鉄骨筋交いの既存鉄筋コンクリート構造への接着接合による耐震補強工法の研究(建築学科,工学部創設40周年記念号)

Abstract

The strengthening construction method where steel braces are joined to existing reinforced concrete frames by post installed anchor bolts, is often used in seismic strengthening of school buildings. But this method can not be executed while the classroom near the site is using because of its noise, vibration, and concrete dust. We have made shear experiment of joints between a steel member and a RC member those are joined with glue, and have made analysis whether these adhesive joints can be applied to the strengthening construction method, from the results of shear experiments with RC specimens of about 1/2.5 scale model. From those results, it became clear that the transfer mechanism of horizontal force from the RC frame to the steel brace in both the surface joint type and the inserted joint type, and also it was found that these adhesive joint is sufficiently applicable to the strengthening construction method by some improvement of longitudinal steel frames.
