Abstract: With the increasing use of fasteners in the field of civil-engineering the need to estimate the fire resistance of these connections is obvious. Different test procedures for fire tests and no commonly accepted rules to design fasteners for this use show the problems in present. Scientific work to estimate the different failure modes known from tests with ambient temperature has been missing so far.

To investigate the fire resistance of fasteners several numerical simulations were performed. Programs have been developed to calculate temperature fields for fasteners in concrete and to calculate stress-strain relationships in concrete slabs in bending and under fire load. Qualified non-linear finite element programs have been extended to calculate concrete cone failure in case of fire. To check the numerical simulations several large scale fire tests with fasteners installed in loaded concrete slabs were done.
