Kareem - 2019 Best Paper in ASCE’s Journal of Structural Engineering (Structural Hazards)

April 9, 2020

The NHERI SimCenter directors are very pleased to congratulate Ahsan Kareem, a co-PI at the SimCenter and the Robert M. Moran Professor of Engineering in the Department of Civil & Environmental Engineering & Earth Sciences at the University of Notre Dame, on his most recent honor. Ahsan is the lead author of the Journal of Structural Engineering’s 2019 Best Journal Paper in Structural Hazards. This honor, like many others he has received over his career, is a testament to his insight into structural engineering in the face of wind hazards.

Ahsan, commenting on the award-winning paper, notes that “I believe it is a very topical area as we move in our design practice to accommodate non-stationary effects from wind events, like thunderstorms or tornadoes, that raise havoc in our communities. All current codes and standards are based on stationary analysis. The beauty of the non-stationary Generalized Loading Chain presented in the paper is that it seamlessly reverts back to a stationary case of Davenport Loading Chain for conventional winds. In other words, these approaches are bound mathematically and do not rely on empiricism.”
