Multi-objective truss structural optimization considering natural frequencies of vibration and global stability

作者：

Highlights：

• Problems considering weight, natural frequencies of vibration and global stability.

• Global Stability set for the first time in the literature as an objective function.

• The Third Evolution Step Differential Evolution (GDE3) is the search algorithm.

• Sizing, shape, and layout truss structural optimization problems are investigated.

• A strategy is applied to extract solutions from the Pareto-fronts.
