The bridge described here having a great deal of advantages as an elevated bridge, it appears before the footlights in the advanced nations of the world as well as Japan.
When the span of a reinforced concrete slab bridge becomes over ten meters in length, the dead load acting on the supports increases and a T-Beam or a Box Girder bridge has been adopted for the R.C.slab bridge.
Therefore, the simple circular hole bridge(Spanlength = 10~20M) is proposed in order to close the gaps.
The author discuss a method of an approximate solution instead of difficult calculations in this structure.
