Progressive collapse, also known as disproportionate collapse, is a critical structural failure mechanism that may begin with the loss of a key structural component, such as a column or connection, and can lead to partial or complete failure of a structure.

Dr. Pirmoz has extensive experience in nonlinear progressive collapse analysis. His article, published in The Structural Design of Tall and Special Buildings, was among the early studies on this subject.

Progressive collapse evaluation requires a deep understanding of structural mechanics, extreme material behavior, and advanced computational modeling knowledge to simulate structural response, interpret analytical results, and develop practical engineering conclusions for design.
