How to Define the interaction of different types of stirrups (90, 135) with the confining concrete and longitudinal reinforcement in ABAQUS?

10 October 2019 1 6K Report

135 deg stirrup (seismic) hooks perform very well than ordinary 90 deg hooks. Also welded stirrups are totally different in performance than simply overlapped hooks. The question is how to model the interactions for such cases in ABAQUS?

Khaled Megahed

I think that modelling these types of stirrups is hard to perform, especially creating a a mesh for circular stirrups with angle 135 in concrete column. Most analyses done in Abaqus assume embedded constraint for modelling abaqus
