Thermomechanical modelling of sandwich panels with connections in fire resistance tests

This paper presents two full-scale fire resistance tests of sandwich panels with connections, to verify one way coupled fire-structure simulations. The heat transfer simulations agree well with the tests, however, the structural response simulations show some differences compared to the start of the first test, which is a sandwich panel façade....

Insulation pyrolysis for sandwich panel fire-structure simulations

A sandwich panel, as a very important component in building façade systems, consists of two thin walled plates plus an insulation core. For this core, traditionally materials like mineral wool have been used. However, polymer composites are increasingly used instead, for among others their higher stiffness, and better resistance to wind and...

Implementation of a pyrolysis model in two-way coupled fire-structure simulations

Two-way coupled CFD fire and thermomechanical FE analyses of a self-supporting sandwich panel facade system

A self-supporting sandwich panel facade system under fire is studied. First, a thermomechanical FE model, which comprises the complete facade system, and incorporates material degradation and geometrical nonlinear behaviour except for the insulation material and connections, is loaded by a fire temperature curve. Eurocode design rules then...
