Relaxation of Glass Based Composite Reinforcement Subjected to Pre-stressing of Concrete Members
Original language description
A significant demand for new materials is today especially for materials that can withstand more than usual and bring better properties within. Answer can be found in composite materials when dealing with reinforcement in concrete. Carbon lamellas externally glued to the structural elements are well known. Application of prestressed composite rod as internal reinforcement brings many new questions. Regarding losses in pre-stressing tendon relaxation is one we focus on in this paper. Main objective of this paper is therefore presentation of GFRP rod relaxation which has been tested in Experimental Centre of CTU in Prague. Furthermore a numerical model of relaxation has been created hand in hand with experiment outcome. This paper shows results of test which has run for 132 days.
