Element SOLID65 was used to model the cementitious material 10 May 2018 Keywords while LINK180 element was used to model the reinforcing bars and stirrups. For model FEA validation FEA results and crack plots were compared to those obtained from the experimental ANSYS results of five reinforced GEM-TECH beams three beams designed with target density of 1810 Failure kg m3 and two beams with target density of 1600 kg m3. Both load-deflection plots and the Crack failure mode crack plots predicted by the FE model were in good agreement with the Propagation experimental results. GEM-TECH 2018 Growing Science Ltd.

Introduction The application of lightweight cementitious structural materials in high-rise buildings such as residential and other complexes would reduce the dead weight of these buildings on their foundation Kosmatka et al. 2002 . It would also reduce the effect of seismic and wind loads in earthquake prone areas Lee et al. 2014 as the effect of the force is a function of the mass of the structure and the acceleration due to gravity which .
