Steel and reinforced concrete bridges and overpasses are vulnerable to fires caused by many events such as car fires, tanker truck accidents, wildfires, arson, or terrorist act. The first part of the webinar discusses fire effects on bridges with steel superstructure and steel, reinforced concrete, or composite piers and how such bridges are protected against fire effects. The second part of the webinar focuses on engineering ethics. It shows the 3rd Canon of the NSPE Code of Ethics for Engineers, which states, "Engineers shall issue public statements only in an objective and truthful manner,” and the 5^th Canon, which states that “Engineers shall avoid deceptive acts,” appears to have been grossly violated during the construction of the replacement spans.

Learning Objectives:

• How fires affect steel bridges.
• What are the concepts and types of fire protection used to prevent the fire collapse of bridge spans?
• The fire hazard in steel bridges.
• The case of the fire collapse of Mac Arthur Maze spans.
• Canon 3 of the NSPE Code of Ethics for Engineers states that “Engineers shall issue public statements only in an objective and truthful manner.”
• Canon 5 of the NSPE Code of Ethics for Engineers states, "Engineers shall avoid deceptive acts.”
• How it appears that the Canons 3 and 5 above have been grossly violated during the construction of the replacement spans
