Seismic Performance of Cementitious Grout Filled Coupler and Sleeve Connections in Precast Wall Panels under Cyclic Lateral Loading

This study investigated the seismic performance of cementitious grout filled coupler and sleeve connections in precast wall panels under cyclic lateral loading. The effectiveness these enhancing concrete walls was evaluated. In many countries, grouted are preferred option, whereas were more commonly utilized India due to belief that a greater portion dowel being enhances structural stability. Tests conducted on full scale behaviour by applying displacement-controlled loading results discussed. experimental revealed connection exhibited better recommended for panel over connection. Compared connection, specimen with an unbonded segment demonstrated 8% rise energy dissipation, while displayed 55 % increase.
