ISO/TR 24679-4:2015 provides a fire safety engineering application relative to fire resistance assessment of an open car park according to the methodology given in ISO/TS 24679. It describes the adopted process which followed the same step by step procedure as that given within ISO/TS 24679. The annexes of ISO/TR 24679-4:2015 presents the detailed numerical analysis results obtained for most severe fire scenarios on the basis of this specific fire safety engineering procedure for open car parks.

Abstract

Overview

ISO/TR 24679-3:2015 is a Technical Report demonstrating the ISO/TS 24679 fire resistance assessment methodology through a worked example: a largely ventilated open car park. The report illustrates a step‑by‑step fire safety engineering process for quantifying structural performance in real fire scenarios, emphasizing localized heating, global structural behaviour, and 3D numerical analysis of a composite steel–concrete floor system. It is intended as an application example of ISO/TS 24679 and includes annexes with detailed numerical results and drawings.

Key topics

Methodology demonstration: Applies the ISO/TS 24679 seven‑step design process (scope, objectives, trial design, design fire scenarios, thermal response, mechanical response, assessment and documentation).
Built environment characteristics: Example is a 3‑storey open car park with large façade openings and typical parking layouts; criteria for “open car park” (e.g., façade opening area) are described.
Fuel load and fire scenarios: Characterisation of car fire heat release based on real tests, selection of severe but realistic design fires (localized car fires, multiple car involvement).
Structural modelling: Use of global 3D finite element analysis for composite steel and concrete floors, considering load redistribution from heated to cold parts rather than single‑member resistance.
Performance criteria: Stability-focused targets such as no overall collapse; specific limits (e.g., maximum beam deflection ≤ 1/20 span, reinforcing steel strain
