This research is about design optimization and performance evaluation for composite PC slabs using improved horizontal shear connectors. As a result of the tests, the improved shear connectors show structural performance even when they are placed only in the required section.

This research is about the optimization of design and application of the horizontal shear connectors for composite PC slabs. As a result of test, the improved horizontal shear connector shows a structural performance that can displace the lattice horizontal shear connector.
