Treatment of Anchorage of Main Bars in Reinforced Concrete by Codes of Practice -A Critical Review (Part One: Straight Bar Anchorages)
Keywords:
straight anchorage, bond stress, anchorage length, concrete strength, concrete cover, transverse reinforcement, transverse pressureAbstract
This paper compares important provisions and parameters related to anchorage of straight bars in reinforced concrete of BS8110, EC2 and ACI-318 as well as empirical equations by by Orangun et al , Darwin et al. and Batayneh are also considered in a parametric study.
The study investigates the parameters which have influences on the bond and anchorage as there are some of them have not been considered by all of them and found their significance in obtaining more accurate bond resistance like transverse pressure, transverse reinforcement, the yield strength of the transverse reinforcement, bar geometry, anchorage length, concrete cover and transverse pressure.
A parametric study and test results from literature are used in demonstrating the treatments by them and significant commentaries are given.
