Fiber element models of 1-D interlocking TeSA wall

This project introduced a new modular reinforced concrete shear wall system designed for replaceability and resilience after extreme loading as well as architectural appeal. The walls are called tessellated structural-architectural (TeSA) walls because they consist of interlocking tiles (modules) with repetitive shapes (tessellations) and are intended to satisfy both structural and architectural demands. Tiles of TeSA systems can be interlocking in one or two directions, and can incorporate self-centering post-tensioning. This data set includes: (1) Continuum element models of 1-D and 2-D interlocking reinforced concrete TeSA walls. The models were created using a commercial finite element software (Abaqus). Walls with 1-D interlocking tiles had self-centering strands. Load-displacement and strand force-displacement (when applicable) data are presented for static pushover analyses. Wall design details are provided for the walls analyzed. (2) Fiber element model of a 1-D interlocking TeSA wall with self-centering strands. The model was created using OpenSees. Load-displacement and strand force-displacement data are presented for static pushover analyses. Wall design details are also provided. (3) Fragility functions for two 1-D interlocking TeSA walls with varying tile patterns. The functions were created using the fiber element models described above, captured uncertainties in applied axial loading, tile-interface properties, concrete compressive strength, modeling approach, and used lateral drift as the demand parameter. Design details of the walls, for which fragility functions were generated, are also provided.
