Key considerations for assessing structures at the accidental limit state in fire

Most structures in Europe are constructed using limit state design methods. Most of these structures are protected against some form of specified fire scenario. However, only a small minority of projects link these two major considerations together to form part of a unified structural fire design process.

The Eurocodes provide designers with the necessary procedures to undertake an accurate and economical structural fire design, yet few engineers ever consider undertaking such an assessment.

This article will focus on the load actions and combinations to be considered that enable the engineer to perform an adequate structural assessment for the accidental limit state in fire. It will also cover important considerations to ensure that any structural fire engineering strategy is appropriately aligned, and the key information is available within the contract chain to facilitate this performance-based approach.
