CFRP is an alternative technique for cracking control of high-chloride reinforced concrete (RC) beams. This research, therefore, investigates the strength performance and failure mode behaviour RC beams incorporated with sea sand bonded externally carbon fibre polymer (CFRP) plate. Sea used as a 100% replacement fine aggregate. Three batches were carried out in this including beam (no neither C...

The technique of strengthening steel structures with Carbon Fibre Reinforced Polymer (CFRP) has attracted growing attention in research field and in practice and its environmental durability is of high importance. This paper describes an investigation on the bond characteristics between high modulus CFRP sheet and steel plates under elevated temperature exposures. Tensile tests were carried out...

Design/methodology/approach – Two tests were performed, one on Acoustic Emission artificial signals generated on a CFRP plate and one on an Acousto Ultrasonic setup used for actively detecting impact damage. The waveforms were represented using a data reduction technique based on the Daubechies wavelet and an image processing technique using Chebyshev moments approximation, to get 32 descriptor...

Carbon fiber reinforced polymer (CFRP) is widely used in the lightweight design of high-speed trains due to its high specific strength. In order further reduce weight train body, it necessary study joining process and fatigue properties CFRP/aluminum alloys (CFRP/Al) structure. this work, CFRP plate 5083P-O aluminum were successfully connected by an induction brazing method. The optimum paramet...

Abstract The interfacial stress in a carbon fiber-reinforced polymer (CFRP) plate for strengthening the top flange of box-girder bridge was theoretically investigated. According to force analysis results structure, most unfavorable area selected modeling analysis. Using simplified beam model, CFRP plate-concrete interfacial-stress calculation model derived, and closed-form solution obtained. Eq...

This paper describes a research program that was conducted in two phases to study the behavior of a high modulus CFRP system for strengthening steel structures. The first phase of the research consisted of an experimental program and finite element analysis to study the bond characteristics of the system. The findings indicate that a reverse tapered plate end detail can effectively increase the...

This paper investigates the fatigue behaviour of out-of-plane gusset welded joints strengthened with carbon fibre reinforced polymer (CFRP) laminates. Two notches were introduced at the weld toes adjacent to longitudinal plate ends to simulate the initial damage. Variables including the stress range, singleor double-sided strengthening and modulus of CFRP materials were considered. It was found...

─This paper presents the retrofitting of beam-column joint using CFRP (Carbon Fiber Reinforced Polymer) and steel plate. This specimen was tested until failure up to 1.0% drift. This joint suffered severe damages and diagonal cracks at upper crack at upper column before retrofitted. CFRP were wrapped at corbel, bottom and top of the column. Steel plates with bonding were attached to the two bea...
