The effect on load-bearing behavior on the inclination of the rovings in textile-reinforced concrete with respect to the load direction is investigated. An analytical model that takes into account the increased bond capacity due to lateral pressure on the roving at the crack edge is developed. Two important parameters are introduced: the length, along which the roving changes its direction and is subjected to lateral pressure, and a parameter describing the increase in bond performance depending on the lateral pressure. The effect of these parameters is demonstrated by numerical examples.
