SR65 Modelling fire behaviour of metal pipe penetrations through concrete walls (2007)

The objective of this project was to model the behaviour of pipe penetrations as they pass through fire-rated concrete walls so that the amount of full-scale testing required can be reduced, greater extrapolation of results can be made and non-standard fire scenarios can be considered.

The development of a (NISA) computer model to simulate heat flow in a pipe-penetrated concrete wall during a fire is described, and comparisons are made between predictions and experimental results.

The results of two full-scale fire tests using a total of 14 pipes and over 200 thermocouples are presented. These tests were performed to provide a database to assist the modelling. Variables were pipe diameter and thickness, pipe material and seal type.
