Slip of Steel Bars in Concrete Joints Under Cyclic Loading
Publication: Journal of Structural Engineering
Volume 114, Issue 9
Abstract
A closed form solution for predicting the generalized slip response of reinforcing steel bars anchored inside beam‐column joints is presented. It allows computation of bond stresses, steel stresses, and slip distribution along the bar anchorage length under given generalized steel stresses at the boundaries. The solution takes advantage of some theoretical and experimental observations regarding the bond and steel stress characteristics inside a beam‐column joint. The main features of the proposed model is that it depends only on the monotonic ascending portion of the local bond stress‐slip relationship of the reinforcing bar, and it bypasses the definition of its local bond stress‐slip relationship under severe slip reversals. Results predicted by the model are found to be in good agreement with experimental results and finite element predictions.
