Viaduct over River Almonte. Design and Analysis

Abstract

<p>The High Speed Railway (HSR) link Madrid - Extremadura crosses over River Almonte with a great arch viaduct of high - performance concrete. The main span of this structure is 384 meters.</p><p>This paper explains the exceptional techniques and structural analysis outside the usual engineering work that have been developed to reach its design and construction. These studies include the selection of the antifunicular arch axis taking into account construction process and train loads, geometric and material nonlinear analysis, dynamic analysis and aerolastic behaviour.</p>
