プレストレストコンクリート工学会

Message from President Shimomura
The Japan Prestressed Concrete Institute (JPCI) is the only academic organization related to prestressed
concrete (PC) in Japan, and was founded in 1958 as the Japan Prestressed Concrete Engineering
Association. Today, many infrastructures such as bridges, buildings, and tanks and so on are constructedusing PC structures, and PC structures and related technologies have become indispensable to modernsociety.
JPCI aims to contribute to the safety, security and development of society through the advancement ofscience and technology related to PC structures and their dissemination. To achieve this goal, we are doing
various activities which are publication of the journal "Prestressed Concrete", publication of books such as
various technical standards and guidelines, holding annual PC symposiums and various seminars, andcertification of engineer qualifications of "Prestressed Concrete Engineer" and "Concrete Structure
Diagnostician".
Along with the Japan Concrete Institute (JCI), JPCI is also a Japanese
official member organization of fib (The International Federation for StructuralConcrete), an international academic society on concrete structure, and isconducting the systematic international exchanges on the technology and theacademics of PC and concrete structure.
We are committed to addressing the important issues surrounding modernPC, such as preparation for large-scale natural disasters, maintenance andmanagement of existing structures, and response to decarbonization. We arealso committed to communicating the appeal of PC to the general public,
especially to the next generation, including students, in order to pass on PC
technology, enhance its presence, and promote its sustainable development.
We would appreciate your support and cooperation.
Dr. Takumi Shimomura, the 36th President of the Japan Prestressed Concrete Institute■JOURNAL of Prestressed Concrete
JPCI publishes bimonthly journal. The journal isrecognized as a valuable paper in the ﬁeld of structuralconcrete. It gives the latest and useful information ofprestressed concrete and structural concrete.

JPCEA (Japan Prestressed Concrete Engineering
Association) which is the forerunner of JPCI has beenfounded in 1958 to extend prestressed concrete
engineering in Japan and contributed over 60 years inprestressed concrete engineering and structural concrete.
JPCI co-organizes the national organization of fib (TheInternational Federation for Structural Concrete) with JCI(Japan Concrete Institute). JPCI mainly contributes toactivities of national organization in the ﬁeld of structuralconcrete. The oﬃcer of JPCI becomes a member of thefib presidium as a Japanese representative, participates inplanning and administrating of events.

■OUTLINE of ACTIVITIESJPCI was established for the veriﬁcation, advancementand promotion of prestressed concrete engineering. Ourmain activities are as follows.
(1) Research and promotion of prestressed concrete
engineering, and spread of those results(2) Publication of journals and reports, and providing
technical courses and lectures(3) Activities related with domestic and internationalorganizations(4) Qualiﬁcation and education for prestressed concrete
engineers(5) Various activities to attain our objects and publicinterest■COMMITTEE ACTIVITIESJPCI organizes working committees to carry out various
activities functionally. The following list is a part ofworking committees.
■ Technical Standard Committee■ Journal Editorial Committee■ International Committee■ Committee on Prestressing Reinforcements■ Symposium Organizing Committee■ Committee on Certiﬁcation of Authorized PrestressedConcrete Engineer■ Committee on Certiﬁcation of Professional Engineerfor Concrete Structural Diagnosis and Maintenance■ Committee on Selection of Public Oﬀering Research■ Committee on Archives of Prestressed Concrete
Technology

Repair & Strengthening of Existing Bonded
Post-Tensioned Concrete Bridges■ Report of Prestressed Concrete Structures on theGreat East Japan Earthquake Disaster■ Anchoring Device for Prestressed Concrete (2010)■SYMPOSIUM
JPCI holds annual symposium on prestressed concreteand structural concrete for advancement of prestressedconcrete engineering. Lots of technical papers andtechnical reports are presented.

■PUBLICATIONSJPCI publishes various books on
the prestressed concreteengineering. The following arepart of publications in Englishand Japanese.
JPCI and JCI jointly publish“National Report of Japan on
Prestressed Concrete Structures”
for International fib Congress.
“Prestressed Concrete forBeginners” is widely used for
education for college students and young engineers. The
Korean edition is also available.

technologies. The awards were founded in 1972 andwere given for the ﬁrst time in 1973. The award is one of
the most prestigious
awards in the ﬁeld ofprestressed concrete
engineering andstructural concrete inJapan.

■ENGINEER QUALIFICATIONS(1) Authorized Prestressed Concrete Engineer
JPCI certiﬁes Authorized Prestressed Concrete Engineer
to secure the quality of prestressed concrete structuresand improve the technical ability of engineers concernedwith prestressed concrete engineering. It is widely
recognized and required as the qualiﬁcation ofprestressed concrete structure construction for publicworks. As of April of 2023, more than 4,700 engineers areregistered as Authorized Prestressed Concrete Engineer.
(2) Professional Engineer for Concrete Structural
Diagnosis and Maintenance
The load of maintenance of structures has been
increasing along with the stock of infrastructure. In suchcircumstances, JPCI has established the program for theProfessional Engineer for Concrete Structural Diagnosis
and Maintenance program that certiﬁes the engineers
with wide and advanced knowledge for diagnosis andmaintenance of concrete structures. The wide activities
by Professional Engineers for Concrete Structural
Diagnosis and Maintenance are highly expected for the
maintenance of concrete structures.
