Effective axial strength of laterally strengthened RC pier heads with post‐tensioning method
Structural Concrete, EarlyView.Abstract This study investigates the structural performance enhancement of reinforced concrete (RC) pier heads laterally strengthened with unbonded post‐tensioning (PT) to accommodate increased design loads following a deck replacement of an existing railway bridge.

Torsional Behavior of RC Beams with Opening Using (CFRP - GFRP - Steel) Stirrups
, 2016 This paper presents the torsional behavior of R.C. beams strengthened with externally steel stirrups, steel links and Fiber Reinforced Polymers (FRP) systems, R.C beams with web opening subjected to pure torsion. A total six rectangular beams were tested.

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.

FINITE ELEMENT MODELLING AND ANALYSIS OF CONCRETE CONFINED BY STIRRUPS IN SQUARE RC COLUMNS
, 2016 Concrete confined by stirrups with greater ductility than unconfined concrete has been used widely in reinforced concrete (RC) structures and its behavior is the classic topic. As the computer power is improving, an increasing number of modelling studies

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

Vertical shear interaction model between external FRP transverse plates and internal steel stirrups
, 2006 A convenient and proven technique for increasing the vertical shear capacity of reinforced concrete beams is to externally bond fibre reinforced polymer (FRP) to the sides of the beam with the fibres orientated in the transverse or vertical direction ...
