ABSTRACT
This chapter presents four examples showing how a complete structure can be analised in fire situation using the concept of sub-structure analysis or element analysis. The first example shows how a single span is extracted from a continuous beam
allowing a member analysis by the simple calculation model. The discussion illustrates the concept explained in Section 5.1.2. The second example illustrates the same concept for extracting a sub-structure from
amoment resisting frame allowing analysis by the advanced model of the sub-structure instead of the complete structure. The third example presents the steps to be followed when designing a hypothetical
industrial building, using the simple method for the verification of the elements. The last example presents a case study of a particular building: a high-rise rack steel
structure supporting the building envelope. Due to the complexity of the structure, sub-structures have also to be defined, those being analyzed by an advanced model. The discussion here encompasses also the decisions that were taken for representing the fire exposure.
