Influence of axial compression ratio in building columns
(English) Axial forces in columns of moment-resisting frames (MRF) have a paramount role for the seismic performance of these structural systems. Nonetheless, there are significant gaps in the literature entailing the ...
WIM-based modelling of traffic load scenarios for extreme load effects in long-span bridges
(English) During the lifetime of long-span bridges, the traffic conditions are affected by the surroundings and will typically vary and also unpredictably change. In this thesis, a prior site-specific traffic load spatial ...
Closing loops in intensive livestock systems: innovative strategies for nutrient recycling and emissions reduction
(English) The exponential growth of world population is leading to a high demand of food products and, consequently, to the development of intensive agricultural and livestock systems. In this sense, synthetic fertilizers ...
Understanding size-resolved dust emission from field measurements in Morocco
(English) Atmospheric mineral dust is composed of a variety of mineral particles exhibiting distinct composition, shape, and size. The wide range of diameters exhibited by dust particles, spanning more than three orders ...
Structural behaviour and plastic design of carbon and stainless steel frames in fire
(English) This thesis investigates the response of carbon and stainless steel frames in fire, and proposes new and more efficient approaches for their design. The investigation is mainly focused on one bay frames comprised ...
Activación alcalina de residuos urbanos e industriales para la construcción de piezas prefabricadas
(English) A comprehensive evaluation of various industrial and urban by-products was conducted to determine their potential as precursors for alkali-activated materials (AAM) in Spain. Over 15 by-products were identified ...
Modeling of container throughput in the European port system-analysis of container liner shipping networks
(English) This thesis records the evolution of the container throughput dynamics of the European port system from 2001-2020, analyses the dynamics of the European container port hierarchy with methodologies that have not ...
Real-time solutions of parametric thermo-hydro-mechanical problems with proper generalized decomposition
(English) The Proper Generalized Decomposition (PGD) is a mathematical framework belonging to the Model Order Reduction (MOR) class of techniques. To the best of the author's knowledge, this methodology has not been applied ...
On the evaluation of mixing in heterogeneous porous media: from laboratory characterization to the design of engineered chaotic flows for practical application
(English) Groundwater is now under high stress levels and its quality and quantity arise as one of the most interesting and necessary topics our community should address. This doctoral thesis is focused on the quality of ...
Structural performance of continuous composite bridges with partial shear connection and double composite action
(English) The steel-concrete composite structural solution has been widely applied in the execution of simply supported bridges since the merits of concrete compressive strength and steel tensile strength can be efficiently ...
Experimental and numerical analysis of the unsaturated soil shrinkage and swelling behaviour under different compaction conditions
(English) The thesis presents part of an ongoing nvestigation on the Thermo-Hydro-Mechanical (THM) behaviour and cracking of deformable unsaturated soils undergoing cycles of drying and wetting. An experimental approach ...
Determinación del grado de daño de una estructura mediante el análisis de la variación de frecuencias
(English) This thesis proposes to determine a damaged structure using the Principal Component Analysis (PCA) of modal frequency variation of sorne damaged and undamaged configurations. The estimators used are the accumulated ...
Study of hybrid FRP-FRCM superficial structural elements
(English) The most common composite materials for strengthening building structures are divided into two dif ferent types based on the matrix’s composition, organics (polymers) or inorganics (cement, lime). The hybrid ...
Soil-structure interaction in the performance-based seismic design of reinforced-concrete buildings
(English) When analyzing structures for seismic design and performance assessment purposes, it has been common to assume that the ground motions or their equivalent representations correspond to that of the free-field ...
Structural behaviour of stainless steel frames. Safety against accidental seismic actions
(English) Stainless steel is one of the most promising construction materials due to its long service life, low maintenance requirements, excellent mechanical properties and high residual value. Nevertheless, for an efficient ...
Estudio teórico y experimental sobre el comportamiento no lineal de estructuras continuas parcialmente pretensadas
(English) Performance-based design (PBD) is a philosophy for structural design that puts emphasis on the realistic estimation of the structural behaviour and its relationship with the objectives of the final user, or ...
Energy and material circularity in building-integrated agriculture : an environmental approach
(English) Cities are great resource consumers and largely contribute to anthropogenic environmental impacts, urgently requiring a decarbonization plan. Urban agriculture lies on industrial ecology principles; waste resources ...
Population dynamics, interactions and evolution of marine microbes using genomic approaches
(English) There is a myriad of microorganisms on Earth contributing to global biogeochemical cycles. In the surface ocean, the smallest microbes (picoplankton) are responsible for an important fraction of the total atmospheric ...
Visco-plasticity of zero-thickness interfaces with softening, and application to the study of fault reactivation
(English) In the current context of both energy and environmental needs, there has been an increase in activities related to extraction and injection of fluids in the underground. It is known that a possible consequence ...
Citizen sciences technologies for operational monitoring of aquatic ecosystems
(English) Light attenuation is a critical factor in aquatic ecosystems for many physical and biological processes. Water transparency plays an essential role in understanding the variations of the ecological environment ...
