Strucutal specialists at World Trade Center site after 9/11 attacks

The video tutorial discusses the assessment of building structures for safety and accessibility, focusing on identifying building types and their associated failure mechanisms. It explains the concept of pancake collapse, using the World Trade Center as a case study, and highlights the impact of such collapses on adjacent structures. The tutorial also covers soft story failures, drawing parallels with the San Francisco earthquake, where weaker lower levels led to building collapses.
