Abstract

We, Osaka office of Japan Railway Construction Public Corporation (JRCC), developed the RC rigid-frame elevated bridge (400m) that is perfectly continuous and is possible to apply to the every long span. Taking notice of the long rail track and being sure that theory were applicable to the rigid-frame viaduct, the design and execution were performed. And we tried again to mesure in various way for a year and have verified that basic theory. This paper reports the outline of design, execution, a part of the result of measurements and its consideration.
