Cold-formed steel structures
TL;DR: The cold-formed steel structures are steel structural products that are made by bending flat sheets of steel at ambient temperature into shapes which will support more than the flat sheets themselves.

Optimal design of planar and space structures with genetic algorithms
TL;DR: An approach based on a proposed multilevel optimization is tested and proved to overcome this shortcoming and the main characteristic of the solution methodology is the use of a genetic algorithm (GA) as the optimizer.
