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