On Fire-Proof Paint Thickness for Steel under Transient Fire

Abstract:

Fire-proof paint thickness is of importance to steel structure fire safety, and the common programme iteratively solves its heat conduction equation in fire-insistence test, while by dimensional analysis in the equation, this paper constructs a function of steel structure section-material grouped parameter, and also a similarity form is employed to form a relationship between any two different transient fires, then solves the grouped parameters in two other transient fires. Parameter comparisons among these 3 fires conclude: with the same fire time, fire-proof paint and size, fire-proof paint thickness is necessary to be the biggest in fire-insistence test, and smaller in site fire, and the smallest in t-square fire. The key factor to decide the thickness is surface temperature outside fire-paint. The common programme is with some redundance, and more reasonable guard should add to the steel structure in t-square fire. The foregoing analysis to fire-proof paint thickness by the function of steel structure section-material grouped parameter and the similarity form between any two different transient fires, broadens the common programme to any transient fires.
