Abstract

The chapter presents a hierarchical system of calculation methods for assessing the fire resistance of reinforced concrete slabs upon the onset of the limit state of loss of integrity. Three approaches are proposed: tabular, simplified and refined. The tabular method allows to quickly assess the fire resistance of slabs, the simplified method takes into account structural parameters and loads, and the refined method takes into account detailed characteristics of materials and temperature effects for the most accurate results. Such a system provides designers with flexibility during the design phase, allowing them to select the appropriate method depending on the required accuracy and available data. In addition, they help increase the safety of building structures during a fire.
