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 ...
Evaluation of the effects of recycled aggregates on the properties of high performance concrete
In recent decades, the use of High Performance Concrete (HPC) has grown vastly, being used in multiple applications with high requirements. However, the use of recycled aggregates (RA) has been mostly limited to conventional ...
Characterization and modelling of previous concrete
Pervious concrete is a special material with high permeability usually obtained by reducing the amount of fine aggregates in the composition of concrete. The properties of pervious concrete not only depend on its composition ...
Diseño de una nueva barrera continua de hormigón "in situ"
Pervious concrete is a special material with high permeability usually obtained by reducing the amount of fine aggregates in the composition of concrete. The properties of pervious concrete not only depend on its composition ...
Structural behaviour and design criteria of spatial arch bridges
Spatial Arch Bridges (SABs) are defined as bridges in which vertical deck loads produce bending moments and shear forces not contained in the arch plane due to their geometrical and structural configuration. Moreover, the ...
Structural design and characterisation of FRC precast segments
Concrete technology has changed greatly in the past decades. Steel fibre reinforced concrete (SFRC) is an example of the development in this field. It is obtained by adding fibres that act as a reinforcement of the cement ...
Sustainability concepts applied to the design of recycled aggregates concrete
Due to the related problems and the ongoing awareness on environmental issues is that efforts are put in different areas of knowledge, in order to determine, analyze and formulate solutions towards a sustainable future. ...
Comportamiento y diseño de hormigones estructurales con áridos siderúrgicos EAF
The use of the EAF steel slags as aggregate in the production of concrete has gained great interest with the increasing concern about the environment impact and the sustainability in the construction industry. The EAF steel ...
Características estructurales del hormigón con árido reciclado mixto reforzado con fibras
Despite the advance that has led the incorporation of Annex 15 in the Spanish EHE-08, the use of recycled aggregate concrete (RAC) is minimum in structural applications. This regulation limits the percentage of substitution ...
Experimental and numerical study of the structural effects of steel corrosion in continuous RC beams
Many reinforced concrete structures suffer damage due to aging and due to the environmental agressivity, thus affecting their serviceability performance and safety. Structural evaluation of a deteriorated structure is ...
Modelling and structural analysis of historical masonry systems including vaulted structure
The conservation of historic structures has been given special attention due to their cultural, social and economic importance. However they often show considerable structural vulnerability and have been seriously damaged ...
Los pináculos de la Sagrada Familia : restauración y obra nueva
Antoni Gaudí developed, for the pinnacles ofthe Sagrada Famí!ia, a unique constructive solution with precast concrete elements which were slightlyreinforced and covered with a trencadís ofMurano glass (Venice). In the ...
Derivation of the properties of masonry through micro-modeling techniques
The aim of this thesis is to present a framework for the application of micro-modeling techniques for the analysis of unreinforced masonry structures. Finite element analyses of case studies from the literature are carried ...
Sensitivity of urban buildings to tunneling-induced settlements
Tunneling construction represents an alteration to the distribution of soil pressures that will almost inevitably generate ground subsidence, which can endanger the adjacent buildings in urban areas. The risk of building ...
