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 ...
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 ...
This thesis discusses which transit network structure is the best option to serve urban mobility. As a consequence of the evolution of urban form, cities have undergone a dispersion process of their activities. This fact ...
This thesis presents a study of the mechanical behaviour of coarse-crushable aggregates, using the discrete element method (DEM). A novel DEM model has been developed taking into account particle breakage, the influence ...
Evidence from progressive deterioration of the urban building stock is well known. This brings about a large social and economic impact due to maintenance costs and associated personal hazards. This thesis explores ways ...
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 ...
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 ...
Artificial recharge of aquifers through infiltration basins (AR) improves water quality and in- creases groundwater resources, which make of it an appropriate technique for the renaturalization of waters affected directly ...
Dam behaviour is difficult to predict with high accuracy. Numerical models for structural calculation solve the equations of continuum mechanics, but are subject to considerable uncertainty as to the characterisation of ...
This thesis focuses on the numerical modeling of fracture and its propagation in heterogeneous materials by means of hierarchical multiscale models based on the FE2 method, addressing at the same time, the problem of the ...
This thesis presents the study of the model order reduction for power grids and transmission networks. The specific focus has been the transient dynamics. A mathematical viewpoint has been adopted for model reduction. Power ...
Micro-seismicity, and especially felt seismicity, induced by Enhanced Geothermal Systems (EGS) operations is a matter of scientific interest, not only because of the related risks and concerns, but also because the ...
In this research, the seismic response, the vulnerability and the expected damage in rein-forced concrete residential buildings, with irregular plants, are analyzed. This irregularity is mainly due to inbound and outbound ...
In the Amazon region, few data are available on the impacts caused by the urban settlements found in the proximity of estuaries. In the estuary of the Caeté River, the focus of the present study, the nutrient input is ...
Strain localization and quasi-brittle failure in frictional-cohesive materials is still an open and challenging problem in computational mechanics. Owing to its complexity and the significant implications on numerous ...
Rockfill is a coarse material widely used in geotechnical works such as earth-fill dams (shoulders and toe drains), as well as in embankments and well-graded quarry materials for railway infrastructures. These structures ...
Anthropogenic pollution represents a major concern for aquatic ecosystem, which has been affected by a complex cocktail of heterogeneous compounds that may provoke significant toxic effects to the living organisms. Among ...
Stroke is a major cause of death and disability in Spain and in the Western world. It is often caused by an accumulation of atherosclerotic plaques on the walls of carotid arteries. Carotid revascularization may be the ...
The present dissertation aims at addressing multiscale topology optimization problems. For this purpose, the concept of topology derivative in conjunction with the computational homogenization method is considered. In ...
Deep geological disposal remains the preferred option at present for the management of long-living and heat-emitting radioactive waste, which consists of confining the waste during a very long period (several hundreds of ...
