In case of Enlargement method using Post-installed Anchors, mechanical expansion anchors were resisting tensile and shear force of Modular extension structure in exist building. The purpose of this study is to investigate cyclic load shear strength of Post-installed Anchor on 16 MPa low strength Concrete under less than standard effective depth(hef). The fracture pattern of the specimens in cyclic load shear tests was steel failure of anchor and the strength showed 19% less than that of the design strength on test anchor manufacturer.
