Cross-Sections of long Composite Bridges – Performance based Design

Abstract

<p>Steel-concrete composite bridges play an important role in building motorway bridges of small and of long spans. The paper puts the focus on large span bridges of the construction type deck bridge. Today, four different cross-sections are built regularly. These four cross-section types are investigated and the adequate area of use is proposed considering life cycle performance. Possibilities of further development are discussed.</p>
