Improving Pile-Body Performance for Major Earthquakes and Developing Short SC Piles
First written in FY2017. 2 of 5 entries say "Advanced", first in FY2020. Latest entry: FY2022.
2 other companies' latest entry also says "Advanced".
- FY2022AdvancedAnnual report
「Continuing from the previous consolidated fiscal year, we worked to develop pile bodies (HIT-TSPRC piles and HIT-TSPRC-ST piles) that reinforce the shear strength and axial load-bearing capacity required of precast concrete piles during earthquakes, and obtained an evaluation from the Japan Building Center.」
Regarding improved pile-body performance during major earthquakes, development of HIT-TSPRC piles and HIT-TSPRC-ST piles progressed through obtaining evaluations from the Japan Building Center. - FY2020AdvancedAnnual report
「Continuing from the previous consolidated fiscal year, we worked to develop pile bodies (HIT-WSC piles) that reinforce the performance required of precast concrete pile bodies under major-earthquake conditions, including deformation performance, axial-force retention and load-bearing capacity, and obtained an evaluation from the Japan Building Center.」
Development of HIT-WSC piles, which reinforce pile-body performance during major earthquakes, progressed through obtaining an evaluation from the Japan Building Center. - FY2019RestatedAnnual report
「We also continued from the previous consolidated fiscal year to develop pile bodies that reinforce the performance required of precast concrete pile bodies under major-earthquake conditions.」
The company continues to develop pile bodies that reinforce the performance required of precast concrete piles during major earthquakes. - FY2018ReframedAnnual report
「The performance required of precast concrete piles during major earthquakes includes flexural strength, shear strength and deformation performance. Accordingly, we continued from the previous consolidated fiscal year to develop new pile bodies focused on these characteristics.」
The focus on improving pile-body performance during major earthquakes continues, but the explanation now refers to developing new pile bodies rather than the previously described development and evaluation of short SC piles. - FY2017First statedAnnual report
「We continued our research and development efforts to improve the flexural strength, shear strength and deformation performance required of pile bodies during major earthquakes. As one way of addressing unevenness in the supporting ground, we developed short SC piles and obtained an evaluation from the Japan Building Center.」
The company identifies improving pile-body performance during major earthquakes as an R&D theme and has progressed with short SC piles through obtaining an evaluation from the Japan Building Center.
