Quirós Collazos, Lucía (Data de defensa: 2022-06-27)
The present PhD thesis is focused on the paleoclimatic reconstruction of the Pacific Ocean equatorial upwelling conditions, east of the Galapagos Islands, over the last 160.000 years. This region is of great interest to ...
Duarte Gómez, Noemí (Data de defensa: 2023-05-12)
(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 ...
Herrera Mesén, Carlos Manuel (Data de defensa: 2018-03-16)
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. ...
Jiménez Pacheco, Juan Carlos (Data de defensa: 2016-12-16)
Currently, there are very few programs specialized in seismic analysis of unreinforced masonry buildings. Most studies have focused on the seismic behavior of the walls or (in a 3D level) have not integrated the flexibility ...
Rodríguez Rey, Daniel (Data de defensa: 2022-03-21)
Persistent high levels of NO2 have severe health effects on population. These are often found in large urban conurbations with high vehicle densities. In Barcelona, with one of the highest vehicle densities in Europe, the ...
Gonzàlez Corominas, Andreu (Data de defensa: 2016-06-21)
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 ...
Najdi, Abdallah (Data de defensa: 2023-06-20)
(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 ...
Gasparini, Andrea (Data de defensa: 2021-03-04)
CO2 geological storage is considered one of the options technologically viable in order to decrease the industrial emissions of this gas species that strongly contribute to the greenhouse effect in the atmosphere (IPCC, ...
Liaudat, Joaquín (Data de defensa: 2018-06-15)
This thesis aims at deepening in the understanding of the mechanisms by which the stress state affects the development of concrete expansions and cracking due to the Alkali-Silica Reaction (ASR). With this purpose, a ...
Fraccica, Alessandro (Data de defensa: 2019-12-09)
The thesis is aimed at characterising the multi-scale and hydro-mechanical behaviour of lightly compacted silty sand penetrated by a turf-grass (Cynodon Dactilon). The study will allow better assessing the impact of ...
Santín Muriel, Andreu (Data de defensa: 2022-01-24)
Sponge assemblages dominate several distinctive, hard-bottom environments, being one of the most important structural organisms at several locations around the world. Although the Mediterranean sponge fauna is among the ...
Gürkan, Ceren (Data de defensa: 2018-11-22)
This thesis proposes a new numerical technique: the eXtended Hybridizable Discontinuous Galerkin (X-HDG) Method, to efficiently solve problems including moving boundaries and interfaces. It aims to outperform available ...
Mena Andrade, Ramiro Francisco (Data de defensa: 2021-01-15)
Computer simulation is acknowledged as the third branch of Science. From the seminal work of Turner et al. (1956) [on Finite Elements, impressive improvements have been made in terms of software and hardware, so that, ...
Aidarov, Stanislav (Data de defensa: 2022-05-06)
Fibre reinforced concrete (FRC) has proven to be a suitable material for statically indeterminate elements. The FRC column-supported flat slabs with partial or even total substitution of reinforcing steel bars constructed ...
Carlesso, Débora Martinello (Data de defensa: 2020-03-06)
Fibre reinforced concrete (FRC) is recognized as suitable material for structural applications. The number of national codes that have approved it is an evidence. Structures where FRC is generally used can be subjected to ...
Ruiz-Orejón, Luis F. (Data de defensa: 2018-07-02)
Plastics are currently one of the most widely distributed litter in marine ecosystems worldwide. The floating fraction of these debris are estimated to represent about 1% of the plastics that enter into the marine environment ...
Tello Guerra, Alexis (Data de defensa: 2020-07-10)
The standard Fluid Structure Interaction coupling (velocity--pressure/displacement) is compared against two novel types of coupling, a Two Field coupling (velocity--pressure/displacement--pressure) and a Three Field coupling ...
Rausis, Kwon (Data de defensa: 2020-11-03)
This work discloses new insights into the formation and evolution of Mg -carbonates as well as carbonation processes of Mg-rich oxides and silicates with the aim of providing a safe and permanent anthropogenic CO2 storage, ...
Poliotti, Mauro (Data de defensa: 2020-11-04)
Modern guidelines for design and assessment of reinforced concrete structures under seismic and other extreme loads require nonlinear analysis. The complex structural response can be obtained by means of three-dimensional ...
Cornejo Velázquez, Alejandro (Data de defensa: 2020-12-21)
It is well known that in civil engineering structures are designed so that they remain,whenever possible, in an elastic regime and with their mechanical properties intact. The truth isthat in reality there are uncertainties ...
