title = "Optimised Strut and Tie Models for Reinforced Concrete Structures Subjected to Several Limit States",
abstract = "A structural designer needs to ensure adequate performance in both SLS and ULS. Thus when optimising structures, both limit states should be considered simultaneously. For ULS, effective material optimisation exists within FELA, which applies a convex solver. For SLS, an iterative procedure utilising a tangential stiffness matrix is established to solve this also using a convex solver. As an initial step toward optimising solid RC structures, the method is implemented by finding optimal strut and tie models subjected to simultaneous SLS and ULS requirements. Practical and verifiable models were found for simple structures. Large structures were also solved, resulting in an initial design point for more practical solutions. ",
