Villar Salinas, Sergio (Date of defense: 2023-12-15)
(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 ...
Wang, Xuejing (Date of defense: 2023-11-28)
(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 ...
Morey Gual, Lluís (Date of defense: 2023-11-17)
(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 ...
González Flórez, Cristina (Date of defense: 2023-10-06)
(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 ...
Segura Valdivieso, Guillermo (Date of defense: 2023-09-22)
(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 ...
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 ...
Stamatopoulos, Georgios (Date of defense: 2023-07-07)
(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 ...
Moaven, Arash (Date of defense: 2023-07-04)
(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 ...
Bertran Oller, Oriol (Date of defense: 2023-07-11)
(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 ...
Su, Hang (Date of defense: 2023-06-19)
(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 ...
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 ...
Martín Balet, Alejo (Date of defense: 2023-06-23)
(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 ...
Eskenati, Amir Reza (Date of defense: 2023-06-09)
(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 ...
Baquero Mosquera, Juan Sebastián (Date of defense: 2023-06-22)
(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 ...
González de León, Isabel (Date of defense: 2023-05-19)
(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 ...
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 ...
Muñoz Liesa, Joan (Date of defense: 2022-07-20)
(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 ...
