“…As shown in [19], all eigenfrequencies calculated by solid finite elements agree very well with results obtained by experimental measurements. Other very recent aspects in the area of numerical solutions of non-uniform torsion are treated in [20]- [24]. Finally, in [2], a boundary element solution is developed for dynamic analysis, considering warping of beams with arbitrary cross-sections, including shear lag effects due to both flexure and torsion.…”

In this paper, the influence of the variable axial force and of the Secondary Torsion-Moment Deformation-Effect (STMDE) on the deformations of beams due to torsional warping is investigated. The investigation is based on the second-order torsional warping theory of doubly symmetric beams with thin-walled open or closed cross-sections. The effect of the axial force on the torsional stiffness of thinwalled beams is considered according to the second-order torsional warping theory. The solutions of the underlying differential equations are used for setting up the relations, needed for application of the transfer matrix method. They are derived, considering both static and dynamic action. This enables stablishing the local

“…The analysis of the beam is carried out in a classical way with the typical methods of calculation for beams with thinwalled sections that take into account the warping-torsion, the warping-distortion and the frame effect of cross sections, calculating the transverse moments in the webs and deriving the corresponding stresses associated with the tangential shear and torsional stresses. Here the longitudinal and transverse analyses are carried out following the HSA (Hamiltonian Structural Analysis) method (Arici and Granata, 2016) but it is possible to carry out a classical Saint-Venant analysis adding the transverse frame effect and cross section distortion through the well-known BEF (Beam on Elastic Foundation) Analogy. The sandwich method is successively implemented in the simplified form proposed in the previous sections, using the interaction domains with stress field inclination modification (Recupero et al, 2017) and taking out the reinforcements.…”

In concrete box girders, the amount and distribution of reinforcements in the webs have to be estimated considering the local effects due to eccentric external loads and cross-sectional distortion and not only the global effect due to the resultant forces of a longitudinal analysis: shear, torsion and bending. This work presents an analytical model that allows designers to take into account the interaction of all these effects, global and local, for the determination of the reinforcements. The model is based on the theory of stress fields and it has been compared to a 3D finite element analysis, in order to validate the interaction domains. The results show how the proposed analytical model allows an easy and reliable reinforcement evaluation, in agreement with a more refined 3D analysis but with a reduced computational burden.
