A STUDY ON BRIDGE DESIGN BY OSAKA MUNICIPAL ELECTRIC RAILWAY PROJECT IN OSAKA CITY BEFORE WORLD WAR II

Abstract

 This study aims to clarify the thought and the characteristics of bridge design developed by Osaka Municipal Electric Railway Project in Osaka City before World War II. The results are as follows; 1) There might be some ideas to unify the structural type and the construction cost of bridges for each railway route. 2) There are three main characteristics of bridge design from perspectives of architectural design and urban design; one is the unification of structural type and handrail design in bridges on the same route, another is the variety of handrail design in bridges on the specific route, and the other is the limited adoption of arch bridges, which were considered in the geological conditions and the importance of locations where bridges were built.
