Japan Society of Civil Engineers (JSCE) was established as an incorporated association in 1914 entrusted with the mission to contribute to the advancement of scientific culture by promoting the field of civil engineering and the expansion of civil engineering activities. Committee on Steel Structures of JSCE was reorganized in 1971 aiming to research and investigate steel materials, steel structures and composite structures, and to contribute to the progress of science and technology in a field of civil engineering. Since its establishment, the committee has organized a lot of subcommittees and they have produced a lot of outcomes related to steel materials, steel structures and their technological standards.
The internationalization of technological standards and the performance-based design are paid to attention in recent years. In the performance-based design, the improvement of transparency and ac- countability, the reductions of cost and negative environmental impact, and securing the quality and the performance, etc. are basic requirements. The committee resolved to make the ”Standard Specification for Steel and Composite Structures” including hot technologies in 2004 as the JSCE specification does not fall behind the world trends. The specifications consist of 6 volumes. ”General provision”, ”Basic Planning” and ”Design” were published in 2007, ”Seismic design” was issued in 2008, and ”Construction” was also come out in 2009 in Japanese. ”Maintenance” will be also appeared soon. These are the first standards by the committee on steel structures made as the performance-based design format and the limit state design method. I think that it is very meaningful to have completed the specifications using the performance-based design format at this time when a technological standard of western countries aims at the world standard.
It is expected that the contents of the specifications does not reveal only a state of the latest technology of the steel structure but also the direction of activities that the committee should aim. This English version was translated from the Japanese originals of ”General provision”, ”Basic Planning” and ”Design” of ”Standard Specification for Steel and Composite Structures”. I hope that the specifications will be useful and helpful for the design of steel and composite structures in the world.
Finally, warm acknowledgment is expressed to all of the members of the Sub-Committee on Standard Specification for Steel and Composite Structures and the Committee on Steel Structures for their efforts to preparation of the specifications and their invariable suggestions to the contents of the specifications.

In 1987, the Committee on Steel Structures published two design codes based on Allowable Stress Design Method. They are ”Design Code for Steel Structures PART-A: Structures in general” and ”Design Code for Steel Structures PART-B: Composite structures”. The newly revised above versions based on Limit State Design Method were published in 1997.
In 2000, the committee on Steel Structures organized a sub-committee for investigation of the performance-based design method. Its activity was to prepare and recommend a new design format, performance-based design for steel structures, coping with globalization. The report entitled ”Towards performance-based design method for steel structures” was published in 2003. The committee on Steel Structures has recognized that the basic design format for steel structures of the next generation was established. After the publication of the above report, the committee on Steel Structures organized the sub-committee on Standard Specifications for Steel and Composite Structures in 2004. Its role is not only to incorporate latest research fruits but to publish an innovative and competitive performance-based limit state design method for steel and steel-concrete composite structures of the next generation.
It consists of 6 volumes namely ”General provision”, ”Basic Planning”, ”Design”, ”Seismic design”, ”Construction” and ”Maintenance”. The three volumes including ”General provision”, ”Basic Planning” and ”Design”, were issued in 2007. It is based on the performance-based limit state design method, and is the first time publication for the design of steel and composite structures in civil steel structural engineering field in Japan. The volume of ”Design” deals with not only steel structures but also concrete slabs and steel-concrete composite girders for composite girder bridge design. Many of the provisions for steel structures are from those in ”Design Code for Steel Structures PART A: Structures in General” published in 1997. Even though we seldom design composite girder bridges in Japan, hybrid structures including composite girders have been recognized to be worldwide competitive alternatives. For global competition, the provision for composite girders is inevitable. In addition to introducing the design formulae by AASHTO LRFD or EC given in PART-B, the original formulae developed by Japanese young researchers were incorporated. This is also the first time action in Japan after the publication of PART-B in 1997. I hope the revising work continues towards global-top design of the next generation.
The preparation of an English version including three volumes started in 2007 by many of code writers on a voluntary basis. First of all, I would like to express my sincere gratitude to all writers for their devoted contribution. I also have to express my sincere gratitude to JSCE Research Fund, Committee on ISO Affairs in Civil Engineering, Prof. Yoda of Waseda University and Prof. Nogami of Tokyo Metropolitan University for their financial supports on publication of the English version. I would like to give my sincere thanks to all members of the committee on Steel Structures and of the sub-committee on Standard Specifications for Steel and Composite Structures for their valuable comments.
