Topology Optimization Based Additive Construction

The goal of this project is to optimize structural forms using topology optimization and sustainable
materials to reduce materials wastage and reduce emissions.

Specific Objectives:

• Develop concrete mixes without cement (either geopolymer or polymer concrete) and
  adjusting these mixes for additive construction and topology optimization
• Develop numerical modeling for optimized structural elements,
• Additively Construct Optimized structural elements
• Conduct Experimental Testing the Optimized Structural Forms Constructed through Additive
  Construction

Project Description: 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 (3D printing) provides unique opportunities to build form-free
structural elements and can enable topology and structural optimization.
