High structural performance can be achieved by a combination of improved material properties, innovative structural details and systems. Case studies of the following steel bridges in innovation aspects are examined: (1) A double Warren deck truss type highway bridge using cold-formed 750x750x23 mm hollow section as the lower chord members. Application of high strength weathering steel in the cold region of -25 C; (2) A 4-span continuous Shinkansen railway bridge with boat shaped box girder bridge under construction. Application of new weathering steel for obtaining a protective rust layer in a relatively short period in a severe coastal region of rough seas; (3) A laterally swing floating double arch bridge with a 280 m-span will be supported by the tow steel pontoons of 58x58x8 m after completion in 2000. The pontoons are covered with a 2,4 m width x 1 mm thickness titanium clad steel sheets for corrosion protection in a splash and tidal zone; (4) A reconstructed 19-span continuous rigid frame bridge with seismic isolators at the column bases in Kobe after the 1995 Kobe Earthquake.
