Citigroup Skyscraper Design Problem

Sometimes structures have hidden weaknesses. In this video segment adapted from Building Big, William LeMessurier, the structural engineer who designed the Citibank Center (now called Citigroup Center), describes the decisions that placed his building and the city of New York in danger and those that corrected a potentially catastrophic design flaw. This resource is useful for introducing components of the Engineering Design (ETS) from the Next Generation Science Standards (NGSS) to grades 6-12 students.

This resource was adapted from Building Big: "Skyscrapers."
