Steel corrugated web girders are increasingly used in buildings, industrial halls and bridges due to their well-known advantages. Numerous researchers highlighted and studied the advantages and favorable properties of the trapezoidally corrugated web girders in the past. However, there are only a limited number of available design proposals for the resistance calculation of trapezoidally corrugated web girders. The current research focuses on the authors’ contribution to recover this lack of information and to improve the economic design of corrugated web girders. In frame of the research activity standard conform design procedures are developed providing both analytical resistance models and proposals for FEM based design approaches for the design of corrugated web girders. The design proposals are developed based on comprehensive experimental, analytical and numerical studies. The current paper collects and introduces the completed and on-going research activities and the improved design proposals developed by the BME Department of Structural Engineering within the last 10 years.
