Key Points

This work aims to analyze the bond behavior between post-installed and cast-in-place reinforcements to develop more efficient design concepts.
Examined single anchors and various joint arrangements in normal and steel fiber concrete.
Evaluated the load-bearing capacity and ductility of post-installed joints compared to cast-in-place joints.
Conducted experiments on (n)-to-(n-1) and 2:1 joint configurations.
Post-installed joints demonstrate superior bond stresses compared to cast-in-place joints.
The capacity of post-installed joints reaches or exceeds that of purely cast-in-place joints.
Steel fiber concrete enhances both load-bearing capacity and ductility.

Investigates bond behavior of post-installed and cast-in-place reinforcements in concrete, suggesting design improvements.
