Flexural strength of concrete-galvalume composite beam under elevated temperatures
Agus Maryoto, Han Ay Lie and Hendrik Marius Jonkers

 
Abstract
    In this paper, the elevated temperature on a concrete-galvalume composite beam's flexural strength based on the numerical and experimental methods is investigated. The strategy is to perform modeling and simulation of the flexural test based on finite element method (FEM) at room temperature and validate its results by using experiments at the same temperature. With material constants and boundary conditions set-up provided from the validation, we model and simulate the same flexural tests for the composite at higher temperatures. The study concludes that the flexural strength of the beam decreases at higher temperature. Additionally, it was shown that cracking moments is very sensitive to the temperature fluctuation and the failure modes are sensitive with respect to the elevated temperature.
