Starting from an applicative problem related to the modeling of an element of a cable-stayed bridge, we compute the elasticity solution for a hollow cylinder loaded at the end faces with axial loads. We prove results of symmetry for the solution and we expand it in proper Fourier series; computing the Fourier coefficients in adapted power series, we provide the explicit solution. We consider an engineering case of study, applying the corresponding approximate formula and giving some estimates on the error committed with respect to the truncation of the series.

Starting from an applied problem related to the modeling of an element of a cable‐stayed bridge, we compute the elasticity solution for a hollow circular cylinder under axial end loads. We prove results of symmetry for the solution and we expand it in proper Fourier series; computing the Fourier coefficients in adapted power series, we provide the explicit solution. We consider an engineering case of study, applying the corresponding approximate formula and giving some estimates on the error committed with respect to the truncation of the series.

<p>This paper describes the structural design of the new Storstrøm Bridge under construction in Denmark, carried out by DMA - De Miranda Associati from the initial tender phase through development of basic design to the early phases of construction in 2021.</p><p>The bridge, the contracting entity for which is the Danish Road Directorate, is a prestressed concrete road and railway structure almost 4km long, including a central cable-stayed section with 160m spans and two approach viaducts.</p><p>The paper describes the design concepts, structural concepts, construction methods, static and dynamic analysis, as well as the wind analysis and the wind tunnel test campaign designed by DMA and carried out for assessing the structural response of the bridge to wind action.</p>
