Strengthening the Water Underground Concrete Reservoirs Using the FRP Materials
The goal of current research was to strengthen water underground concrete reservoirs using FRP materials. So, in this research, first of all, structural system, seismic behavior of concrete underground reservoirs, damage to them and their failure mechanism have been shown. Then, hydrodynamics behavior of reservoirs and issues of water and structure interactions have been reviewed. After all, it has been referred to a strengthening method with FRP composite fibers and their application in seismic strength of structures. Finally, these results have been compared with the modelling of underground concrete reservoir using the ABAQUS software and reservoir`s dynamic behavior in normal mode and strength mode have been reviewed (with FRP fibers). Furthermore, suitable approaches have been presented for strengthening this kind of reservoirs. According to obtained results, acceleration maps had the largest damage to reservoir walls, because they had the maximum amount of ground acceleration. So, they must be strengthened with the best solution. Thus, according to the conducted modelling and review of the previous studies and research and considering the strength of performance work, using FRP materials can be one of the main and effective solutions for this ground.
