PROGRESSIVE COLLAPSE
OF BUILDINGS
- Developed fast-running, physics-based
simulation of progressive collapse of steel buildings (ANSYS/ LS-DYNA),
- Established energy-based analysis of
disproportionate collapse,
- Performed sensitivity analysis to stiffness of
slabs and beam spans,
- Assessed effect of geometric imperfections on
the building dynamic stability,
- Developed
probabilistic characterization of building resistance to
disproportionate collapse, considering multiple scenarios of local
failures.

SEISMIC ANALYSIS
- Conducted time-history simulations of
archetypical steel buildings under devastating earthquake motions,
- Evaluated post-earthquake damage to the load
carrying
members, and retrieved slab accelerations and inter-story drifts for
evaluation of nonstructural damage,
- Mentored graduate students working on estimates
of casualties, and agent-based evacuation models.

 | METALLIC WOVEN MATERIALS
- Developed simulations of frictional damping
(LS-DYNA),
- Identified deromation mechanisms that produce frictional sliding and contribute to the energy dissipation.
