Gaisro temperatūra paveiktų gelžbetonio plokščių elgsenos netiesinė analizė baigtinių elementų metodu
Santrauka
A coupled analysis using software package DIANA has been carried out. The aim of this work is to show the behaviour of reinforced concrete structure exposed to fire in order to obtain the critical collapse time. The reliability of a fire analysis results is strongly affected by the choice of the constitutive laws of materials and the values of their thermo-mechanical parameters. In the present numerical model, the material properties are considered to be temperature-dependent. The constitutive relationships are based on Eurocode 2 specifications [1] and recommendations [2, 4].
