Commentary on Eurocode 4 Part 1-1 for Composite Steel and Concrete Structures

Prof. Dr.-Ing. Gerhard Hanswille is a partner at HRA Ingenieurgesellschaft in Bochum and a checking engineer for structural design. Up until 2017 he was the managing director of the Institute of Structural Engineering at the University of Wuppertal and professor for steel and composite structures. He is a member of the North Rhine-Westphalia Academy of Sciences and was chair of the DIN working committee for composite construction from 1993 to 2018, also a member of the DIN EN 1994-1-1 and DIN EN 1994-2 project teams during that time. This publication benefits from his experience gained with several advisory bodies and DIN working committees, the German Institute of Building Technology (DIBt), the Federal Railway Authority (EBA) and the Federal Ministry of Transport and Digital Infrastructure (BMVI).
Main fields of work: Research studies in the field of steel-concrete composite construction with a focus on composite technology, life cycle analyses and structural stability. Besides projects involving buildings and industrial structures, in recent years he was active as a structural and checking engineer for larger steel and composite bridge projects.

Prof. Dr.-Ing. Markus Schaefer was appointed ?Full Professor of Structural Engineering and Composite Structures? at the University of Luxembourg (Department of Engineering) in 2017. The period between gaining his doctorate in steel and composite construction at the University of Wuppertal in 2007 and his professorial appointment was filled with international engineering activities as technical director of Spannverbund S. A., as ?Directeur des Etudes? at CLE S. A. and teaching activities as a university lecturer. He is currently deputy chair of the DIN Eurocode 4 mirror committee and a member of CEN/TC250/SC4 and other national and European working groups for composite construction. As part of the EU mandate M/515, he is also currently involved with drafting the second generation of EN 1994-1-1 as leader of the CEN/TC250/SC4.T6 project team.
Main fields of work: Research studies in the field of steel-concrete composite construction with a focus on composite/slim-floor beams, shear connectors, composite columns and the use of high-strength materials. In addition, he is heavily involved in standards development. In recent years he participated in the design and construction of many steel and composite structures.

Dr.-Ing. Marco Bergmann is an engineer at HRA Ingenieurgesellschaft in Bochum. He gained his doctorate in the structural fire design of composite columns at the University of Wuppertal in 2011. He has been a member of the DIN working committee for composite construction since 2015 and for many years has served as a lecturer for the Real Estate Management and Construction Project Management (REM + CPM) course of study at the University of Wuppertal.
