Fire behaviour of FRP-strengthened reinforced concrete structural elements: A state-of-the-art review

“…8); it was not possible to identify when the CFRP system lost effectiveness. Adelzadeh et al [47] extended this study with tests on two additional T-beams following a similar test procedure. The beams were CFRP-strengthened in flexure and insulated with 40 mm of cement-based, spray-applied mortar on their lateral and bottom faces.…”

“…Depending on the protection system applied, the time to exceed T g varied between 42 and 104 min. More recently, Adelzadeh et al [47] conducted a similar campaign in which unloaded FRP-strengthened slabs were insulated with a cement-based mortar (40 and 60 mm thick); the adhesive T g was exceeded in approximately 30 min in this case.…”

Numerical Study of FRP Reinforced Concrete Slabs at Elevated Temperature

“…The heat transfer model formerly developed [17] is a finite-volume code, which is capable of predicting temperature in an insulated concrete section. The partial differential equation of heat conduction can be expressed as:…”

Editorial

“…The next paper by Kodur and Dwaikat (2012) offers a useful engineering perspective of the highly complex issue of spalling in concrete subjected to high thermal gradients (especially relevant to high-strength concrete). The fourth paper by Adelzadeh et al (2012) presents a set of tests and numerical modelling to assess the fire resistance of fibre reinforced polymer (FRP)-strengthened concrete members contributing towards resolving the difficult issue of repair and retrofit using FRP materials, which is often questioned in this context. The next paper by Lou et al (2012) provides useful insights into the change in properties of high-strength steel bolts after having been exposed to fire.…”
