Resumé

This manuscript presents the experimental investigations on the seismic behavior of precast grouted sleeve column-to-foundation connections. Six full-scale specimens were constructed with varying longitudinal reinforcement ratios and stirrup ratios. Four specimens were precast with grouted sleeve connections. Two cast-in-place reference specimens were equivalent in design with the precast ones, but only without the grouted sleeve connections.
Vertical compression ratio of approximately 0.41 was applied for use in high seismic regions. Damage states, load-carrying capacity, ductility, energy dissipation and strain distributions of the specimens are investigated and are compared with the cast-in-place reference specimens. The test results demonstrate that the sleeve connection exhibited comparable lateral deformation capacity and ductility but lower strength capacity compared to the
cast-in-place reference specimens. Among the precast specimens, the increase in stirrup ratio slightly increased both the yield and the ultimate strength. The increase in longitudinal reinforcement ratio showed greater effects by considerably raising the ultimate strength, while increasing the yield strength marginally.

Six full-scale specimens were constructed with varying longitudinal reinforcement ratios and stirrup ratios. Four specimens were precast with grouted sleeve connections.
