Abstract
Wind speed in urban areas can create an unpleasant and dangerous environment, known as wind funnel effect, resulting in the non-use of urban spaces. This paper investigates a simulation-based method for designing tensegrity systems to mitigate the wind funnel effect in urban canyons, focusing on form finding of tensegrity systems. The following methodology was proposed: (1) modeling tensegrity structures accurately using Genetic Algorithms (GA) to find the most effective cubic units of struts and cables; (2) re-creating the wind funnel effect in a passage located between two parallel buildings; (3) finding the characteristics of the most porous windbreak structure that could effectively solve the funnel effect in the passage with the use of GA for optimization; (4) using tensegrity units acquired from step 1 to construct a windbreak with the characteristics found in step 3. All steps employed Fast Fluid Dynamic (FFD) simulations to test wind behavior in each environment. After this thorough investigation, the final results from the above steps showed that a proper combination of tensegrity units determined in step 1 is able to address the wind funnel effect effectively, creating a windbreak in a passage between parallel buildings.
