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 ...
Shaping transport infrastructure in Sub-Saharan Africa (1884-2020). The impact of decision-making on network efficiency and sustainability: the case of Cameroon
(English) The objective of this research is to delve into the decision-making processes that shape the provision of transport infrastructure. To this end, it analyses the historical evolution of transport networks in ...
Environmental impact accounting of organic agricultural production systems: advancing inventory and biodiversity modelling approaches in life cycle assessment
(English) Agriculture not only contributes to more than a quarter of all global greenhouse gas emissions but is also the number one anthropogenic source of nitrogen emissions and a danger to nearly half of threatened ...
Mechanical characterisation of masonry in existing structures by means of laboratory and in-situ experimental techniques
(English) Masonry structures are among the most abundant construction typologies in the world, having been commonly built until the second half of the 20th century. The determination of the mechanical properties of these ...
Methodology for seismic vulnerability assessment of existing masonry buildings in urban centres. Application to the Eixample district in Barcelona
(English) Unreinforced masonry buildings (URM), which prevail in many historic and urban centres, can be considered to be significantly vulnerable to seismic actions due to their peculiar constructive and structural features ...
THM coupled behaviour of a deep poorly indurated argillaceous formation
(English) Deep geological disposal of heat-emitting and long-lived radioactive waste is the solution internationally accepted that offers the most viable and safest way to manage this kind of wastes. Accordingly, the ...
Dinámicas socioecológicas de la producción de durazno bajo el sistema de agricultura familiar periurbana en El Jarillo, Venezuela
(English) The Jarillo, Venezuelan Mirandina parish, has had an intense agricultural development since the end of the 19th century, the peach occupies one of its main crops since the middle of the last century. They are ...
Coupling shallow water models with three-dimensional models for the study of fluid-structure interaction problems using the particle finite element method
(English) This thesis investigates numerical methods for the simulation of surface water flows, focusing on the interaction between the large scale and the local scale and its application to natural hazards. Several families ...
Development of low-cost sensors for structural health monitoring applications
(English) There is increasing interest in developing low-cost sensors for economical structural health monitoring of civil engineering infrastructures. In addition to their price, they have the additional benefit of being ...
Conformal n-dimensional bisection for local refinement of unstructured simplicial meshes
[English] In n-dimensional adaptive applications, conformal simplicial meshes must be lo cally modified. One systematic local modification is to bisect the prescribed simplices while surrounding simplices are bisected ...
