000010918 520__ $$2eng$$aA main reason for early tensile brittle fracture of the anchor-bolts in the steel exposed-type column bases under the past earthquake is that the thread part has the decreased sectional area of 75% of the regular part of the anchor-bolt. Many existing old steel structures in Japan might contain such anchor-bolts whose deformation capacity is very poor and urgent diagnosis and upgrading is needed. This study proposes the method of upgrading the performance of anchor-bolts in existing old steel structures. A high-strength bolt equivalent to F14T is screwed to reinforce the thread part, after the hole is emptied from the top of the anchor bolt. This paper shows the performance of the upgraded anchor-bolts through the experimental studies.
