Abstract:
In recent years, monolithic building solutions' durability, energy efficiency, and aesthetic appeal have contributed to their increasing popularity. However, it is crucial to diligently engineer these structures to prevent potential failures under various loads. The present work explores the engineering study of designing monolithic dome components using Aluminium 6082-T6 alloy. Material testing and connection moment capacity in semi-rigidly jointed structures are examined using experimental and finite element analysis (FEM) approaches. Two single-layered reticulated dome types of geometric and material nonlinear analysis (GMNA) were conducted. The domes were rigidly and semi-rigidly connected by incorporating Aluminium connection bending stiffness in an accurate and valid program. The resulting loads were used to determine the strength of the columns of the reticulated members of the dome. The coefficient of strength calculated was compared with the stability coefficients from different codes. This work also focuses on dimensioning structural elements under combined bending and buckling forces. It emphasizes incorporating second-order effects, buckling susceptibility, and spatial changes in axial force and flexural rigidity for accurate dimensioning. The proposed dimensioning criterion ensures the appropriate utilization ratio of the section by considering safety coefficients and critical loads.
