German cable-stayed bridges 1955-1979Dischinger, Leonhardt, Holmberg, others.
How do innovations arise?Pressing social need (15,000 bridges destroyed in the war) and a system that ultimately proved economical for intermediate spans.
How are innovations related to the culture in which they arise?Truss bridges also would have worked (cheaper too!). Germans rejected old forms on aesthetic grounds, instead had an expressed desire for elegance (technic?) which led to experiments in new forms. Also, German design competitions led to innovation in systems
How did new technology influence the development?Structural analysis innovations allowed for new confidence, but new technology came primarily from construction desires: high strength wire, hydraulic jacking, cantilever construction to name a few.

Usually if we speak of cable-stayed bridge design parameters, we have their cable-arrangement, pylon-geometry, the cross-sections and the materials of their deck etc. in mind. But the overall layout is considered to be more or less invariable: a three-span arrangement with two pylons, a main-span and two holding down side-spans, and occasionally half of that with one pylon.

Usually if we speak of cable-stayed bridge design parameters, we have their cable-arrangement, pylon-geometry, the cross-sections and the materials of their deck etc. in mind. But the overall layout is considered to be more or less invariable: a three-span arrangement with two pylons, a main-span and two holding down side-spans, and occasionally half of that with one pylon.
However, the cable-stayed bridge concept offers more and can adapt to very special boundaryconditions…the outcome may be e.g. one out of a large number of feasible multi-span arrangements, or a combination of cable-stayed and cable-supported. Other situations may call for cable-stayedbridges, where the deck is not straight in plan but curved, or even for convertible or folding decks.
