Modelling of Stirrup Confinement Effects in RC Layered Beam Finite Elements Using a 3D Yield Criterion and Transversal Equilibrium Constraints
Peter Berke,Thierry Massart +1 more
TL;DR: In this article, two numerical formulations for layered beam descriptions accounting explicitly for transversal confinement are implemented and assessed in a contribution focusing on the numerical formulations of both frameworks, and on their assessment against experimental results available in the literature.

Zhiwu Yu,Fa-xing Ding,C.S. Cai +2 more
TL;DR: In this article, an experimental study on the behavior of CFT stub columns with self-compacting concrete (SCC) and normal concrete (NC) concentrically loaded in compression to failure was presented.
Compressive behavior of circular GFRP tube-confined UHPC-filled steel-encased stub columns
TL;DR: In this article , the axial compressive behavior of FUSCs was investigated, in which the thickness and fiber winding angle of FRP tube, section size of profile steel, and substitution rate of coarse aggregate were the variables considered.
