Tied-arch bridge (also called bowstring-arch or bowstring-girder bridge) is a type of bridge that has an arch rib on each side of the roadway (deck), and one tie beam on each arches, that support deck. Vertical ties connected to the arches support deck from above. It can be considered...
Tied-arch bridgeHangers or suspenders in cable-supported bridges are key load transfer components. These members are vulnerable to sudden fracture due to accidental damage, corrosion, fatigue, or during extreme events. Examples of collapse or damage in cable-supported bridges that are initiated by ...
Several examples of tied arch bridges are presented. The article presents also an example where the fatigue class of the detail regarding longitudinal stresses is evaluated thanks to a FE-modelization according to the 2008 IIW Fatigue Recommendations at the location of the attachment of a hanger. ...
Finally, the separated bending strain is utilized to estimate the deflection distribution of the tied-arch bridge through an improved conjugate beam method. Numerical and experimental examples are studied to illustrate the effectiveness of the proposed method for deflection estimation of tied-arch bridges...
characterized by the rational use of resources and by a formalization of the structural elements that make them modest examples of how structural engineering can serve, not only to fulfil a purely functional and resistant purpose, but also to contribute to ennobling the area in which a bridge is...
The assessment of the stability of concrete arch bridges is discussed through considering 4 heritage examples, which have no upper wind bracing. The relevance of this stability problem is due to the need of evaluating the load carrying capacity of older structures and also because of the increase...
The span length relation to arch height l/h =2,309 gives the minimum load bearing material amount. Practical examples are calculated numerically by using iteration, based on geometric vector algebra solution in finding the arch thrust line. The iteration is performed so that the weight of the ...
