings to facilitate building services, which creates stress concentrations around the opening, resulting in the weakening of their load‐carrying capacity. This study proposes innovative strengthening methods using near‐surface mounted (NSM) incorporating steel materials to ...

Assessment of the effectiveness of the NSM shear strengthening technique for deep T cross section RC beams [PDF]

, 2013
The effectiveness of the near surface mounted (NSM) technique with carbon fibre reinforced polymer (CFRP) laminates for the shear strengthening of reinforced concrete (RC) beams has been demonstrated during the last decade.

Performance enhancement of reinforced concrete columns using stainless steel and galvanized steel plates: Experimental and numerical investigation

Structural Concrete, EarlyView.
Abstract This study introduces an innovative approach to strengthening defected reinforced concrete (RC) columns using externally bonded stainless steel and galvanized steel plates. Unlike conventional strengthening methods, this technique replaces traditional transverse stirrups with steel sheets, providing enhanced confinement and ductility.
