Slender reinforced concrete column may fail in material failure or instability failure. Instability failure is a common problem which cannot be analyzed with first-order analysis. So, second-order analysis is required to analyze instability failure of slender RC column. The main objective of this study was to construct uniaxial interaction diagram for slender reinforced concrete column based on nonlinear finite element analysis (FEA) software. The key parameters which were studied in this study were eccentricity, slenderness ratio, steel ratio, and shape of the column. Concrete damage plasticity (CDP) was utilized in modeling the concrete. Material nonlinearity, geometric nonlinearity, effect of cracking, and tension stiffening effect were included in the modeling. The results reveal that, as slenderness ratio increases, the balanced moment also increases, but the corresponding axial load was decreased. However, increasing the amount of steel reinforcement to the column increases the stability of the column and reduces the effect of slenderness ratio. Also, the capacity of square slender RC column is larger than rectangular slender RC column with equivalent cross section. However, the result is close to each other as slenderness ratio increased. Finally, validation was conducted by taking a benchmark experiment, and it shows that FEA result agrees with the experimental by 85.581%.

Resumo Com o aumento do processo de urbanização e da população das cidades, surge a necessidade de entender o custo energético para produção dos materiais de construção. Entre os instrumentos utilizados, o aporte de energia é um importante instrumento no monitoramento do uso de fontes de energia não renováveis para produção de concretos convencionais, o que demanda novas pesquisas na área. Neste trabalho, um modelo híbrido ANFIS (Adaptive Neuro-Fuzzy Inference System) foi desenvolvido para predição do aporte de energia, para a avaliação da demanda de energia necessária para cada um dos componentes na produção de concretos convencionais (cimento, água, agregado miúdo e agregado graúdo), mediante a utilização de 101 dosagens experimentais, 101 dosagens para validação e coeficientes energéticos disponíveis em literaturas. Identificou-se que a escolha adequada da dosagem pode gerar uma economia no custo energético para produção do concreto da ordem de 24,77%, mantendo a característica mecânica de resistência à compressão para construções convencionais.
