Integrated monitoring and structural analysis strategies for the study of large historical construction : application to Mallorca cathedral
Historical structures are vital to the realization of how the technical, artistic, and scientific skills of the human kind have developed over time. These structures are one of the motors of the tourism industry, and ...
Monitorització de projectes no determinats utilitzant Scrum i la Concept-Knowledge Theory
Planning and monitoring of projects are fundamental activities for its management. These tasks provide the required information to have a full picture of a given situation. They are an instrument that enables the control ...
Web crippling and local buckling response of stainless steel sections
This thesis examines the response of stainless steel members when subjected to transverse and normal forces triggering the instability phenomena called web crippling and local buckling, respectively. Currently, the part ...
MetodologÍa para la evaluación y seguimiento de procedimientos constructivos de forma sostenible e integrada
This doctoral thesis defines a new methodology for evaluating and comparing different construction projects in an objective and systematic manner. It is innovative by incorporating issues as diverse as cost, occupational ...
Gestión integral de obras hidráulicas de hormigón : del diagnóstico a la inversión
This doctoral thesis addresses jointly two paramount aspects in the management of the hydraulic structures in operating regime: the damage diagnosis and the investment prioritisation that should allow repairing such damages. ...
Escala de gravedad de daños en edificios : de la asignación directa a la contrastación estadística
To make the inspection and diagnosis of buildings is useful be able to quantify how far the existing deficiencies are serious or not, in order to facilitate the decision making and prioritize therapeutic interventions. In ...
Structural behaviour of tapered steel plate girders subjected to shear
Tapered plate girders often form part of large-scale structures such as long continuous bridges or industrial buildings where due to considerable loads the higher resistance is required. There are several important reasons ...
Bioreceptivity optimisation of concrete substratum to stimulate biological colonisation
The lack of green areas in cities is caused by the increase in population and the urbanisation process. However, an increasing interest in city greenery was observed since the beginning of twentieth century. Several benefits ...
Construction control of cable-stayed bridges
This work presents a study of the simulation of cable-stayed bridges built on temporary supports focused on their response during construction and in service. To simulate the behavior during construction, a set of four ...
Mezclas ternarias de cemento Portland, cemento de aluminato de calcio y sulfato cálcico : mecanismos de expansión
Portland cement is the most widely used building material. Is mainly composed of silicates, also has lesser proportion of aluminates and calcium sulfate. Its hydraulic nature generates in its hydration, the formation of ...
Bi-layer diaphragm walls : experimental and numerical analysis
Leakage is a widespread problem associated with the construction of diaphragm walls whenever they are erected in water-bearing ground. The aim of the present research is to develop a new type of slurry wall: the bi-layer ...
Contributions to rework prevention in construction projects
Literature usually suggests that construction organization can reduce the costs derived from rework implementing quality management systems. Most common challenges and obstacles that construction organizations face during ...
Characterization and control of wet-mix sprayed concrete with accelerators
The development of the wet-mix system and the use of the sprayed concrete as a part of the new Austrian tunnelling method (NATM) marked an increase in the use and in the structural responsibility of the material, with ...
Optimización térmica y energética de la doble fachada acristalada con ventilación mecánica en clima mediterráneo
El diseño de edificios siguiendo criterios de sostenibilidad y eficiencia energética se ha convertido en un imperativo en los países desarrollados, sobre todo a raíz de la Directiva europea 2010/31/UE sobre Eficiencia ...
Resistencia a cortante de los forjados de vigueta pretensada y bovedilla
A pesar de que los forjados de vigueta pretensada y bovedilla se han utilizado desde los años 40 en prácticamente todo el mundo, los modelos que actualmente se utilizan para su cálculo frente al Estado Límite Último de ...
Nuevo proceso constructivo de viaductos con cimbra autolanzable y nueva secuencia evolutiva
Durante los últimos años se han venido realizando viaductos con cimbra autolanzable y una nueva secuencia evolutiva de la sección transversal. Esta nueva secuencia evolutiva consiste en alcanzar un esquema autoportante que ...
Estudio del efecto de la nauraleza del árido reciclado en la microestructura y propiedades de la zona de transición árido-pasta de cemento.
Hoy día está ampliamente reconocido que la estructura de la matriz de cemento en las proximidades de los áridos, es distinta a la del resto de la pasta, aunque dicha microestructura de la zona interfacial es variable en ...
Efectos de los esfuerzos cortantes biaxiales en la respuesta sísmica de columnas de hormigón armado
Durante un terremoto, las columnas de hormigón armado pueden verse sometidas a movimientos bidireccionales que pueden afectar su capacidad resistente y ductilidad. Sin embargo, las normas de diseño y evaluación sísmica no ...
Interacciones microorganismo-hormigón: métodos de evaluación y posibles soluciones
La interacción microorganismo–hormigón es un proceso que, debido a la naturaleza porosa del hormigón, lo hace susceptible de ser colonizado por los microorganismos presentes en prácticamente todos los hábitats. Esta ...
A model for the nonlinear, time-dependent and strengthening analysis of shear critical frame concrete structures
Nonlinear fibre beam models, due to its intrinsic simplicity and computational efficiency, are often an adequate alternative to the complex nonlinear plane and solid FE models for the assessment of entire frame structures. ...
