Causes and Prevention of Structural Failures
By: Ali K. Nessaee, PE, SECB
This presentation will provide a general overview of the causes and prevention of structural failures including errors in design, flaws in construction and /or materials, soil and foundation failure and failures due to natural forces such as wind and earthquake. Examples of each type of failure will be given, including some of the major catastrophic structural failures that were caused by human errors. Some of the major events to be covered are the Seongsu Bridge in South Korea in 1994, the Hyatt Regency hotel skywalk in Kansas city, Missouri in 1981, the Teton Dam in Idaho in 1976 and the Quebec Bridge in Canada in 1907 (and again in 1916).
Structural failure preventive methods and procedures such as quality assurance and proper coordination/communication during the design and construction that could have prevented these catastrophic failures will be discussed.
