Abstract:

There are two main objectives of this study. 1) Develop and validate two finite element models—one for small-scale specimens with single couplers, and another for half-scale columns. The small-scale model is validated against experimental results under lateral static and dynamic conditions, while the half-scale model is compared with experimental results under seismic loads. This involves calibrating material properties, mesh size sensitivity, and bond-slip laws to ensure accurate validation. 2) Using sequential and quasi-static cyclic loading protocols, assess the impact performance and residual seismic capacity of the calibrated half-scale columns following an impact event. This provides insight into the structural integrity and resilience of precast concrete columns with grouted splice sleeves (GSSs) under extreme loading conditions.
