TL;DR: In this article, the results of an experimental study on flexural behaviour of reinforced concrete (RC) beams strengthened with carbon fibre (CF)-reinforced plastic sheets were presented. And the results indicated that the flexural rigidity and strength of the RC beams are increased by reinforcing with the CF sheets.

TL;DR: In this article, the applicability of polyethylene fiber reinforced concrete (PEFRC) for use in blast-resistant reinforced concrete structures was investigated and an equation for estimating damage depth to the PEFRC slab subjected to contact detonation was derived based on the test results.

TL;DR: In this paper, the authors present the results of a study on shear reinforcement of reinforced concrete (RC) beams strengthened with carbon fiber (CF) reinforced plastics sheets, and the results indicate that the ultimate shear strength of the strengthened beam is about 1.3 to 1.8 times higher than that of the virgin beam.

TL;DR: In this paper, double-layered reinforced concrete (RC) slabs composed of precast thin plates, 50 mm thick, were fabricated and utilized for contact detonation tests, under a condition that the amount of explosives and the dimensions of specimen were constant respectively.

TL;DR: In this article, an experimental pullout test and finite element model (FEM) analysis are conducted in order to examine the fracture process and the pull-out capacity of a post-installed adhesive anchor bonded with ultra-high-performance fiber-reinforced concrete (UHPFRC).
