We construct so-called "Optimized Bridges", which are modified to improve sustainability and incorporate ideas of economic design, in order to advance social infrastructure and longevity. The following characteristics are found in this category of bridge:
|
|
|
|
| 1 |
To improve the durability of RC slabs, which is the main area of damage
on bridges, PC slabs, pre-cast PC slabs and composite slabs are employed. |
| 2 |
To achieve economic design, girder types such as "open box girder",
"narrow box girder", "optimized steel deck I girder"
and "optimized truss" are applied. |
| 3 |
To achieve shorter construction periods and improve quality whilst working
in difficult erection environments, various innovative erection methods
are used. |
| 4 |
To reduce maintenance, we improve slab water proofing, employ new anti-erosion
steel and zinc aluminum sprays, and use function divided bearings. |
| 5 |
We use various methods of "high speed erection" to reduce time
on site as much as possible, in order to minimize disruptions to traffic
and city life. |
| 6 |
We employ new materials, such as "Stable Yield Point Steel",
"TMCP Steel", "Taper Steel Plate", "New weathering
Steel" and "Titan Cladding Steel". |

IHI , with its abundant experience and engineering manpower, strives to
develop advanced technology. IHI's target is to maintain control over the
bridges throughout their lifetime, and so the optimization of bridges,
taking into account life cycle cost, is becoming increasingly important
for us.
