Connections between precast elements are fundamental to ensuring adequate structural performance, not only for current loading but also considering extreme events such as earthquakes and hurricanes. Thus, high-performance, low-cost and easy-to-apply connections will be developed and validated, supported by a comprehensive approach including experimental testing and numerical simulations. Full-scale tensile, shear, and out-of-plane tests will be carried out. Wall-to-wall, wall-to-foundation and wall-to-floors are some of the connections that will be studied. Detailed simulations will complement the testing campaign to optimize the solutions herein developed.
