DESIGN OF INDUSTRIAL HALLS WITH A STEEL STRUCTURE DUE TO AN ACCIDENTIAL DESIGN SITUATION - THE IMPACT OF A VEHICLE ON A FRAME COLUMN

Abstract

The article presents the effect of vehicle impact on the behaviour of the steel structure 
of an industrial hall. A portal industrial hall with a span of 18.0 m, a length of 42.0 m and a column 
height  of  7.0  m  was  considered.  The  spacing  of  the  frames  -  the  main  transverse  systems  -  was 
assumed equal to 6.0 m. The case in which a truck hits a frame column was considered. A scenario 
was assumed in which the impact occurs when the vehicle leaves the manoeuvring area located at the 
industrial hall. Therefore, according to EN 1991-1-7, the speed of the vehicle is 10 km/h. The weight 
of the vehicle was assumed to be 20000 kg. The direction of impact was assumed perpendicular to 
the side wall of the hall. The calculations were carried out in two stages. The first - optimization of 
cross sections of beams and columns in a permanent design situation. Static analysis was used. The 
second - determination of internal forces from impact in an accidental design situation. Dynamic 
analysis was used. Hall structural systems made of HEA, HEB and IPE sections were considered. 
The pinned and rigid connection of the column to the foundation was considered. The calculations 
were performed using Autodesk's Robot Structural Analysis 2024 computer software.
