Wabenträgersysteme aus Stahltrapezprofilen

Honeycomb girder systems made of trapezoidal corrugated steel sheets.

This paper deals with the load carrying behavior under bending of honey comb girder systems. Honeycomb girder systems are a newly developed construction solution for the cladding of roofs and facades of industrial steel-framed buildings. They consist of a mirror-symmetric arrangement of trapezoidal corrugated steel sheets connected with mechanical fasteners. This construction solution allows an increase of the steel frame distances from 6 m to 9 m up to 15 m. Experimental and numerical investigations, which have been carried out, are discussed. Based on numerical parametric studies the maximum characteristic distributed load and the effective bending stiffness of honeycomb girder systems with varying practically relevant geometric boundary conditions are determined. A design concept was developed and applied to the results of numerical parametric studies. The use of practical design tables is explained by a worked example.
