Climent Pera, Natalia (Date of defense: 2016-10-17)
During the oil recovery a hole is drilled, the sandstone is left unsupported next to the cavity and disloged sand grains can enter the oil recovery system. This process is called sand production and several problems may ...
Vasconcellos, Ramon Barboza de (Date of defense: 2021-05-18)
The thermo-hydro-mechanical (THM) behaviour of expansive clays has been extensively studied in the last decades due to the potential use of bentonites as components of engineered barrier systems (EBS) in deep geological ...
Kalkbrenner, Philip (Date of defense: 2021-11-03)
Cutting-edge methods in the computational analysis of structures have been developed over the last decades. Such modern tools are helpful to assess the safety of existing buildings. Two main finite element (FE) modeling ...
Zhang, Ningning (Date of defense: 2020-01-20)
This thesis explores the potential of models based on the discrete element method (DEM) to study dynamic probing of granular materials, considering realistic particle-scale properties. The virtual calibration chamber ...
Salvador, Renan Pícolo (Date of defense: 2016-12-12)
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 ...
García Díaz, Yineth Paola (Date of defense: 2023-09-27)
(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 ...
Alfarah, Bashar (Date of defense: 2017-06-09)
Under severe seismic excitation, structural behavior of buildings and other constructions is highly complex. It involves, among other issues, soil-structure interaction, large strains and displacements, damage, plasticity, ...
Parera Morales, Ferran (Date of defense: 2020-01-27)
The understanding of soil behavior is the foundation where the geotechnical engineering is built on. Experimentation is essential to improve this comprehension, and then to be able to translate it into models, theories, ...
Salami, Younes (Date of defense: 2017-01-11)
Au cours des dernières années, les analyses multi-échelles en mécanique des sols granulaires deviennent de plus en plus répandues. L’avantage de ce type d’approches réside dans leur capacité à établir un lien entre les ...
Kharazian, Alireza (Date of defense: 2017-11-23)
Collision between adjoining buildings is relevant, since the huge impact forces significantly modify the buildings dynamic behaviour. The separation required by the regulations avoids pounding; however, even in recent ...
Mánica Malcom, Miguel Ángel (Date of defense: 2018-10-11)
Materiales arcillosos rígidos, que se encuentran en la zona de transición entre suelos duros y rocas blandas, están siendo considerados actualmente en varios países como la roca huésped para el almacenamiento geológico ...
Hidalgo Leiva, Diego (Date of defense: 2017-01-30)
The damage assessment of structures under seismic actions, must seek the implementation of new theories, tools and procedures that reduce the uncertainty associated to the expected structural response of a building. This ...
Ávila Haro, Jorge Arturo (Date of defense: 2021-07-01)
Despite the fact that masonry is one of the oldest and most used building materials, the number of existing studies and experimental data, as well as the applicability of its results (i.e. extrapolation), are substantially ...
Díaz Alvarado, Sergio Alberto (Date of defense: 2017-09-18)
The main objective of this thesis is the probabilistic assessment of the expected seismic damage in steel buildings located in Mexico City. Although a deterministic analysis is performed both, seismic actions and buildings, ...
Rodríguez Frete, Mariana (Date of defense: 2020-12-16)
Concrete is one of the most used materials in construction, and its application spans to all kinds of structures. For this reason, concrete has been the subject of intense study. In spite of that, there are still apects ...
López Carreño, Rubén-Daniel (Date of defense: 2018-07-31)
The construction and conservation of road networks represent a major part of public expenditure. For instance, the EU-28 countries annually spend approximately EUR 20.000 million on roadway preservation. These figures ...
Emadi, Seyyedbehrad (Date of defense: 2020-12-11)
According to Timoshenko’s beam theory, nodal rotations in beam-like structures are produced by bending and shear effects. On the one hand, bending rotations can be easily calculated by the Euler-Bernoulli stiffness matrix ...
Vieira, Mylene de Melo (Date of defense: 2018-10-19)
High performance steel fibre reinforced cementitious composites (HPSFRCCs) show enhanced structural performance and durability. The improved properties favour its use in agressive conditions (such as marine environment) ...
Santos Rodríguez, Cristian de (Date of defense: 2015-12-10)
Nowadays, thanks to the increase of computers capability to solve huge and complex problems, and also thanks to the endless effort of the geotechnical community to define better and more sophisticated constitutive models, ...
Alavi, Hamidreza (Date of defense: 2022-10-11)
A Decision Support System (DSS) can help facility managers to improve building performance, occupants’ comfort, and energy efficiency during the Operation and Maintenance (O&M) phase. These DSSs are normally data-intensive ...
