Modern Structural Engineering Practice.



In the past, Structural Engineers developed structural concepts through trial and error, verified using multiple computer analytical runs, or perhaps just based on pure intuition alone that we fondly referred to as "engineering judgment". The results are often incomplete if not incompatible to the original architectural design intents and become more of design constraints as opposed to being complementary to the architectural design. Structural constraints compromise the Architect's creativity and limit the architectural design possibilities and aspirations. "Ai-Alt" not only address this issue but rather incorporate an entire new process into structural conceptualization, the process we call "Transtructuration."



What is Transtructuration?



"Transtructuration" is not just a term we coined but rather a form of computational design. It is an Ai-driven alternate structural design technique consisting of representing the architectural form in a given digital platform (e.g. Rhinoceros, Revit, Autocad 3D) by the structural element of the other (e.g. Revit, Dynamo, SAP2000, ETABS, etc.). The use of a set of algorithms define the compatibility between the architectural forms and the structural shapes using the "Transtructuration Standards" developed by "Ai-Alt" based in the team's almost three decades of structural design experience. These standards set the "Transtructuration Rules": which forms are replaced by which others, and in which case.





What is Transtructuration Used For?



The main goal of transtructuration operation in our design of the structure is to enable the unambiguous recreation of the original architectural design into an assemblage of structural elements which allow us to provide timely feedbacks to the project team regarding the viable structural option(s) in terms of construction type, structural member sizes, constructability and potential cost.



Case Study



Recreational Glass Slide (Confidential Project)



The project involved the conceptual study on the installation of a recreational glass slide, 830-ft above ground on the outside of one of New York City's iconic buildings. The glass slide will be installed within a continuous tubular "slinky" shape steel frame with main longitudinal tube sections (ribs) attached at each end to the existing building's main roof framing. To deal with the complexity of the geometrical 'slinky" shape frame, the analytical modeling were carried out using "transtructurated model" directly from architect's Rhinoceros model. The transtructuration operation ensures that the analytical model is a perfect match of the architectural design form and the result of the finite element analysis represents the true behavior of the structure as required for the architectural design intent.
