Abstract
This paper is focused on the design of concrete structures reinforced with modern composite material – Fibre Reinforced Polymer (FRP) reinforcement. It presents actual results from the testing of FRP rods under a simultaneous tensile and shear loading. The results were experimentally obtained on specimens of Glass Fibre Reinforced Polymer (GFRP) reinforcement. The text also points out that the widely used fib Bulletin no. 40 technical report does not provide sufficiently reliable formulas and may overestimate the load-bearing capacity of the element. Therefore, the conclusions formulated are primarily concerned with their practical use in the design of this modern material.
