Optimization of hybrid I-beams using modified particle swarm method

Инженерно-строительный журнал, 2018
An approach for the optimization of hybrid welded I-beams based on the modification of the particle swarm method is proposed. A solution search is performed on discrete sets of variable parameters, which are taken as the size of sheets of rolled steel ...

STATIC AND DYNAMIC ANALYSIS OF STIFFENED PLATE USED IN MACHINE TOOL COLUMN

Journal of Engineering
Static behavior (under torsion and bending loading) of machine tool column was studied in this paper. The effects of changing the cross sectional area of the column itself on the deformations (design parameters) was investigated.

Finite Element Analysis to Determine the Optimum Stiffener Spacing on Barge Deck with 5-15-5 Sandwich Plates

Kapal
The application of sandwich plates in marine structures provides a lightweight yet strong alternative to conventional steel plates. This study investigates the extent to which stiffener spacing on barge decks can be increased when using 5–15–5 mm ...
