Determination of the bond behaviour between reinforcing bars and autoclaved aerated concrete by the ' push - out ' test
" determination of the bond behaviour between reinforcing bars and autoclaved aerated concrete by the " push - out " test . "
According to the experimental results of the 20 push - out specimens , together with the mathematical analysis of the p - sl curves , three characteristic b
On the other hand , due to the difference of the loading form on eccentric loading column with push - out test and short - column test , the bond - slip performance ca n ' t be displayed in it
In order to determine the relations between the four main bond - anchoring factors - concrete strength , concrete cover thickness , steel shape embedment length and the ratio of the transverse hoops - and the bond strength , and establish the bond - slip constitutive relations , 16 standard push - out test specimens were designed , and 4 comparison specimens were additionally designed to find the difference of the bond performance between the web , inside and outside of flanges the steel shape
