Abstract: A conductive layered product includes: a transparent substrate; a first metal oxide layer; a metal layer; and a second metal oxide layer. The first metal oxide layer, the metal layer, and the second layer are layered directly or indirectly on a surface of the transparent substrate in this order from a transparent substrate side. An arithmetic mean roughness of an interface of the first metal oxide layer on the transparent substrate side is 2.0 nm or less. The interface of the first metal oxide layer on the transparent substrate side preferably contacts the surface of the transparent substrate. The conductive layered product preferably further includes a resin layer between the transparent substrate and the first metal oxide layer, and the interface of the first metal oxide layer on the transparent substrate side contacts a surface of the resin layer.

Abstract: A bridge pier structure includes a damper having damping characteristics, a substructure joined with a lower end portion of the damper, and a pillar member provided upright on the substructure, a side surface of the pillar member being joined with an upper end portion of the damper. The damper is substantially parallel to the side surface of the pillar member.

Abstract: A repair and strengthening system for a reinforced concrete structure has a ribbed steel plate, and a filler. The ribbed steel plate is disposed facing a strengthened area with a predetermined space therebetween. The strengthened area is an area to be strengthened in a structure surface that is a surface of a reinforced concrete structure. The filler is injected in the space between the structure surface and the ribbed steel plate. Ribs are formed on the ribbed steel plate by hot rolling. The ribs protrude from a steel-plate front face that is a side of the ribbed steel plate facing the structure surface.
