Preface The author stayed in West Germany for two and a half years and had a chance to participate in the design of some cable-stayed bridges at the Leonhardt Design Office. Here mainly introduces the information collected during the stay in West Germany, hoping to contribute to the development of Japanese concrete cable-stayed bridge. In the past, most of the main girders of concrete cable-stayed bridges were prestressed concrete, but some of them were reinforced concrete girders. In the future, all of them may also use reinforced concrete girders.
