KTH Royal Institute of Technology is a public university in Stockholm, Sweden. It was established in 1827 but origins back to 1697 when Laboratorium mechanicum was established by the Swedish scientist and innovator Christopher Polhem. KTH is ranked 73 in the world among all universities and 44 in the subject of Civil and Structural Engineering, according to the 2024 QS World University Rankings. KTH has 5 campuses with a total of over 13 000 full-time students, 1 700 PhD students and 3 600 full-time equivalent staffs. 

The Division of Structural Engineering and Bridges is led by Prof. Raid Karoumi and consist of 2 full professors, 2 associate professors, 3 researchers and 10 PhD students. The research consists of both experimental, numerical and theoretical work and covers several areas related to railway bridge dynamics, train-track-bridge interaction, soil-structure interaction, traffic induced vibrations, reliability-based assessment of railway bridge dynamics, footbridge dynamics, innovative design of steel bridges and components, fatigue and conditional assessment of bridges, AI- IoT and image recognition techniques for bridge assessment. 

The division has participated in several international research projects, such as the 6th Framework EU project Sustainable Bridges, the RFCS project ELEM – Composite Bridges with Prefabricated Decks, the Scandinavian project ETSI – Bridge Life cycle Optimisation, the Marie Curie project Long Life Bridges, the 7th Framework EU project CAPACITY4RAIL, the EU Shift2Rail projects In2Smart, In2Track, In2Track2 and In2Track3, and the EU-Rail project IAM4RAIL.
