Flame Size, Heat Release, and Smoke Points in Materials Flammability

August 1, 2008
Author(s)
Gregory T. Linteris, I P. Rafferty
The concept of using the flame size as a surrogate for heat release rate has been explored. A technique for simultaneously obtaining the heat release rate, flame size (height and area), and the smoke point of the flame solely from visual images has been

Mean Recurrence Intervals of Failure Wind Loads

August 1, 2008
Author(s)
Dat Duthinh, Joseph A. Main, Amelia P. Wright, Emil Simiu
The Commentary to the ASCE Standard 7-05 states that the nominal mean recurrence interval (MRI) of the wind speed inducing the design strength is about 500 years if the specified load factor is 1.5, as in early versions of ASCE 7, and somewhat higher than

Chapter 2Combustion Products and Their Effects on Life Safety

June 30, 2008
Author(s)
Richard G. Gann, Nelson P. Bryner
All combustibles produce heat and smoke that, in sufficiently high concentration, may be hazardous to life safety. Incapacitation can result from exposure to the asphyxiant gases, irritant gases, and heat. Irritant gases and visible smoke can reduce a
