Abstract:Purpose
The collapse of a structure resulting from the instability of steel frames due to fire is the worst failure mode to consider in fire-structural engineering, and should be avoided. The purpose of this paper is to propose a new method for estimating the minimum possible duration of a fire event that could result in the instability of an unbraced steel frame.
Design/methodology/approach
The proposed method is in the form of a constrained minimization problem that determines the worst case fire scenario … Show more
