520			\|a This research explores the seismic performance of multi-segment columns, which are gaining attention due to their segmented prefabrication and assembly that address transportation and installation challenges. The main objective is to investigate the effective use of grouted sleeves as connections, both between column segments and to the foundation, in order to achieve satisfactory seismic behavior. To achieve this objective, an experimental program involving reversed cyclic tests was conducted on three precast specimens, which were compared to a reference conventional cast-in-place (CIP) column. The precast specimens featured grouted sleeve connections, with variations in the number of column segments and the connection types. The test results showed higher peak strength but reduced ductility in the grouted sleeve specimens compared to the CIP column. Moreover, multi-segment columns displayed significant improvements in ductility (12.8%), deformation capacity (27.0%), and energy dissipation (14.8%) compared to the single-segment column. Transferring grouted sleeves to the foundation further improved ductility by 18.0%. In parallel, a finite element (FE) modeling method was developed, with simplified representations of cushions and grouted sleeves. The FE results exhibited satisfactory agreement with the experimental findings, validating the accuracy of the developed FE models in terms of hysteresis curves, residual displacement, peak strength, and energy dissipation.

The main objective is to investigate the effective use of grouted sleeves as connections, both between column segments and to the foundation, in order to achieve satisfactory seismic behavior. To achieve this objective, an experimental program involving reversed cyclic tests was conducted on three precast specimens, which were compared to a reference conventional cast-in-place (CIP) column. The precast specimens featured grouted sleeve connections, with variations in the number of column segments and the connection types. The test results showed higher peak strength but reduced ductility in the grouted sleeve specimens compared to the CIP column. Moreover, multi-segment columns displayed significant improvements in ductility (12.8%), deformation capacity (27.0%), and energy dissipation (14.8%) compared to the single-segment column. Transferring grouted sleeves to the foundation further improved ductility by 18.0%. In parallel, a finite element (FE) modeling method was developed, with simplified representations of cushions and grouted sleeves. The FE results exhibited satisfactory agreement with the experimental findings, validating the accuracy of the developed FE models in terms of hysteresis curves, residual displacement, peak strength, and energy dissipation.

abstract	This research explores the seismic performance of multi-segment columns, which are gaining attention due to their segmented prefabrication and assembly that address transportation and installation challenges. The main objective is to investigate the effective use of grouted sleeves as connections, both between column segments and to the foundation, in order to achieve satisfactory seismic behavior. To achieve this objective, an experimental program involving reversed cyclic tests was conducted on three precast specimens, which were compared to a reference conventional cast-in-place (CIP) column. The precast specimens featured grouted sleeve connections, with variations in the number of column segments and the connection types. The test results showed higher peak strength but reduced ductility in the grouted sleeve specimens compared to the CIP column. Moreover, multi-segment columns displayed significant improvements in ductility (12.8%), deformation capacity (27.0%), and energy dissipation (14.8%) compared to the single-segment column. Transferring grouted sleeves to the foundation further improved ductility by 18.0%. In parallel, a finite element (FE) modeling method was developed, with simplified representations of cushions and grouted sleeves. The FE results exhibited satisfactory agreement with the experimental findings, validating the accuracy of the developed FE models in terms of hysteresis curves, residual displacement, peak strength, and energy dissipation.
