Abstract
In this report pull-out tests with various embedding lengths are described. The concrete compressive strength was about 45 N/mm2. The tests were carried out at various interval pressure ratios. Detailed measurement by means of strain gages inside the bars made it possible to discuss the bond behavior of increasing anchorage lengths at different lateral pressures. It was found that an increase in the bond length relative to the shortest test length resulted first of all in an increase in the average bond stress capacity. With a further increase in the bond length these bond stresses decreased again. The bond effect near the loaded end of the bar was smaller than over the remaining bond length in particular in the case of tests with lateral pressure, except in the case of low load levels. In the case of large anchorage lengths two bond stress maxima were noticed. One in the load-adjacent third of the bond length, and one in the middle portion or in the unloaded end portion of the bond length.
