A simple structure that is strong against earthquakes and achieves performance that does not damage piles or foundation beams!
The "Captain Pile Method (CTP Method)" is a construction method that allows designers to adjust the connection state (fixity) between cast-in-place concrete piles and the foundation. Since the stress generated at the pile head during an earthquake is reduced, damage to the pile material can be minimized. The shear force from the superstructure during an earthquake is transmitted to the pile through a PC ring, and by placing tension anchoring bars, it can also accommodate the pulling force that occurs in the pile. 【Features】 ■ Improved seismic resistance ■ Rationalization of the foundation ■ Enhanced constructability and quality ■ Applicable to all building uses and structural types ■ Applicable pile types are cast-in-place concrete piles (pile diameter 800φ to 3000φ) *For more details, please refer to the PDF materials or feel free to contact us.

basic information
【Other Features】 - By using semi-rigid connections for piles and foundations, the bending moments of piles and foundation beams during earthquakes can be reduced, minimizing damage. - The reduction of bending moments at the pile heads allows for a decrease in pile diameter, reduction of foundation beam size, and a decrease in excavation volume, leading to cost reduction and shortened construction periods. - Since there are no pile anchoring bars during pile head treatment, it becomes easier to chip the pile heads, avoiding damage to the rebar. - The pile head joint is a simple design that only requires the installation of a PC ring, improving constructability and quality. - This method can be used by companies outside the association with permission from the association. *For more details, please refer to the PDF document or feel free to contact us.*
