Specific Knowledge in Assessment of Local Fire for Design of Building Structures

Abstract

The development of designing building structures exposed to fire is solved not only on the basis of data obtained by standardized tabular values from the fire tests, but also by calculations or their combination with standard values. Calculation methods are becoming more important for most types of building structures, especially for timber and steel building structures. One possibility how to define thermal load of building structures, which is usable especially immediately after the development of a fire, is local fire method. This paper summarizes the principles of calculation while using local fire, it evaluates its positive and negative characteristics, and especially its practical applicability.
