抄録

For the renovation of the reinforced concrete boxed-wall building, a new opening would be constructed on multi-story wall frame, and local retrofit with post-installed adhesive anchors would be applied. In this study, evaluation method of tensile strength for a post-installed adhesive anchor embedded in wall plane was proposed. The non-fixed bond-tensile test of anchor specimens embedded in wall-slab specimen was conducted. The parameter of specimens are embedment length of anchors, wall thickness, and wall shapes. Tensile strength of the anchors could be evaluated due to previous formula with the assumption of the effect of local retrofit on bottom floor wall and floor slab.
