FEA Aspects of the Local Bending stresses at the HEA-section Runway Beams

Abstract

This paper deals with the local bending stresses at the steel runway beams made of HEA sections. Some aspects of this structural problem are considered here, with usage of finite element analysis (FEA). There are presented three different models and several load cases to obtain the values of local bending stresses which enable the comparison with the results from adopted EN regulative. Specially, it is considered the possible superposition of stresses for adjacent wheel loads. This is done due to restriction in regulative which deals with the geometry of trolley vs. beam width. It is confirmed some inconsistencies in current regulative, along with the occurrence of affected zone in section with possible higher values of stresses near the web. Without consideration of volume, it is noted that distance of adjacent wheels has influence on the level of local stresses.
