Abstract : The behavior of reinforced concrete slab exposed to fire is presented. Two stages of analysis is carried out using Finite Element package ABAQUS to find thermal response of structural members namely thermal analysis and structural analysis. In the first step, the distribution of the temperature over the depth during fire is dete rmined. In the next step, the mechanical analysis is made in which these distributions are used as the temperature loads. The responses of structure depend on the type of concrete and the interactions of structural members. The RCC slab were modeled to sho w the role of slab thickness, percentage of reinforcement, width of slab and different boundary condition when expose to fire loading. Effects for both materials in RCC slab at elevated temperatures are also evaluated.
