DETERMINATION OF MODAL PARAMETERS OF REINFORCED CONCRETE TUNNEL RETROFITTED WITH CFRP USING FINITE ELEMENT METHOD
Main Article Content
Abstract
In this paper, the effectiveness of (CFRP) fabric-reinforced concrete, as a means of increasing the rigidity of tunnel lining, was experimentally and analytically investigated. Carbon fiber reinforced polymer (CFRP) is a practical option construction material that has been utilized considerably in the reinforcement of concrete structures. Reinforcement has been implemented by wrapping 4 mm thick CFRP fabric around a concrete tunnel of 5 m in diameter and 25 m in length. The differences between modal parameters of the concrete tunnel and CFRP reinforced concrete tunnel were compared. These modal parameters are period and mode shapes. The first 5 modes of the situation with and without (CFRP) were examined with finite element method. Improvements between 7.86% - 30.24% have been observed in the periods of the first 5 modes. Accordingly, CFRP reinforcement method can be used for safety on concrete tunnels.
