Abstract: Thermal behavior of structural members has become a topical interest with in field of civil engineering due to the major fire accidents in buildings. The thermal behavior of the structural members subjected to thermal conductivity will give an overview about how they react with temperature. Concrete elements exposed to fire, as a result it undergoes spalling and exposing steel reinforcement. The experimental study on the behavior of structural members is hazard, costly and time consuming. In this work finite element modeling was carried out for Normal and Self Compacting concrete beams under elevated temperatures. Finite element modeling of the beams was done using ANSYS 11 software. These beams were heated as per IS3809 Time- Temperature curve. This study is extended for different grades of concrete such as M25, M30, M35, M40 and different nominal cover as per IS 456-2000. Reduced strength and increased deflection was observed on temperature loads, the changes in behavior of Normal and SCC beams on temperature loads. It was observed from the analysis that when the grade of concrete increases the reduction in strength also increases.
