Trapezoidal sheeting made of stainless steel can be used for applications with high requirements on visual appearance or corrosion resistance. The calculation of the load-bearing capacity of thin-walled structures including trapezoidal sheeting normally follows the procedures of EN 1993-1-3 and similar codes. EN 1993-1-4 complements this standard concerning thin-walled structures made of stainless steel. This standard relies on many publications on thin-walled structures made of stainless steel. But unfortunately these publications almost all focus on thin-walled beams and columns and therefore some topics that are specific to trapezoidal sheeting are not recognized.
The results of the presented research results on the load-bearing behaviour of thin-walled trapezoidal sheeting made of stainless steel are closing this gap: With the proposed additions to the existing design formulae, the complete calculation of the load-bearing capacity of trapezoidal sheeting made of stainless steel is possible.
