Abstract:
As a result of a study, a multispan rigid frame was selected as the standard type for elevated bridges on the new 320-mile railroad connecting Tokyo and Osaka. This paper describes the preliminary design to select a standard frame, and the design and construction techniques used for the nearly 70 miles of bridges which incorporate the selected standard. Details are presented on torsional moments in double-tee beams; design of beams; problems concerning the slabs and columns; lateral stiffness and earthquake re-sistance; footings; and foundation settlement.
