[2115] PRELIMINARY PUSH-OUT TEST AND FE ANALYSIS OF PERFORATED SHEAR CONNECTORS FOR REUSABLE STRUCTURAL ELEMENTS
Keywords:precast construction、reusable structure、shear connector、push-out test、numerical analysis
Aiming for suitable joints of reusable structural elements, the strength of perforated steel plates used as shear connectors welded to beam top flange and connected to concrete slab is investigated experimentally and numerically. Two types of joints were compared: Shear connectors when embedded directly in a concrete slab and shear connectors embedded in grouted pockets made in the slab. Test results showed the suitability of the latter type in terms of strength, deformation, ductility and stiffness.The numerical investigation proved to be appropriate in evaluating the behavior of such connectors.
