Lean construction versus Project Management in road projects : scheduling comparison
Lean Construction is regarded as an innovative approach of management for various types of projects in the field of construction. As much as it is currently applied in some countries, its expansion is inevitable, for better ...
Station keeping analysis and design for new floating offshore wind turbines
In the framework of the reduction of the emissions of greenhouse gases, FOWT will be the technology that will exploit the wind resources in deep seas. In order to achieve a commercial deployment of this technology, a cost ...
Geometrically non-linear analysis with stiffness reduction for the in-plane stability design of stainless steel frames
In AISC 360-16, the Direct Analysis Method (DM) has been set as the primary method for the stability design of frames. DM, considering initial global sway imperfection, is essentially Geometrically Non-linear Analysis (GNA) ...
Theoretical and experimental study of the behaviour at service and failure of partially prestressed concrete beams under flexure and shear
Partially Prestressed Concrete (PPC) is an intermediate design approach between reinforced and totally prestressed concrete, that enables controlled cracks in service phase. Conversely, totally prestressed concrete is ...
Intercalation mechanism of polycarboxylate-based superplasticizers into montmorillonite clays
The presence of clays in the sands used for concrete production interferes with the development of the fluidity of concrete, producing an instantaneous slump loss just after batching and the premature loss of fluidity. ...
Development of optical fibre distributed sensing for the structural health monitoring of bridges and large scale structures
In this doctoral thesis it is proposed to research and assess the performance of the use of distributed optical fiber sensors (DOFS), more specifically the case of the optical backscattered reflectometry (OBR) based system, ...
Enhancing building performance : a Bayesian network model to support facility management
The performance of existing buildings is receiving increased concern due to the need to renovate the aging building stock and provide better quality of life for end users. The conservation state of buildings and the indoor ...
Reacciones expansivas internas : estudio de los áridos y hormigón de presas
A significant part of the pathologies found in concrete dams is related with the presence of unsound aggregates that react with the cement paste. Such reactions may lead to expansions, causing damage and compromising the ...
Optimization of design procedures and quality control for FRC
Fibre reinforced concrete (FRC) presents objectively proven advantages in terms of post-cracking strength and manufacturing procedures. As a result, FRC with structural responsibility is increasingly being used in the ...
Optimización de la reología de componentes fotocatalíticos para aplicaciones avanzadas en elementos de fachada
This thesis discusses the development of a new methodology for 3D printing of TiO2 nanoparticles and its applications in air purification and hydrogen production. A dosage has been obtained that allows 3D printing by DIW ...
Assessment of chloride corrosion in steel fibre reinforced cementitious composites
High performance steel fibre reinforced cementitious composites (HPSFRCCs) show enhanced structural performance and durability. The improved properties favour its use in agressive conditions (such as marine environment) ...
Aportaciones al proyecto, construcción y reparación de pavimentos de hormigón
The construction and conservation of road networks represent a major part of public expenditure. For instance, the EU-28 countries annually spend approximately EUR 20.000 million on roadway preservation. These figures ...
Static structural system identification using observability method
During the construction and operation stages of structures, various factors lead to irreversible degradation that could affect the normal use and the public safety of these structures. In recent years, it has been common ...
Refuerzo a cortante de estructuras de hormigón armado con laminados de polímeros reforzados con fibras (FRP) : verificación experimental.
The use of externally bonded fibre reinforced polymers, FRP, for strengthening reinforced concrete (RC) beams or columns is an alternative to other traditional strengthening techniques due to its high strength-to-weight ...
Desarrollo de materiales con retracción compensada a partir del óxido de calcio (CaO)
The shrinkage of concrete and the current methods to mitigate this phenomenon are mainly based on the realization of retraction joints approximately 24 hours after the mixing. These joints represent a critical point in the ...
Evaluación de mezclas proyectadas : comportamiento y durabilidad
Sprayed cementitious materials are widely used in the construction industry, from buildings to infrastructure. The process of construction consists of spraying a concrete mix that consolidates once it reaches the substrate. ...
Tracking localized cracks in the computational analysis of masonry structures
Numerical methods aid significantly the engineering efforts towards the conservation of existing masonry structures and the design of new ones. Among them, macro-mechanical finite element methods based on the smeared crack ...
A system for crack pattern detection, characterization and diagnosis in concrete structures by means of image processing and machine learning techniques
A system that attempts to find cracks in a RGB picture of a concrete beam, measure the cracks angles and widths; and classify crack patterns in 3 pathologies has been designed and implemented in the MATLAB programming ...
New insights on the fundamentals and modeling of the external sulfate attack in concrete structures
The external sulfate attack (ESA) is a complex degradation process typically compromising the durability of underground foundations, nuclear or industrial waste containments and tunnel linings exposed to sulfate solutions. ...
Development of a coupled finite element model for early age concrete behavior : application to concrete pavements
Nowadays, concrete pavements are one of the main traditional options of building roads and highways. Moreover, concrete pavements are used for various ground transport infrastructures such as sidewalks, streets and airport. ...
