DELTABEAM® composite beam with CLT slabs REI90 fire test and charring test

Peikko has been investigating the performance of the joint area between DELTABEAM® Composite Beam and timber floors, as a hybrid slim floor structure is getting a more popular solution. Charring test and 90-minute fire test with loading were performed for DELTABEAM® Composite Beam with CLT slab structure. The tests proved that DELTABEAM® used with CLT slabs works in fire situations without any additional fireproofing under the beam or the CLT slab. DELTABEAM® allows leaving the CLT slabs exposed. DELTABEAM® enables the creation of a slim floor structure while simultaneously joining the beam and CLT slab together with encapsulated transverse reinforcement.
