The composite action ensures reliability as the system then behaves like one section under soil, experiencing traffic loads. The simulation on Dynamo BIM utilises the high-performance criterion of durability vs economy i.e. the opening dimensions and the length of the culvert is kept fixed and then one parameter e.g. minimum thickness of UHPC is defined, and the rest is optimized within the software. For each design point, the Dynamo model automatically computes concrete and UHPC volumes and their ratio, and updated the 3D solids of the concrete ring and UHPC shell in the next steps<\/strong><\/strong><\/p>\n\n\n\n This limits leakage, chloride ingress and loss of stiffness, especially for a 75\u2013100-year design life, as compared to the conventional culvert which has a reduced design life.<\/p>\n\n\n\n The culvert geometry is driven by six independent design variables<\/p>\n\n\n\n all other dimensions are computed in a single Code Block that encodes the shell-plus-core design rules.<\/em><\/p>\n\n\n\n Code Block:<\/p>\n\n\n\n Description of logic.<\/p>\n\n\n\n The code block\u2019s logic:<\/p>\n\n\n\n 2D geometry logic:<\/p>\n\n\n\n From these outputs, four parametric rectangles were created:<\/p>\n\n\n\n For the strip:<\/p>\n\n\n\n To get a 3D culvert:<\/p>\n\n\n\n To Explain identified good alternatives, and why they represent well embodied solutions, three representative alternatives were selected:<\/p>\n\n\n\n These illustrate how the parametric model can be used to trade off durability and structural robustness against material consumption and fabrication cost.<\/p>\n\n\n\n In a next step, the same Dynamo model could be extended to include a simplified flexural capacity check.
