BRE DG487/3 PDF

This Digest is part of a suite of related documents containing guidance for the construction industry on structural fire engineering design. The intention is to produce performance based guidance that brings together fire engineering and structural engineering providing a framework within which designers are free to develop site specific solutions based on real performance criteria. The Digests contain information complementary to the existing and emerging fire engineering codes and standards. Each Digest may be used in isolation or as part of the full integrated suite.

In this Part, three design methodologies for the fire resistance of masonry are described:

- traditional prescriptive, based on assumed worst-case test scenarios;

- simple performance-based, combining test-based and other data and extrapolating from test results;

- complete modelling of the fire process using fundamental physical data.
