Behaviour of GFRP-strengthened RC cantilever slabs

Review of Anchorage Systems for Externally Bonded FRP Laminates

“…U-Anchors for Type II applications have been studied by Khalifa et al (1999), Micelli et al (2002), Ceroni et al (2008), Beigay et al (2010), and Petty et al (2011). While U-Anchors can potentially be used in Type III applications, such as in studies by Teng et al (2001) and Beigay et al (2010), they are generally not strong enough to resist the large anchoring forces typically required in full-scale applications due to the limited bonded length of FRP within the groove as well as the need to transfer load relatively deeply into the supporting member. Careful consideration should be taken in selecting the U-Anchor arrangement, depth, and location because constructing the required groove may result in stress concentrations in the substrate or a weakened section at the groove location.…”

Cliff roads: An ecological conservation technique for road construction in mountainous regions of China

“…To reduce ecosystem damage in cliff areas, an ancient Chinese cliff path technique has recently been resurrected. The same technique that is used for canopies and balconies (Teng et al, 2001), namely cantilevering, has been used to construct slab roads on the sides of cliffs. At some sites, the slab road is combined with bridge support structures where additional support is needed.…”

Performance of externally bonded GFRP sheets on concrete in tropical environments. Part I: Structural scale tests

“…Degradation of steel reinforcements due to corrosion, cracking of concrete due to weathering, rapidly changing traffic needs (both in terms of intensity and load levels) and recent earthquake damages have necessitated the use of strengthening of basic structural components such as slabs, panels, walls, beams and columns [6]. Tests carried on concrete beams reinforced externally with FRP plates indicate substantial increase in the strength of the beams and decks [7][8][9][10][11][12][13]. Wrapping of columns with FRP have been studied for enhanced performance and are found suitable for seismic column retrofitting [14][15][16].…”
