Published Papers

 
A prediction method for fatigue enhancement of drilled crack-arrest holes accompanied by splice plates
Takeshi Hanji, Shogo Kiyokawa, Kazuo Tateishi, Masaru Shimizu
Proceedings of the 12th Pacific Structural Steel Conference   CD-ROM   Nov 2019   [Refereed]
The present study examined a prediction method for the strain at drilled fatigue crack-arrest holes covered by splice plates to evaluate fatigue enhancement of the hole accompanied by the splices. Finite element analyses were performed in order to...
A study on fatigue crack propagation behavior on steel plate subjected to out of plane bending
Kentaro Horio, Kazuo Tateishi, Masaru Shimizu, Takeshi Hanji
Proceedings of the 12th Pacific Structural Steel Conference   CD-ROM   Nov 2019   [Refereed]
Under out-of-plane bending and shearing force, a crack develops in the thickness direction with an inclination toward the axial direction. Typically, three types of crack propagation behaviors can be observed; the crack develops in thickness direc...
Fatigue strength of single-sided fillet welded joints with low transformation temperature welding material
Suguru Kano, Takeshi Hanji, Kazuo Tateishi, Masaru Shimizu, Tadahisa Tsuyama, Toshio Takebuchi
Proceedings of the 12th Pacific Structural Steel Conference   CD-ROM   Nov 2019   [Refereed]
This study investigated the applicability of low transformation temperature (LTT) consumables to improve fatigue strength against weld root failure. Transverse attachment joints formed by single-sided welding, similar to rib-to-deck connections in...
Low cycle fatigue behavior of load-carrying cruciform welded joints with incomplete penetration
Yuko Ohashi, Takeshi Hanji, Kazuo Tateishi, Masaru Shimizu
Proceedings of the 12th Pacific Structural Steel Conference   CD-ROM   Nov 2019   [Refereed]
This study examined low cycle fatigue behavior of load-carrying cruciform welded joints containing incomplete penetration. Six types of specimens with different sizes of weld penetrations and weld leg lengths were tested under cyclic plastic strai...
Evaluation of low cycle fatigue crack propagation under various controlled cyclic loading histories
Arief Panjaitan, Kazuo Tateishi, Masaru Shimizu, Takeshi Hanji
Proceedings of the 12th Pacific Structural Steel Conference   CD-ROM   Nov 2019   [Refereed]
Low cycle fatigue, is one of the main failure modes in steel structures due to the earthquake. Earthquake acceleration leads to contribute irregular and high plastic deformation to the affected structures. However, the low cycle fatigue durability...

Fatigue life prediction of corroded reinforcing steel bars
Takeshi Hanji, Niamatullah Ahmadzai, Kazuo Tateishi, Masaru Shimizu
Journal of Constructional Steel   26 804-810   Nov 2018   [Refereed]
This study investigated the fatigue strength of corroded reinforcing steel bars. Several types of rebars consisting of different yield stress and rib shapes were used. The rebar was galvanically corroded to three levels, which are considered as a ...
Slip strength of doubler plates with high-strength bolts for fatigue cracks
Shogo Kiyokawa, Takeshi Hanji, Masaru Shimizu, Kazuo Tateishi
Journal of Constructional Steel   26 277-283   Nov 2018   [Refereed]
As for retrofitting cracked bridge members, it is often used to attach doubler plates by highstrength bolts after drilling holes at crack tips. In many cases, the doubler plate is designed as frictional connections, but the slip action at the doub...
Fatigue strength of cruciform joints with laser-arc hybrid welding
Takeshi Hanji, Kazuo Tateishi, Masaru Shimizu, Daisuke Uchida, Ryosuke Kimura, Koichi Asano
Quarterly Journal of the Japan Welding Society   36(4) 219-229   Oct 2018   [Refereed]
This study examined fatigue strength of cruciform joints fabricated with laser-arc hybrid welding. Load-carrying and non-load-carrying cruciform welded joints with a plate thickness from 8mm to 25mm were tested under tensile cyclic loads and out-o...
Fatigue cracks in I-beam end in railway steel bridges and its life extension by stop-hole repair
Takeshi Hanji, Kazuo Tateishi, Masaru Shimizu, Masaki Iwai, Ken Ikegashira, Yuichiro Niwa
Journal of Structural Mechanics and Earthquake Engineering, JSCE   74(2) 290-305   Aug 2018   [Refereed]
