@article{Kota Kono_Akihisa Nakahashi_Dong Daicho_Nobuo Fukushima_Ryoichi Fukagawa_2017, title={STRACTURAL SIMULATION ON AN OPEN-WING-TYPE GROUND ANCHOR}, volume={14}, url={https://geomatejournal.com/geomate/article/view/2883}, abstractNote={<p>The anchor method involves connecting a structure or a slope with the anchorage zone by<br>using the frictional force between the grouting material and the surrounding ground to stabilize the structure<br>or slope. However, over a long period of time said friction from traditional anchoring methods has been<br>known to decrease, resulting in decreased anchor pullout resistance and ultimately, in anchor pull out. An<br>open-wing type (OW) anchor method developed by our research group is a new type of earth anchor method,<br>in which we use open wings for pullout resistance. Hence, this method can solve problems associated with<br>existing methods. This study suggests an optimum structure for the parts that open in the OW anchor using a<br>numerical analysis, ANSYS (FEM). Three types of 3D analytical models – rotation axis type, bended steel<br>sheet type, and impaction type – are used. The analysis results show the optimum structure to be the<br>impaction type structure, and simulations show that with a base metal yield strength safety factor of 1.5, an<br>OW anchor could generate approximately 4250 N of extreme pullout resistance.<br><br></p>}, number={46}, journal={GEOMATE Journal}, author={Kota Kono and Akihisa Nakahashi and Dong Daicho and Nobuo Fukushima and Ryoichi Fukagawa}, year={2017}, month={Aug.}, pages={89–94} }
