FRP lacks ductility so its application as reinforcement of new structures in seismic areas is not common. Seismic actions can produce a large capacity and ductility demand. Although large capacity is readily available in FRP reinforced concrete elements, ductility capacity is often lacking. A large amount of building stock consists of low to mid-rise buildings with a significant number of walls. In such structures, most of the capacity is usually provided by walls. This means that the behaviour of the whole structure depends on the behaviour of the walls, more specifically on their load bearing and lateral drift capacity. For squat walls, there is usually an excess of load bearing capacity but for more slender walls, some amount of ductility is required. This ductility is provided by bending of an element, so drift capacity depends on curvature capacity. In this paper, curvature ductility of FRPRC walls with different reinforcement configurations is theoretically and numerically analysed.
There is a large number of different FRP rebar products available on the market, each with different strength and ultimate strain. Using only one type of rebar in a wall can provide some amount of ductility, depending on the diameter and spacing of bars. However, combining different products can lead to a significant change in the overall behaviour of an element. This paper provides a quick, preliminary analysis of FRPRC slender walls to provide a basis for developing more comprehensive research and guide future experimental efforts.
