Shear behaviour of sandwich panel fasteners in fire

Popis výsledku v původním jazyce

In recent years the usage of sandwich panels as wall cladding and roofing has increased sig-nificantly. It has been shown that by using sandwich panels and trapezoidal sheeting as a sta-bilizing members, a considerable amount of savings of steel can be achieved for structural members at ambient temperature. Previous researchers has not covered this topic under elevated temperature and these stabilising effects may also help to achieve similar savings in case of fire. The behaviour of sandwich panel stiffeners in fire is very important in order to predict and investigate the whole structure. Therefore, an experimental investigation was conducted to study the shear behaviour of sandwich panel joints in fire when loaded in shear under the diaphragm action. In this paper the experimental results of 16 sandwich panel fastener tests are presented which are carried out under the RFCS research project STABFI which is performing a research currently on the stabilization of a structural building using the cladding systems in fire. The results of the tests show that bearing failure of the inner steel sheet was the main failure mode. There was no failure of screws for all the tests at ambient and elevated temperatures except one. The results of the tests provided experimental data for the sandwich fasteners related to building stabilization in fire through the cladding systems which is under investigation of RFCS project STABFI.
