Optimization of Building Floor Beam Layout by Optimization Algorithms Regarding the Concrete Printing Techniques (2022-09)¶

New manufacturing technologies, including robotic printing and robotic CNC, ease the construction of structural elements with unique optimum geometries. Robotic manufacturing technology, unlike classical methods, can be utilized to produce distinctive structural elements (e.g. unparalleled crossing beam layout) or change beams' sections (non-prismatic sections). On the other hand, the complicated analysis and design of distinctive elements with changing sections demand the development of a new optimized technique. To describe the potential and application of these techniques, the optimization of a building's floor's beam layout as the example was selected. The capabilities of the concrete printing technique as the optimization constraints were considered. This study designed and analyzed a wide range of layouts (No.61), respecting engineering judgment. Based on two of the superior layouts by, three optimization approaches were optimized, the coordinate of the nodes (Cx,y), the connectivity order (CO), the beams, and their combination were respectively regarded. Optimization and analysis tools were developed through an interface between analysis software and coding platforms to utilize the capability of the particle swarm optimization algorithm and valid analytical results for an adaptive optimization technique. This study, along with addressing optimum floor layouts and optimization techniques, displays the robotic concrete printing process by printing an optimum layout.
