Shear transfer across a single crack in reinforced concrete: Additional detailed tests

Abstract

This report gives information on additional detailed tests concerning shear transfer across a single reinforced crack in concrete. The bond characteristics of 8mm diameter deformed reinforcing bars have been investigated by means of pull-out tests. The bars were embedded in concrete over a length of 40mm and were tested at three different ages of the concrete. Static and sustained as well as repeated loading conditions were applied. Experiments were also carried out on push-off specimens. The axial steel stresses of the embedded reinforcing bars were measured using strain gauges stuck to the centre of each bar. After these tests the microstructure of the steel was investigated to verify whether or not yielding of the bar had occurred.Design & ConstructionCivil Engineering and Geoscience
