Numerical fire resistance testing of lightweight concrete and normal weight concrete elements

This paper presents a numerical fire resistance testing of completely reinforced lightweight concrete and reinforced normal weight concrete structural members. The fire action is applied in accordance to normalized ISO-834 diagram. Thermal and mechanical properties of steel, lightweight concrete and normal weight concrete are linear for each level of temperature loading. The simple parallel fire test was done for the lightweight concrete material. The results show fire resistance of a few common cast structural elements like TT-plate, T and I beams, simple plate and wall panel made from lightweight concrete or normal weight concrete. These results can be taken as relevant engineers approval of fire resistance of tested member.
