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. ...
Monitorización de estructuras de hormigón mediante sensores de fibra óptica distribuida
This doctoral thesis presents the use of an opto-electronic system so-called OBR (Optical Backscattered Reflectometer) as an alternative of measurement in structural health monitoring (SHM) processes in concrete structures, ...
Accelerated cementitious matrices : hydration, microstructure and mechanical strength
Sprayed concrete is widely used as structural support for the stabilization of tunnel walls and underground constructions. The performance of sprayed cementitious matrices containing accelerators is strongly related to ...
Sistema predictivo multiescala de la degradación del frente urbano edificado
Evidence from progressive deterioration of the urban building stock is well known. This brings about a large social and economic impact due to maintenance costs and associated personal hazards. This thesis explores ways ...
A direct performance based seismic design method for irregular structures : applications to concrete structures
El diseño de estructuras para satisfacer niveles prestacionales, o de desempeño específico ha ganado interés en la ingeniería sismo resistente. Actualmente, existen varias metodologías de diseño sísmico basadas en prestaciones, ...
Sustainability in the post-disaster temporary housing management for urban areas
Many people lose their homes every year due to natural disasters. One of the major challenges to mollify displaced persons is the provision of adequate post-disaster accommodations, temporary housing (TH) being the most ...
New approach for efficient design of stainless steel RHS and SHS elements
This thesis investigates the cross-section and member behaviour of cold-formed stainless steel RHS and SHS elements and proposes an alternative and more efficient design approach. Combined with aesthetic appeal, exceptional ...
Daylight performance assessment of an innovative energy efficient building envelope
Buildings are considered to be one of the primary contributors to the socioeconomic development of a country. However, they use a large portion of energy and available natural resources. With the industrialization leading ...
