Abstract
Influence of various variants of external composite reinforcement on the rigidity of flexible compressed elements
Incoming article date: 20.12.2017Comparison of the results of the deformation and stiffness test of flexible compressed reinforced concrete colums strengthening with various variants of external transverse and longitudinal reinforcement by composite materials is given. The influence of the rigidity of the reinforcement elements on the deformation properties of the test samples with a cross section of 250x125 (h) mm is given for the flexibility λh = e0 / h = 20, which were tested at eccentricities e0 = 0; 2.0 cm (0.16h) and 4.0 cm (0.32h).
