CHICAGO, Feb. 4, 2005 -- A new report by Nestor Iwankiw of Hughes Associates and Larry Griffis of Walter P. Moore & Associates provides a unified structural engineering review and objective assessment of the structural performance of major multi-story building collapses in the U.S. due to the extreme exposures of blast, impact, and fire.
The report, "Comparison of Structural Performance of Multi-Story Buildings Under Extreme Events," focuses on:
-- The 1993 bombing of the World Trade Center (WTC) towers in New York City;
-- The 1995 bombing of the Murrah Federal Building in Oklahoma City;
-- The Sept. 11, 2001 attacks on the World Trade Center towers and collateral damage of surrounding buildings in New York City; and
-- The Sept. 11, 2001 attack on the Pentagon in Washington, D.C.
In addition, a historical survey on the performance of multi-story buildings under normal fires is presented for comparison to these extreme events.
"This document is important because it clarifies issues in an honest way and demonstrates that all materials are equally safe when designed properly and in accordance with today's building codes," according to Charles J. Carter, chief structural engineer with the American Institute of Steel Construction.
