“…Local strengthening approaches, like cover plating, post-tensioning of beam elements via steel or CFRP, are generally more performing in all the other cases, they are more adopted and better known, demonstrated by literature case studies and workshops [1,5,[19][20], as well as interviews.…”

<p>Strengthening old bridges is an increasingly relevant strategy for risk prevention and operation continuity in management of infrastructures. Transportation networks are subjected to progressively stricter environmental and load conditions, leading to a growing number of deficient structures, also due to aging and deterioration. However, employable resources are finite, from both economical and environmental points of view. For these reasons, strengthening opportunities should be considered as a viable option, improving bridges behaviour with low economical and environmental impact. With this perspective, a selection of some of the most interesting strengthening techniques for old truss railway bridges is presented. To address effective solutions, the most frequent problems in old truss railway bridges are first presented. Literature analysis and experts’ interviews were conducted and compared to results obtained from a representative bridge cluster. Different solutions addressing highlighted problems are then collected and qualitatively evaluated, in terms of efficacy on structural behaviour and typical construction requirements. Finally, general remarks and recommendations based on collected evidence are presented.</p>

“…Because of that, preparing a reliable method as a practical tool for assessment of the conditions of existing bridges has become a very important research field [1,2]. Nowadays, many research teams are working on a non-destructive testing (NDT) of truss bridges in their works [3][4][5][6]. There are several available methods how to monitor structures or to check operational conditions of bridge structures.…”

Truss bridges are integral part of the transport network, mainly railroads and partially road bridges. The investigated bridge is located in the western part of Slovakia, and it crosses the Vah River. Density of traffic on the bridge is not so high, so the bridge is accessible for repeating dynamic measurements. Many load situations were simulated. Among of them also a case, where one diagonal member was excited by an electromagnetic exciter during the measurements and the influence on other diagonals have been also analyzed. Results of dynamic measurements are shown in this paper in comparison to analytical solution and to FEM calculations.

“…n the past years, the rehabilitation process of civil engineering structures such as bridges and overpasses has gained relevance [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. Several structures are reaching their design life in Europe and America, which leads the engineers to a new concern: the need to develop rehabilitation projects aiming to guarantee structural integrity and design life increase [15].…”

ABSTRACT. The Hercílio Luz suspension bridge, built in 1926, has been out of service since 1991 due to high corrosion levels and structural element impairment. A complete rehabilitation project was developed which included the replacement of the impaired items and foundation strengthening. For this, an auxiliary structure was employed to support the central span during the rehabilitation process. A carefully studied load transfer process, where the central span loading is transferred from the eye-bar towards the auxiliary structure will be performed. For this purpose, a synchronized jacking sequence will be used, which was predefined by means of numerical model analysis. All structural elements had their designs evaluated and some geometric changes were implemented. This paper presents all the methodology developed in the rehabilitation project of Hercilio Luz bridge, as well as the development stages up to the present date.
