Hassan al-Karawi

Doctoral Student at Structural Engineering

Hassan is a doctoral student at the division of structural engineering, in the research group lightweight structures. Hassan’s main research interest is fatigue of welded steel structures and maintenance methods.

Many bridges in the world have reached, or exceeded, their design fatigue life. It is a challenge for society to wisely manage this huge asset of old bridges. Replacing bridges because their theoretical life span is reached is not a sustainable solution, neither from societal nor economical point of view.
