Abstract

The pullout experiments of 9 HRB500 bond-anchorage specimens are carried out. The influence of the quantity of bundled bars, anchorage length on the bond-anchorage behavior of HRB500 bundled bars is comparatively analysed. The load slip curve of bundled bar is obtained, and the bond-anchoring mechanism between steel bar and concrete is analysed. Studies show that there are two failure patterns of HRB500 bundled bar which are pull-out failure and splitting failure. Average bond-anchoring strength decrease with increasing of number of steel bars and anchorage length.
