Abstrakt:

In this report, we report on the technological development in which we utilize an existing RC rigid- frame viaduct.

We plan to shift about 3.5km of a service route on the Senseki Line that was damaged by the tsunami of The Tohoku-pacific Ocean Earthquake. We will utilize the existing RC rigid-frame viaduct at the bridge approach. Therefore, we will plan to cut the existing viaduct and raise slab aspect height. However, in the cross-section of the existing columns, it has been found that aseismic performance is insufficient. Therefore, we developed a structure with a widened cross-section by deploy reinforcement steel materials in the other periphery of the columns.
