Finite element analysis of the flexural behaviour of steel-reinforced GEM-TECH cementitious material

This paper presents a numerical investigation on the flexural performance of a novel cementitious reinforced GEM-TECH material using finite element method. A discrete nonlinear FE model using the commercial software ANSYS was employed to model a steel-reinforced GEM-TECH beam. | Finite element analysis of the flexural behaviour of steel-reinforced GEM-TECH cementitious material Engineering Solid Mechanics 6 2018 263-274 Contents lists available at GrowingScience Engineering Solid Mechanics homepage www.GrowingScience.com esm Finite element analysis of the flexural behaviour of steel-reinforced GEM-TECH cementitious material Ucheowaji Ogbologugo Messaoud Saidani Adegoke Omotayo Olubanwo and Eoin Coakley School of Energy Construction amp Environment Coventry University Coventry West Midlands UK A R T I C L EI N F O ABSTRACT Article history This paper presents a numerical investigation on the flexural performance of a novel Received 10 January 2018 cementitious reinforced GEM-TECH material using finite element method.

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 .
