Stress Analysis of Steel Structure Comprising Cylindrical Shell with Billboard Tower
Апстракт
In accordance with EN1993-1-1, in the definition of element classes, the tubular cross section elements are considered as class 3 for cross section that respects the relation: d/t lt = 90 epsilon(2). If for any cross section this relation is not satisfied, the norm is not valid and the cross section is classified as a curved thin walled element - shell element. Thus the design is done according to EN 1993-1-6 normative. The paper presents some aspects regarding the shell design for a case study - a 30 m tall billboard pillar. The designing process is detailed in regard to the used analysis and the ultimate limit states checking. Considering the high stress concentration in the area of the segment joints, design of welded joints is also presented. The Finite Element Method (FEM) is applied as well, showing results in agreement with analytical ones.
