This report explains the contents of the draft of the revision for seismic design regulations which will be enforced in the near future. These are that the objective design criteria of the current law and the revision draft are not differrent so much from each other, and that secondary design prosedure which is mainly discussion on bearing horizontal capacity is proposed as a new regulation.
Further, several items related to calculation method for bearing capacity and to method to decide structural deformation ability which are appointed out as problems of the draft are explained stressing on reinfored concrete construction.

This paper describes the design and construction of the substructure of a 12-span continuous bridge in the length of about 510 meter. Reverse pile with large caliber was used for foundation and RC bent of H-type used for the pier. Both of them are worked by the use of D51 of large caliber iron bar as main bar. The pile was designed to have flexibility to the direction of the bridge axis. To maintain the flexible function a preventive work for closed displacement of the pier, was performed. To present the beauty of the RC pier, the pointed joint was made vertical, so that the pier appears slender.
