摘要：
Maintenance work for civil structures is essential to sustain their long lives. Some damage to steel member, such as thickness decreasing or perforating, brings deterioration of their ultimate strengths and shortening of their lifetime. However, a damage criterion for the steel member is still indistinct. Therefore, it becomes important how to evaluate residual strength of damaged members. This paper presents a buckling test and finite element analysis of perforated cylindrical tubular members, which are looked on as a damaged member, and characteristics of their ultimate strengths. Results of numerical analysis made influences of the perforation on the ultimate strength deterioration clear quantitatively.
