MTA-BME Lendület New Generation Steel Bridges Research Group

Introduction


The construction industry, and particularly the steel bridge industry, is going through a significant change primarily due to three coincident circumstances: (i) Industry 4.0 and digitalization of the construction industry has fundamentally changed not only the industrial but also the traditional design/manufacturing processes; (ii) appearance of new materials and manufacturing methods; and (iii) the appearance of new bridge types. The new developments in the fields of material science, manufacturing technology, design theory and structural systems are producing a new generation of steel bridges. The altered circumstances in the design and manufacturing require the revision of the traditional design methods and renewal of design theories. The research aims to investigate and renew the design methods and theoretical background of the new generation steel bridges accounting for innovative steel materials, structural solutions, and manufacturing techniques. Please find attached a flyer for collaboration in Horizon 2020 research and innovation proramme here.

 

Aims


The research program focuses on the following four research fields: (i) design theories utilizing high-strength steel structures as innovative new material for steel bridges, (ii) consideration of new manufacturing methods and their specialties in design theories, (iii) numerical model-based design of steel structures as improvement possibility of traditional design methods, and (iv) design theory development for new structural systems using new technical solutions. The main goal of all the four research fields is the implementation of the new achievements and developments of the steel constructional industry into the basic design theories. Therefore, all the separated research topics represent significant steps of a larger research work and have in common to improve the economy of the new generation steel bridges by introducing improved or new design theories ready for industrial application.
