“…It is assumed that the bias factor, λ, for the live load distribution factors specified in the design code is between 1.10 and 1.20, and that the coefficient of variation, V, is 0.18 (Barker and Puckett [37]). This study adopted a bias factor of 1.15 and a coefficient of variation of 0.18.…”

Steel bridges corrode due to environmental exposure. The consequence is a reduction in both the load-carrying capacity and safety of a bridge. Therefore, it is needed to evaluate procedures for an exact prediction of the load-carrying capacity and reliability of bridges, in order to make reasonable decisions about repair, rehabilitation and renewal. The aim of this study is to develop and demonstrate a procedure for the assessment of steel box girder bridge ultimate strength reliability that takes the degradation of plate members due to pit corrosion into account. The present paper treats the effect of pitting corrosion on the load-carrying capacity and reliability of steel box girder bridges and the results are compared with the uniform corrosion effect. The procedure and results of this study can be used for the better prediction of the service life of deteriorating steel box girder bridges and the development of optimal reliability-based maintenance strategies.

“…The grillage analogy is applied for modelling different types of bridge decks as a well establish and refined technique [2,[3][4][5][6][7][8][9][10][11]. While computing load distribution coefficients by the grillage the remaining analysis can be done with line beam analysis.…”

Abstract:The numerical method for computing the live load distribution coefficients in bridge decks is presented. The grillage analogy for representation of bridge decks is adopted in determining the general behavior under traffic loads. The principles of Maxwell's reciprocal theorem are developed in computing live load distribution coefficients and their influence lines. The presented method uses the approach developed in traditional methods of transversal live load distribution but bridge decks are modeled more realistic with the help of well-established grillage analogy. Simple numerical programs for grillage analysis can be used and no special software is needed. While computing the distribution coefficients for a bridge deck the rest of the analysis can be performed with habitual procedures of structural mechanics.

Tomando los puentes como ejemplo, se analiza la visión que de ellos tienen los propios ingenieros; a continuación se relacionan los principales parámetros que rigen su concepción y se evalúa la importancia de la componente paisajística del proyecto, advirtiéndose una divergencia de opiniones entre unos autores y otros. La existencia de cuatro vías de aproximación social hacia el elemento constructivo «puente» -descritas asimismo en el texto-demuestran tanto la fuerte presencia de éste en la cultura como su potencia en tanto que elemento paisajístico. El último apartado del texto sintetiza las conclusiones resultantes de la reflexión.Palabras clave: Puentes; paisaje; estética; ingeniería estructural; diseño conceptual; patrimonio. ABSTRACT
