Martínez Estévez, Ariadna (Date of defense: 2020-06-29)
In order to cope with the serious and urgent problem of global warming, it is imperative to reduce the impact of CO2 emissions in the atmosphere. One of the alternatives proposed involves the injection of the CO2 in deep ...
Quirós Collazos, Lucía (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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. (Date of defense: 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 (Date of defense: 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 ...
Janeras Casanova, Marc (Date of defense: 2023-10-23)
(English) In the Montserrat Mountain, high hazard of rockfall and high human exposure by visitors to both Monastery and Natural Park converge. It is a relevant geological risk difficult to mitigate since it is necessary ...
Rausis, Kwon (Date of defense: 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, ...
