Progressive Collapse and Extreme Events

Our research interests in this area are related to the high-fidelity computational simulation of large scale infrastructural systems subjected to extreme manmade or natural hazards. In particular, we are interested in developing novel computational methods for simulation of collapse and failure of large scale infrastructural systems.

Areas of interest:

Simulation of failure in structural systems.
Constitutive modeling for material failure simulation in large scale systems.
Nonlocal multiscale beam models for simulation of failures.
Structural system optimization for progressive collapse prevention.
Sacrificial cladding systems for blast/impact mitigation.
