Generally, a curved bridge is designed and constructed as one of three types: (a) straight girders with a curved deck, (b) straight girders and decks used to set up a curved configuration, and (c) curved steel box girders with a curved deck.
For the performance of evaporations without curved configuration, the proposed model can give good calculations with the experimental data.
After the casting of the girder and the removal of the formwork, the girder is lifted and moved using a lifting device specially designed to prevent the over-turning from occurring due to the curved configuration.
The steel box-girder bridge type is widely used in the construction of curved bridges, because a curved configuration is easily attainable.
The study proposes new relationships between speed differential parameters for different visibility condition and geometries of tangent-curve configurations and increases the actual knowledge of driver's speed choices and driving behaviour under nighttime conditions.
The research was carried out using a driving simulator where a section of 10 km of an existing two-lane rural road composed by 39 tangent-curve configurations was implemented.
Nonlinear forced vibration of a viscoelastic pipe conveying fluid around the curved equilibrium configuration resulting from the supercritical flow speed is investigated with the emphasis on dynamics of external and internal resonance.
The method allows cracks with a general curvature and is not restricted to slightly curved crack configurations.
Five illustrative examples are presented and discussed, and the results displayed, namely load-deflection curves, deformed configurations and stress contours, are validated through the comparison with values provided by shell finite element analyses.
Points representing landmark configurations were then projected into Euclidean tangent space approximating the curved shape space.
