Reinforcement Method for Bridge Piers with Embedded Reinforcement Bars "AT-P Method"

By significantly reducing the weight increase due to reinforcement, the burden on the foundation structure and the ground is alleviated!

The "AT-P method" is a seismic reinforcement method for bridge piers that minimizes the thickness of the reinforcement layer (minimum 34mm) compared to the RC wrapping method with external reinforcement and the conventional PCM wrapping method. The increase in thickness of the wrapping is reduced to about 1/8 of the RC wrapping method and less than 1/2 of the conventional PCM wrapping method, resulting in almost no increase in the riverbed obstruction rate for bridge pier reinforcement in rivers. Additionally, by directly embedding reinforcement bars into the existing concrete, it is possible to reliably improve load-bearing capacity without increasing the concrete cross-section. 【Features】 ■ The increase in wrapping thickness is reduced to about 1/8 of the RC wrapping method and less than 1/2 of the conventional PCM wrapping method. ■ The riverbed obstruction rate for bridge pier reinforcement in rivers hardly increases. ■ Load-bearing capacity can be reliably improved without increasing the concrete cross-section. ■ The burden on the foundation structure and the ground can be reduced. *For more details, please refer to the PDF document or feel free to contact us.
