Abstract
Sugahara-Shirokita Oh-hashi, which is located at the northern part of OSAKA CITY, is 26.5m wide and nearly 1.4km length across YODO RIVER. The type of this main bridge is a single plane cable-stayed bridge with a central span of 238m and two side spans of 119m each. This paper gives an outline of design and construction for the cable-stayed bridge.
The main futures of this bridge are as follows:
(1) The bridge is not supported by the piers at its ends but is supported by the prestressed concrete bridge.
(2) Considering aesthetic design and aerodynamic stability, the slitted section was chosen for the pylon.
(3) Firstly, a central span is constructed by a staging method, secondly, the side spans are constructed by a cantilever erection method.
