DETERMINATION OF MECHANICAL STRENGHT AND STABILITY OF AN EXPO PAVILION MADE FROM METALLIC STRUCTURE

Abstract

In the present paper was conducted a study of the resistance and rigidity of a metallic structure placed in the city of Galaţi. The metallic structure studied can be made of unremovable joints or removable systems. It was used as basic elements with trellis girder substructures that provide increased rigidity and reduced weight. Topological optimization of the plate structure highlighted the possibility of using trellis girder elements for basic substructures. Compared from the point of view of the stiffness/mass ratio, several types (3 cases) of trellis girder were considered by choosing the constructive variant with the best ratio. From the resistance study resulted information for the calculation of the foundation on which the structure is located, especially the reactions in the links of the structure, forces and moments corresponding to the most adverse load situations.
