Abstract

<p>In the present contribution the development of an innovative structural system for short span roadbridges is presented. In particular, the use of prestressed concrete tension ties is shown to offer new possibilities for the conception and design of bridge structures. Aesthetics as well as structural efficiency are discussed. Transparency and structural simplicity are characteristics that contribute to a clear appearance. The reduction of dead load while maintaining sufficient stiffness is a general optimization task in structural engineering; it is shown that by choosing suitable dimensions and materials and an appropriate level of prestress convincing solutions can be achieved.</p>
