Authorship：Lead author Language：Japanese Publishing type：Research paper (scientific journal)

This study proposed a simple method for estimating local stresses in as-welded
joints and established a fatigue assessment method by using the estimated local stress.
In this method, the local stress at the as-welded toe is estimated from the stress at the
weld toe finished by grinding, where the stress can be measured by strain gauges.
Fatigue tests and finite element analyses were conducted with out-of-plane gusset
welded joints in as-welded and finished conditions. Based on the results, the local
stress at the as-welded toe was correlated with the stress at the finished groove. It
was concluded that the fatigue strength of the as-welded joints can be evaluated by
using the local stress estimated by the proposed method.

Kazuo Tateishi, Takeshi Hanji, Naoki Nagamatsu

Journal of Constructional Steel, JSSC Vol. 19 page： 355-360 2011.11

Language：Japanese Publishing type：Research paper (scientific journal)

This study investigated the effect of extremely low cycle fatigue strength
improvements on steel bridge piers by weld toe grinding. Low cycle fatigue tests on
steel pier specimen of which base joints were finished by grinding were performed.Test
results revealed that the fatigue strength of the pier was improved by the toe grinding in comparison to those in as-welded condition. Local strains around flnished weld toe were analyzed by finite element analysis. It was confirmed that it is possible to estimate the extremely low cycle fatigue life by using local strain and suggested fatigue strength curves.

Retardation of fatigue crack propagation in welded joints under plate bending by hardening material injection Reviewed

Kazuo Tateishi,Ryuichi Tsuboi,Takeshi Hanji

Proc. of the 6th International Symposium on Steel Structures page： 352-357 2011.11

Authorship：Lead author Language：English

The number of fatigue cracks at in steel bridges is increasing, while it is difficult
to repair all cracks just after detecting them. In this study, a simple repair method for
cracks in steel bridges was proposed.This method can retard or arrest the crack
growth by injecting hardening material into the crack to restrain its closure. To verify
the applicability of the proposed method, fatigue tests under plate bending were
conducted on out-of-plane gusset welded joints repaired by the hardening material
injection. lt was indicated that effect of the crack growth retardation depends on
when injecting the hardening material into the crack, and that the proposed method can
extend the fatigue life regardless of the stress ratio.
