Dominant efficacy of the new developed ‘‘externally bonded reinforcement on grooves” (EBROG) technique in comparison with ‘‘externally bonded reinforcement” (EBR) method has been previously shown when fiber reinforced polymer (FRP) composites are used for st ...
The main purpose of the current study is to investigate bond behavior of fiber reinforced polymer (FRP)-to-concrete under mixed-mode I/II loading. To attain this end, 150 × 150 × 330 mm concrete prisms were cast and strengthened by carbon fiber reinforced ...
In the current study, the glass transition and tensile behavior of three different cold-curing two-component epoxies, commercially available as structural adhesives for carbon fiber reinforced polymer (CFRP) strengthening of concrete and steel structures, ...
The bond behavior of carbon fiber–reinforced polymer (CFRP) sheets attached to concrete surface subject to mixed-mode I/II loading through single lap-shear tests is assessed. A 63 concrete prism specimens of 150 × 150 × 330 mm were prepared through externa ...
A large number of design approaches for structural concrete rely on the applicability of limit analysis. This is for instance the case of bending and shear design in members with transverse reinforcement, where it is assumed that plastic compression fields ...
Offshore lighthouses are a remarkable historical heritage often over 100 years old. The management of their aging is a challenge. The extremely low permeability of Ultra-High- Performance Fiber Reinforced Concretes (UHPFRC), combined with their outstanding ...
An evaluation of cement- and resin-based grout materials for applications in carbon fiber-reinforced polymer (CFRP) ground anchor heads composed of high-strength grout and a CFRP strap was conducted. Uniaxial compression experiments were performed on cylin ...
Carbon fiber reinforced polymer (CFRP) composites have exhibited a great potential for strengthening of steel structures. In the current study, an innovative prestressed unbonded reinforcement (PUR) system is introduced for fatigue strengthening of existin ...
FRP (fiber reinforced polymer) strips are used to flexurally strengthen reinforced concrete (RC) beams. The global bond strength namely the maximum transferable bond stress due to the increase of FRP tensile stress in a cracked concrete element (subsequent ...
Permanent post-tensioned ground anchors are widely used for the stabilization of different structures in civil engineering. Carbon fiber-reinforced polymer (CFRP) tendons have been proposed to replace steel tendons in ground anchors to solve the durability ...
