This paper reports the results of experimental and numerical investigations of the behaviour of high performance lightweight concrete (HPLWC) hollow core slabs under fire conditions. A series of full-scale furnace tests has been performed to assess the slabs’ load bearing capacity under fire conditions along with the characteristics of the thermal field. Numerical simulations of the heat diffusion process were also carried out using a finite element model of the panel cross section. The ultimate strength was evaluated according to the advanced calculation methods suggested by the Eurocodes, using decay laws of the mechanical properties found in literature. The comparison between the experimental and numerical investigations gave insight into the fire performance of HPLWC hollow core slabs and enlightened on the phenomena governing their fire resistance.

Abstract
This paper reports the results of experimental and numerical investigations of the behaviour of high performance lightweight concrete (HPLWC) hollow core slabs under fire conditions. A series of full-scale furnace tests has been performed to assess the slabs’ load bearing capacity under fire conditions along with the characteristics of the thermal field. Numerical simulations of the heat diffusion process were also carried out using a finite element model of the panel cross section. The ultimate strength was evaluated according to the advanced calculation methods suggested by the Eurocodes, using decay laws of the mechanical properties found in literature. The comparison between the experimental and numerical investigations gave insight into the fire performance of HPLWC hollow core slabs and enlightened on the phenomena governing their fire resistance.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
