Application of strut-and-tie model on eccentric columns

Abstract

The popular strut-and-tie model is currently de fined by EC2 as a standard tool for simple structures. This paper explores the possibility of application of the strut and-tie model on more complex structures, specifically on the eccentric columns. Comparison with full numerical simulation shows that the strut-and-tie model can correctly predict the maximum bearing capacity. The optimization of structure cost associated with the optimization of the strut-and-tie model topology is demonstrated to remain simple even for the complex case of eccentric columns. The practical optimum design of reinforcement using the strut-and-tie model is also presented.
