Computer Aided Design - Optimisation of Cross-Sections of Steel Profiles of Industrial Sliding Gate

Abstract

The paper presents optimisations of industrial sliding gate structure of 6 m wide. The optimisation process was carried out in two steps. In the first step, the structure of the gate was optimized due to its weight and the value of vertical displacement of the corner node of the gate. In the second step, the cross-section of the ground track of the gate was optimized. It was assumed that the gate is loaded with its self-weight and wind pressure. The calculations were made using computer-aided design. The following programs were used: SHAPE-THIN, Autodesk Robot Structural Analysis and ConSteel. The structures of the gate was made of SHS profiles. The ground track of the gate was made of cold formed profile, of sheet thickness 4 mm. All elements were made of S235 steel grade.
