Abstract

NLFEA conducted to simulate simply supported reinforced concrete beam over their depth with temperature differentials tested at room ( 15oC ) and low temperature ( 25oC ).Three dimensional FE modals were developed to verify geometry, material, loading, boundary conditions and temperature profile. The results are verified against experimental values in terms of cracking loads, yield loads and cracking pattern. The validated NLFEA models are explored with same beams, uniform temperature as well as statically indeterminate reinforced concrete with or without temperature differentials. The values were capable of predicting the ultimate strength at both room and low temperature. In addition to this, it was observed clearly indeterminacy of fixed ends increases the strength of reinforced concrete beam ( upto 110% ). NLFEA showed that low temperature increases the strength of beam without stirrups.
