Understanding how different parameters affect the dynamic response of high-speed railway bridges is crucial to selecting an efficient structural form. Despite existing numerous publications within this field, only few address the importance of torsional deformations. The main objective of this thesis is to investigate the influence of the torsional resistance of the deck on the dynamic response of an existing bridge. Ulla River Viaduct is presented as a case study, allowing to analyse some aspects of its design and what their alteration entails. To this end, 6 different 3D FE models are compared, 5 of which show a modification from the original configuration. In addition, several positions of the train are considered to contrast the effects when the torsional modes are excited. The performed dynamic calculations are based on the implicit direct integration procedure. The analysis of the case study demonstrates the benefit of closing the torsional circuit of the deck. The results also evidence the need of including torsional effects in its dynamic assessment when low values of torsional rigidity are considered. All this is not easy when simplified 2D or 3D beam models are used. As a final remark, the original design of the Ulla River Viaduct is found highly efficient from a dynamical point of view.

A method for occupational risk assessment in construction sites is developed in this study. This method provides a system to perform exhaustive analysis of the situations that could result in serious accidents. The main characteristic of this method is the integration of the safety and health legislation of three legal frameworks associated with the monitoring of construction procedures. The method is structured in three stages: protocol, data analysis system and risk control procedure. The protocol provides a systematic in situ evaluation, through requirements for identifying and assessing the gravity of the factors that can contribute to an accident. Likewise, it allows identifying the workers in areas of risk. The data analysis system is a tool that processes the information gathered in the protocol. The result is a set of quantitative indicators characterizing the work environment. A significant feature of this tool is its applicability to other productive activities besides construction. The main indicator provided by the method is the safety global index (Is). A formulation representative of the characteristics of the assessed environment and capable of effectively translating its safety level was developed. To this end, a classification range was defined based on the analysis of numerous risk assessments. A detailed study of the parameters of the formulation was conducted, testing their conceptual and mathematical consistency and the influence of one parameter in the others. The third stage of the method is the risk control procedure which establishes an action plan on the irregularities identified in the evaluation. The first version of this method was tested in six bridges and viaducts construction sites. When the necessary adjustments were identified, the effectiveness of the final version was verified twice in two construction sites, a bridge and a viaduct. The validation of the method was completed by means of a survey among the staff responsible for the prevention of accidents in the two construction sites and through the its verification according to a model of validation in operations research. In light of the above, conclusions from the theoretical basis of the method and the results obtained in the risk assessments performed in the construction sites of bridges and viaducts are drawn. / En este trabajo se ha desarrollado un método para la evaluación de riesgos laborales en obras de construcción. Éste método facilita un sistema de análisis exhaustivo de aquellas situaciones que puedan resultar en accidentes graves. Su principal característica es la integración de la legislación de prevención de riesgos laborales de tres marcos jurídicos, asociada al seguimiento de los métodos constructivos. Está estructurado en tres etapas: protocolo, sistema de análisis de datos y procedimiento de control de riesgos. El protocolo aporta una sistemática para la evaluación in situ, a través de requisitos para la identificación y valoración de la gravedad de los factores que puedan contribuir a un accidente. Igualmente permite la identificación de los trabajadores en las áreas de riesgos. El sistema de análisis de datos es una herramienta que procesa las informaciones originadas por el protocolo. Resulta en un conjunto de indicadores cuantitativos que caracteriza el ambiente laboral. Tiene como importante característica la aplicabilidad a otras actividades productivas además de a la construcción. El principal indicador facilitado por el método es el índice global de seguridad (Is). Se ha desarrollado una formulación representativa de las características del ambiente evaluado, que traduce muy eficazmente su nivel de seguridad. Para ello se ha desarrollado un rango de clasificación a partir del análisis de numerosas evaluaciones de riesgos. Se ha realizado un detallado estudio de los parámetros que componen la formulación, comprobando su coherencia conceptual y matemática, y la influencia de un parámetro sobre los demás. La tercera parte del método es un procedimiento de control de riesgos, que establece un plan de acción sobre las irregularidades identificadas en la evaluación. La primera versión del método fue testada en seis obras de construcción de puentes y viaductos. Identificados los ajustes necesarios, se verificó la eficacia de la versión definitiva con la aplicación por dos veces, en dos obras, un puente y un viaducto. Se ha concluido la validación del método a través de una encuesta realizada con los responsables de la prevención de accidentes de las dos obras, y a través de su comprobación respecto a los criterios propuestos por un modelo de validación de investigación operativa. De todo lo anterior, se han extraído conclusiones desde la fundamentación teórica del método, hasta los resultados obtenidos en evaluaciones de riesgos realizadas en obras de construcción de puentes y viaductos.

Im vorliegenden Beitrag werden die prognostizierten Verformungen gemäß der Materialmodelle des fib Model Code 2010 sowie der DIN EN 1992-1-1:2011 realen Messdaten gegenübergestellt, die über einen Zeitraum von mehr als 12 Jahren an einer großen Talbrücke erfasst wurden. Die numerischen Berechnungen zeigen, dass sich die Stoffgesetze deutlich in ihrer Höhe und dem zeitlichen Verlauf der prognostizierten viskosen Betonverformungen unterscheiden. Die höchste Übereinstimmung mit den Messdaten wiesen die Stoffgesetze des EC 2 auf.

The interest in structural health monitoring (SHM) has grown considerably in the past half century, due to an explosive growth in the availability of new sensors, the development of powerful data analysis techniques, and the increasing number of civil infrastructure that are approaching or exceeding their initial design life. In SHM, we acquire observation on the behavior of a structure to understand its condition state, based on which we decide how to manage it properly. However, this optimistic view of SHM is in contrast with what happen in real life: infrastructure operators are typically skeptical about the capacity of monitoring to support decisions, and instead of following the suggestions provided by SHM, they often act based on their experience or common sense. The reason is that at present it is not fully clear how in practice to make decisions based on monitoring observation. To fill this gap between theory and practice, I propose to consider SHM as a logical process of making decision based on observation consisting of two steps: judgment, in which the condition state of structures is inferred based on SHM data, and decision, in which the optimal action is identified based on a rational and economic principle. From this perspective, a monitoring system should provide information that can improe he managers knoledge on he srcral condiion sae enough to allow them to make better decision on the structure management. Therefore, in designing a monitoring system, the design target must be the accuracy in the knowledge of structural state achieved analyzing the observations provided by it. However, when an engineer designs a monitoring system, the approach is often heuristic, with performance evaluation based on experience or common sense rather than on quantitative analysis. For this reason, I propose a performance-based monitoring system design, which is a quantitative method for the calculation of the expected performance of a monitoring solution a pre-posteriori and for checking it effectiveness in the design phase. It is based on the calculation of the monitoring capacity and the monitoring demand the counterparts of structural capacity and demand in the semi-probabilistic structural design, and like in structural design, the solution is satisfactory if the capacity is equal or better than the demand. The choice in whether to invest a limited budget on a monitoring system or in a retrofit is another critical choice for infrastructure managers: a retrofit work can increase the capacity and the safety of a structure, while sensors do not change the capacity, nor reduce the loads. Recently, the SHM-community has acknowledged that the benefit of installing a monitoring system can be properly quantified using the concept of Value of Information (VoI). A typical assumption in the VoI estimation is that a single decision-maker is in charge for decisions on both the investment in SHM for a structure, and its management based on SHM data. However, this process is usually more complex in the real world, with more individuals involved in the decision chain. Therefore, I formalize a rational method for quantifying the conditional value of information when two different actors are involved in the decision chain: the manager, who operate the structure based on monitoring data; and the owner, who chooses whether to install the monitoring system or not, before having access to these data. The results are particularly interested, showing that under appropriate conditions, the owner may be willing to pay to prevent the manager to use the monitoring system. Application to case studies are presented for all the research contribution presented in this doctoral thesis.
