Lateral Load–Displacement Behaviors of Reinforced Geopolymer-Concrete Column Using Finite Element Analysis
Today the use of environmentally friendly building materials in construction is considerably important, such as geopolymer concrete. Geopolymer concrete uses by-product material, such as fly ash instead of cement. Some aggressive materials in the environment, such as seawater and soil with high sulfate content, attack ordinary reinforced concrete structures. In such aggressive environments, structures on the basis of geopolymer reinforced concrete are preferable because previous studies showed that geopolymer reinforced concrete has ability to survive in those corrosive environments. This paper discusses finite element analyses on a reinforced geopolymer concrete column to predict their lateral load–displacement behavior using ABAQUS software. Mechanical properties of geopolymer concrete such as stress–strain relation, modulus of elasticity, and Poisson Ratio need to be determined as an input in the finite element analyses. For the validation purpose of the analyses, a previous experimental test result of a reinforced geopolymer concrete column having a cross-section of 175 square mm, 1500 mm high and of slender type was used. Three types of eccentric load were examined. It is found that by appropriate determination of the geopolymer properties, the finite element analyses using ABAQUS can predict the lateral load–displacement behavior of the slender column significantly.
