Abstract:
This presentation will introduce the concept of Tessellated Structural-Architecture (TeSA) systems and will describe an experimental test of a reinforced concrete TeSA shear wall. TeSA systems are comprised of individual tiles arranged in tessellations or repeating geometric patterns. Tiles are topologically interlocking, which means that they transfer forces by nature of their geometry rather than through a bonding adhesive or mechanical connection. A benefit of such a system is the ability to rapidly disassemble the tessellation and repurpose the tiles. Additionally, there is a potential benefit of localizing failure and rapidly repairing individual damaged tiles, rather than the entire system. In this manner, TeSA structures are sustainable due to the reuse of materials and resilient due to the ability for rapid repair. The TeSA concept is demonstrated through a test program involving reverse cyclic loading of the specimen. General load-displacement behavior, crack propagation, and energy dissipation will be discussed for virgin and repaired TeSA walls.
