Abstract:
For decades, concrete structures are constructed using cementitious based materials using conventional methods through formworks (either cast-in-place or precast). Concrete with sufficient slump is needed to fill up the formworks. This approach results in significant material wastage (where the material is placed at areas with low to very low stresses) and increases carbon footprint. Additive construction provides unique opportunities to build form-free structural elements with complex geometry which enable topology and structural optimization. This presentation include 1) Development of 3D-printed versions of concrete with lower carbon footprint; 2) utilization of advanced modelling techniques for topology and structural optimization of structural elements; 3) utilization of strut-and-tie methods for topology and structural optimization, and 4) small scale and large scale additive construction for optimized structural beam. The presentation will conclude with detailed comparison between conventionally constructed beam and additively constructed beam in terms of materials saving and emission reduction.
