Thermomechanical modelling of composite slab joints under fire

Sue Ellen de Nijs investigated in this master research the influence of a thermal action caused by fire on composite slab joints in precast floors.

The main question was whether or not the joint is critical in a combination of mechanical load and thermal load. Sue Ellen compared the Eurocode to a numerical thermomechanical simulationmodel, taking into account several joint widths. The expectation was that the joint would be a mechanical weak link, but the master theses shows that the influence of the joint is limited.
