Trapezoidal sheeting made of stainless steel two amendments to the design codes

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.
