TL;DR: The results show that 3DPC needs to meet the printability that it has higher requirements for rheology, hydration, and green strength than normal concrete, and the interlayer bond is the key to study the anisotropic strength and durability degradation.

TL;DR: In this article, the Particle Swarm Optimization (PSO) method was used to determine the flexural strength of CFS beam sections with the Eurocode 3 (EC3) geometrical requirements and with manufacturing and practical constraints.

TL;DR: In this article, a comprehensive investigation was conducted on the practical optimisation of CFS beams using a Particle Swarm Optimization (PSO) method, and six different CFS channel section prototypes were selected and then optimised with respect to their flexural strength, determined according to the effective width based provisions of Eurocode 3 (EC3) part 1-3.

TL;DR: In this article, the effect of initial geometric imperfections of the specimens measured by a specially designed set-up with laser displacement transducers were also taken into account, and the validated FE models and experimental results were then used to assess the adequacy of the effective width method in Eurocode 3 and Direct Strength Method (DSM) in estimating the design capacity of a wide range of conventional and optimised design CFS channel column sections.

TL;DR: In this paper, the results of a comprehensive experimental program aimed at studying the interaction of local and overall flexural buckling in cold-formed steel (CFS) plain and lipped channels under axial compression were presented.
