Ukai
bridge (Nagara river, Gifu Prefecture)
■Bridge type: Single span hanging ■Bridge length：469m
DAINICHI has for many years been a high profile company in
the design of bridges extending their skills far beyond the
technical field, compositing beautiful landscape view of the
infrastructure studying topographical and regional characteristics.
Registered consulting engineers involve in the design of both
classical and state-of-the-art bridge structures. We are committed
to a management style that incorporates teamwork, efficiency,
integrity, and a sense of humor.
We maintain coordination of in-house expertise in hydraulic,
geotechnical, mechanical, and electrical engineering to supplement
its capability to design technically correct and functionally
sound structure. Our mission is to create a bridge harmonizing
the needs of people and the blessings of nature.
Computer aided design packages and latest graphical interface
computer programs are used for analysis and design. Particular
attention is giving to the seismic response analysis to improve
ductility of the structure in order to minimize the earthquake
damages. We use 3-dimensional finite element analysis to carry
out the dynmic analysis. DAINICHI also simultaneously pays
attention in the planning and repairing of the structures
for the assests management.
DAINICHI awarded the Tanaka prize 2003 from Japan Society
of Civil Engineers (JSCE).
