History of IPA
Foundations/Structures play an important role in the recent civilization, however, the design is dependent on experienced bases.The interaction mechanism of piles/sheet piles and ground is important in the Press-in Method.
IPA was established in 2007 to aim to present a new framework, which gets rid of experienced bases, by researching the behavior of structures based on this feature.
|Jul. 1975||The first ‘reaction based’ hydraulic sheet pile jacking/pressing machine was developed
by Mr Akio Kitamura of GIKEN LTD. in Japan.
|Oct. 1990||The piling work by the Press-in Method was adopted for the Cambridge
Crystallographic Data Centre.
|Oct. 1994||The research collaboration started between GIKEN and the Cambridge University.|
|Oct. 2002||Prof. D. White, one of the current directors of IPA, earned a PhD degree related to the Press-in Method.|
|Sep. 2005||The IPA Preparatory Assembly was held at Kochi University of Technology
in Japan.(Founders : Mr Akio Kitamura of GIKEN LTD, Prof. Malcolm Bolton of the
Cambridge university and Prof. Hajime Okamura of Kochi University of Technology)
|Nov. 2006||The IPA Preparatory Committee invited cooperative research proposals.|
|Jan. 2007||The 1st IPA Research Grant Award winners were announced.|
|Feb. 2007||The IPA General Assembly and Inaugural Workshop were held at the Cambridge University. Then, Prof. Malcom Bolton assumed the post of
the first IPA President.
|Apr. 2016||Dr. Osamu Kusakabe assumed the second IPA President.|
