However, a pier structure made by this method is required to secure strength.
A large number of main rebars, horizontal rebars, or assembled rebars must be placed in a congested state inside the hollow of the formwork block. I was In particular, a long-sized bridge has a disadvantage that it requires a lot of labor and a long time because the number of pier bases to be constructed is large, and the number of assembled reinforcing bars is accordingly large.

[0005] When a pier structure made of only reinforcing steel is subjected to an extremely large seismic force, there is a possibility that irreparably large residual displacement may be caused. On the other hand, an attempt is made to reduce such residual displacement. If this is the case, it will be necessary to take measures such as an increase in the cross section and an increase in the amount of steel material, resulting in uneconomical design.
