Experimental Study of Flax Fibre Reinforced Polymer (Ffrp) Strengthened Concrete Plate Under Impact Loading

Abstract eng:
Devastating impact, e.g. falling parapet on a canopy, during strong earthquakes can cause severe damage to structures in the surroundings or even fatalities. This has been observed in many major earthquakes, especially in the case of unreinforced masonry structures. To prevent damage resulting from such an impact loading mitigation measures need to be developed. In this study protective concrete components strengthened by flax fibre reinforced polymer (FFRP) are considered since the impact behaviour of this natural fibre reinforced concrete has not been investigated. The impact properties of the wrapped FFRP strengthened concrete plate were studied through a series of drop-weight tests. The corresponding plain concrete specimens were used as references. The parameters, i.e. impact force, deflection and damage pattern were considered to assess the behaviour of FFRP strengthened concrete plate under an impact loading. Impact resistance was investigated by evaluating the energy absorption of the specimen. The results show that the impact resistance of FFRP strengthened concrete is significantly higher than that of plain concrete. Damage pattern of FFRP concrete plate is different from plain concrete. The study also reveals the influence factors that control the energy dissipation of the specimen which will be used for developing future environmentally friendly protective structures in earthquake regions.
