Optimizing structural integrity in composite castellated beams through vertical stiffener plates Available to Purchase

This study investigates the structural behavior and optimization of hexagonal-shaped castellated beams with and without vertical stiffener plates. Traditional construction materials are considered for their potential to enhance the mechanical properties and sustainability of these innovative structural elements. Through a combination of theoretical modeling, numerical simulations, and experimental testing, this study aims to provide insights into the advantages and limitations of incorporating vertical stiffener plates in hexagonal castellated beams. The study commences with an exhaustive literature review, summarizing the current state of knowledge in the field of castellated beams and stiffener plate configurations. Using finite element analysis and physical ex- perimentation, the load-carrying capacity, deflection characteristics, and stress distribution patterns of these beams under various loading conditions was then analyzed. Different stiffener plate configurations are explored to optimize the design, considering factors such as size, spacing, and placement. The results of this investigation reveal the structural benefits of vertical stiffener plates in hexagonal castellated beams, including increased load-bearing capacity and reduced deflections, using conventional con- struction materials. Moreover, the study provides valuable insights into the design and placement of stiffener plates, contributing to the development of more efficient and sustainable construction practices. Key factors impacting beam behavior include beam height, number of openings, and shear connector size. The results show that vertical stiffener plates notably increase load-carrying capacity. The ratio of experimental to numerical ultimate load ranges from approximately 60% to 65%, highlighting substantial strengthening. The findings presented in this study offer guidance for architects and structural engineers in the innovative use of hexagonal-shaped castellated beams with vertical stiffener plates, advancing this area of the field of structural engineering.
