Rehabilitation of notch damaged steel beams using a carbon fiber reinforced hybrid polymeric-matrix composite

Correction factors for stress intensity of CFRP-strengthened wide-flange steel beams with various crack configurations

“…CFRP sheets or laminates may be bonded to the damaged substrate of a steel girder, usually tensile soffit, using an adhesive. The majority of experimental or analytical investigations into the behavior of steel structures strengthened with CFRP are dedicated to CFRP-steel interface, load-carrying capacity, and failure mode [5][6][7][8][9][10]. Scant endeavors have been made on evaluating the effectiveness of CFRP-strengthening for steel members using the concept of stress intensity.…”

Measuring changing strain fields in composites with Distributed Fiber-Optic Sensing using the optical backscatter reflectometer

“…A method well suited for measuring strain fields on a component's surface is Digital Imaging Correlations (DIC) [3], DIC uses stereo cameras that need to be placed at a stable position relative to the component. If sufficient accuracy is to be obtained, DIC tends to be limited to the laboratory.…”

Study on mechanical behaviour of cold-formed steel channel pre cut-curving beam

“…[3,4,5,6]. Three types of section profiles are used to signify a damage configuration in the HRS I-beam [4]. There is one profile of the overall cut on the bottom flange, another profile is the cut section along the bottom flange until 25 % of web section and last profile is the cut section along the bottom flange until 50 % of the web section [4].…”

“…There a lot of researchers study about the steel notch such as Refs. [3,4,5,6]. Three types of section profiles are used to signify a damage configuration in the HRS I-beam [4].…”
