Flexural Reinforced Concrete Elements Residual Stresses of Fibres with Limited Reinforcement Bond

Goaras Andriušis, Algirdas Augonis, Mindaugas Augonis, Šarūnas Kelpša, Tadas Zingaila


This article presents calculation of residual stresses of steel fibre and ordinary reinforcement reinforced concrete elements, with limited bond between reinforcement and concrete. This calculation is based on the relationship of cracked middle section crack width and curvature. This relationship is obtained from experimental results, by testing reinforced concrete elements, without steel fibre. The aim of investigation is to find out the force in ordinary reinforcement as the main member evaluated residual stress in fibre. These calculations there were supported on several assumptions that not significantly evaluated the results. In article are described test methods and materials, given schemes of tests and calculations
