Abstract

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.
