STANDARD SPECIFICATIONS FOR CONCRETE …

2 The society can only preserve itself in wholesome with tough, beautiful and durable CONCRETE structures. CONCRETE Committee of Japan Society of Civil Engineers (JSCE), leading organization for investigation, research, technological promotion and education of CONCRETE in Japan, considers the issuance and revision of STANDARD SPECIFICATIONS for CONCRETE Structures as its most important activity. STANDARD SPECIFICATIONS for CONCRETE Structures (JSCE-SSCS), which show the model for plan, design, execution, maintenance and repair of CONCRETE structures, have been highly recognized in practice and contributed to the development of CONCRETE technology in Japan since its first publication as STANDARD SPECIFICATIONS for Reinforced CONCRETE 1931.

3 In order to cope with the development of CONCRETE technology in Japan and the worldwide trend, CONCRETE Committee converted all SPECIFICATIONS in JSCE-SSCS namely Structural Performance Verification , Seismic Performance Verification , Materials and Construction , Maintenance , Dam CONCRETE and Pavement , from the Prescriptive Code to Performance-based Code and completed the work in 2002. This revised edition adopts the technological development after 2002 and intends to enhance the performance-based nature in STANDARD SPECIFICATIONS .

4 For practical efficiency, the three SPECIFICATIONS - Design , Materials and Construction and Dam CONCRETE present not only general provisions for verification of specified performance requirements but also STANDARD methods as simplified methods to achieve the performance requirements under certain conditions. JSCE-SSCS is ready for practical use as it describes the role of each Specification during the plan, design, execution, maintenance and repair phases as well as the relationship among them. And for the first time, it also describes roles of engineers for construction works.

5 This JSCE-SSCS is yet an ultimate one. There are still remaining tasks, such as inclusion of provisions for scenario of CONCRETE structures during service life. What readers can find in this revised edition is rationality with the performance-based concept and the applicability for practice, showing the high level of technology in Japan. This revised JSCE-SSCS consists of five SPECIFICATIONS ; Design, which combines the previous Structural Performance Verification and Seismic Performance Verification together, Materials and Construction, Maintenance, Dam CONCRETE and Test Methods and SPECIFICATIONS .

6 Specification of Test Methods and SPECIFICATIONS was issued separately in May 2007. Specification of Pavement was published as STANDARD SPECIFICATIONS for Pavements 2007 by the Committee on Pavement Engineering of JSCE, which has taken over the issuance and revision works from JSCE-SSCS. Finally I would like to show my most sincere gratitude to Prof Taketo UOMOTO and Dr Tadayoshi ISHIBASHI, Chairman and Secretary General of Sub-committee on Revision of STANDARD SPECIFICATIONS for CONCRETE Structures as well as its Secretaries, Conveners and Members who devoted themselves continuously despite the tight drafting schedule.

7 My gratitude also goes to Advisors, Secretaries, Executive Members and Members of CONCRETE Committee, who reviewed the draft. December 2007 Toyoaki MIYAGAWA, Chairman CONCRETE Committee of Japan Society of Civil Engineers Preface to the English Version The Japan Society of Civil Engineers (JSCE) CONCRETE Committee has been publishing the STANDARD SPECIFICATIONS for CONCRETE Structures in Japanese since 1931. The English versions were published twice in 1987 and 2005 when the limit state design and the performance-based concept were introduced in the 1986 and 2002 editions of STANDARD SPECIFICATIONS for CONCRETE Structures (JSCE-SSCS) for the first time, respectively.

8 Since 2004 the CONCRETE Committee has put efforts to enhance information dissemination overseas by presenting various English publications including the series of JSCE Guidelines for CONCRETE . CONCRETE Committee has also decided to prepare the English version of every edition of JSCE-SSCS. This Sub-committee on English Version of STANDARD SPECIFICATIONS for CONCRETE Structures was established in 2008. Our task is to prepare the English version of four SPECIFICATIONS : Design, Materials and Construction, Maintenance and Dam CONCRETE of the 2007 edition of JSCE-SSCS.

9 Specification of Test Methods and SPECIFICATIONS of JSCE-SSCS is not included in this English version. However, some of these STANDARD test methods and SPECIFICATIONS have been translated for publication in a series of JSCE Guidelines for CONCRETE . Please visit the website of CONCRETE Committee at for the information on the English publications. This English version includes most of the contents in the original Japanese version. Utmost efforts have been made to ensure that the translation accurately convey the description in the original Japanese version.

10 If there were any discrepancy between the Japanese and English versions, however, reference should be made to the original Japanese version. Translation of technical work does not only require expertise but a lot of time and dedication. I am grateful to all the members for their tiring efforts. My heartfelt appreciations go to Prof YOKOTA Hiroshi (Secretary General), Dr SHIMOMURA Takumi (Head, WG for Design), Prof SUGIYAMA Takafumi (Head, WG for Materials and Construction), Dr MAEDA Toshiya (Head, WG for Maintenance), Prof AYANO Toshiki (Head, WG for Dam CONCRETE ) and Dr ISHIZUKA Takayuki who proof-read all the translated SPECIFICATIONS .
