In this board, as obtaining effects of strengthening and rehabilitating about the existing structures, it has objects to using a basic data which compared with effects of before the amount of reinforced concrete structure which are rehabilitated with carbon Sheets and after.
In aspect of strengthening, 12% is strengthening with rehabilitation with carbon sheets and this means that bridge with capacity in DB-18 state is strengthened to DB-20 states.
For additional effects, it may be reduced the corrosion of concrete and reinforced bar and also reduced flexural cracks, and it makes the increasing of serviceability as decreasing the deflections to 10∼20%.
as a results, which the increment of self-weight is very lower, effect of rehabilitation is extremely. so for the future use, it is expected widely to rehabilitate and strengthen the existing R/C structures.
