Designing for tapers and defects in FRP-strengthened metallic structures [PDF]

, 2005
Adhesively bonded FRP strengthening for metallic structures relies critically on the adhesive joint between the FRP and the metal. Current best-practice in design allows the distribution of shear and peel stress along the adhesive connection to be ...

Synthesis and characterization of polymer networks obtained by conventional radical and RAFT copolymerization processes in supercritical carbon dioxide

The Canadian Journal of Chemical Engineering, EarlyView.
Conventional and RAFT dispersion copolymerizations of HEMA and EGDMA in supercritical CO2 are compared in terms of swelling index (crosslink density), morphology, particle size distribution, and modular differential scanning calorimetry. Abstract The syntheses of net‐poly((2‐hydroxyethylene methacrylate)‐co‐(ethylene glycol dimethacrylate ...

Review of Experimental Studies on Application of FRP for Strengthening of Bridge Structures

Advances in Materials Science and Engineering, 2020
In recent years, fiber-reinforced polymer (FRP) composites have been widely used as a new type of high-performance material in concrete structures. FRP composites have the advantages of high strength, light weight, and corrosion resistance.

Old Timber Reinforcement with FRPs [PDF]

Materials, 2019
The tests included the determination of the reinforcement effectiveness of old larch timber originating from a building built in 1860 with the use of carbon-fibre and aramid-fibre mats and strips, BFRPs and GFRPs. The test results showed that in old solid timber pieces from European larch (Larix decidua Mill.), the highest mean flexural bending ...

Artificial Intelligence and Corporate Social Irresponsibility

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study examines whether and how firms' adoption of artificial intelligence (AI) is associated with corporate social irresponsibility (CSI). Ex ante, theories provide conflicting predictions regarding this association, making it an important empirical question.

Model uncertainty of externally bonded FRP-to-concrete joints

, 2017
This paper presents a study of the model factor ε for bond strength model of fiber reinforced polymer (FRP)-to-concrete joints, which is defined as the ratio of tested bond strength to the predicted result by the model.
