Introduction to English Version
Standards reflect the achievement of civilization, provide common languages for
technical communications and improve global connectivity. In recent years, the
Chinese government has been proactively implementing standardization to stimulate
innovation, coordination, greenness and opening up for shared development in
China and worldwide.
To align with the Belt One Road Initiative for mutual
development, the Ministry of Transport of the People’s Republic of China organized
the compilation and publication of international version of Chinese transportation
industry standards
and
specifications
to
meet
the
increasing
demands
for
international cooperation in transportation, enhance global connectivity, promote
knowledge dissemination and sharing of experience.
JTG is the designation referring to the standards and specifications of highway
transportation industry, issued by the Ministry of Transport of the People ’ s
Republic of China. This system emcompasses the entire lifecycle of highway
engineering projects, from planning and construction to maintenance and operation
management. It includes standards for the facilities, technologies, management,
and services required throughout these processes, as well as standards related to
safety, environmental protection, and economic evaluation.
In the highway standard system, it includes a number of standards for design,
construction and maintenance of bridges, which have effectively supported the rapid
development of highway bridges in China. The current bridge design specifications
include: General Specifications for Design of Highway Bridges and Culverts,
Specifications for Design of Highway Reinforced Concrete and Prestressed Concrete
Bridges and Culverts, Code for Design of Highway Masonry Bridges and Culverts,
Specifications for Design of Highway Cable-stayed Bridge, Specifications for Design of
Highway Suspension Bridge, Specifications for Design of Highway Concrete-filled
Steel Tubular Arch Bridges, Specifications for Design of Highway Precast Concrete
Bridges, Wind-resistant Design Specification for Highway Bridges, Specifications for
Collision Design of Highway Bridges, Specifications for Landscape Design of Highway

Bridges, etc. As of the end of 2022, 1. 033 million highway bridges with the total
length of 85. 765 million meters have been built in China, among which concrete
bridges accounts for more than 90% .
Specifications for Design of Highway
Reinforced Concrete and Prestressed Concrete Bridges and Culverts is one of the
fundamental standards for structural design of highway bridges and culverts, and has
been widely applied to the transportation industry of China.
The first edition of Specifications for Design of Highway Reinforced Concrete and
Prestressed Concrete Bridges and Culverts (JTJ 023-85) was issued in 1985 which
underwent the first revision in 2004 (JTG D62—2004) and the second revision in 2018
(JTG 3362—2018). After nearly 40 years of technical development, a complete
technical system for the design of highway concrete bridges and culverts has been
established. The Chinese version of Specifications for Design of Highway Reinforced
Concrete and Prestressed Concrete Bridges and Culverts (JTG 3362—2018) was revised
and issued in July 2018 and put into effect on November 1, 2018.
Specifications for Design of Highway Reinforced Concrete and Prestressed Concrete
Bridges and Culverts ( JTG 3362—2018 ) has adopted the limit state design
methodology, which is based on the probability theory and expressed with partial
factors. Technical requirements for overturning resistance design of box girder
iii
bridges, analysis models for spatial effects, design methods for disturbed regions,
design methods for bridges with external tendons and others were supplemented.
These developments have played an important role in promoting technical progress
in bridge construction and improving quality of highway concrete bridges.
The release of the English version of the Specifications aims to share the
engineering experience and technical achievements from China and provide
references for other countries to build highway bridges and culverts with similar
construction conditions.
The editing of the English version was conducted by Fuzhou University under the
authorization of the Ministry of Transport of the People’ s Republic of China and
approved by the Highway Department, the Ministry of Transport of the People’ s
Republic of China.
The contents and numbering of the chapters, sections, clauses and sub-clauses in
the English version are consistent with those in the Chinese version. In the event
of any ambiguity or discrepancy between the English version and the Chinese
version of the Specifications, the Chinese version shall prevail.
Gratitude is given here to Mr. Yuan Hong, the chief editor of the Chinese version,
for the valuable guidance and comments during the review of the English version.
Feedbacks are welcome and will be taken into account in future editions. Please
address them to the chief editing organization for English version in writing

The revision has been approved and issued as Specifications for Design of Highway
Reinforced Concrete and Prestressed Concrete Bridges and Culverts ( JTG 3362—
2018) for implementation.
During the revision, the editorial team conducted extensive special studies and
research works,
reviewed
the
updated
technical
development
and
design
experience in
China, and
referred
to
relevant
domestic
and
international
standards. Upon the completion of the first draft of the Specifications, the drafted
specification was circulated for comments from relevant experts and organizations
involved in design, construction, maintenance, and administration, based on
which several rounds of discussion, consultation, and updating were conducted
before being finalized for approval.
The main revisions made in this version include the following contents: strength
grades of reinforcement used in concrete bridges and culverts were updated; basic
requirements for the design of bridge structures were added; design requirements
for durability of concrete bridges and culverts were emphasized; requirements for
checking of overturning resistance of concrete box girder bridges, practical refined
analysis methods for complex bridges, design methods for bridges with external
tendons, and design methods for disturbed regions of concrete bridges were
supplemented; calculation methods for resistance on cross-sections of circular
compression members were updated; calculation formulas for determining effective
iv
length factors of compression members with different boundary conditions were
added; calculation methods for determining crack width in reinforced concrete
structures
or
Type
B
prestressed
concrete
structures
were
adjusted;
and
requirements for detailing design were supplemented.
Feedbacks are welcome and will be taken into account in future editions. Please
