Mechanical analysis of steel beam protected by OSB
Original language description
An unprotected steel structure in a fire does not exhibit significant fire resistance. Very often, structural collapse due to excessive deflections occurs within 15 minutes. Fire cladding by OSB appears to be the most environmentally friendly option. Wood in a fire, despite its flammability, is very good at resisting fire, and like char layer is a great insulator. This article focuses on the influence of standard values for the calculation of steel beam displacement. For validation, a large-scale experiment was performed on three steel beams, unprotected, protected by a single-layer OSB cladding and by a two-layer OSB cladding. Experiments have demonstrated the good functionality of the OSB cladding as a fire protective layer. This article presents the influence of input data on the correct approach to mechanical modelling and simulation of steel beam displacement. Experiments have shown the evolution of steel beam deflections. The article recommends sources for input data for simulations up to 600 °C and contemplates further necessary research for modelling.
