Abstract: With existing RC buildings, in extreme cases, compressive strength is even less than 1/3 of design characteristic. No useful documents showing range of shear/pull-out loads for post-install anchors are available when anchoring at connections between new and existing concrete to retrofit such the buildings. From this background, planned research about anchoring with the object of seismic retrofit for low strength concrete buildings.
Defined, as low strength concrete is one whose compressive strength is 13.5MPa or less as per seismic diagnosis guideline. Used, as test parameters are compressive strength, anchor rod diameter/embedment, and edge distance. Tested group shear and single shear/pull-out. Also, from tests this time, shear and pull-out strength equations of post-install bonded anchors used for low strength concrete were proposed. These equations, on seismic reinforcement of low strength concrete buildings, concerning design of post-install bonded anchors, useful equations were proposed.
