The microstructure, understood as the distribution of pore sizes and their connectivity, is an important factor that affects the mechanical behaviour and the hydraulic properties of compacted soils with fine fraction (silts ...
Concrete is a complex material and can be modeled on various spatial and temporal scales. While simulations on coarse scales are practical for engineering applications, a deeper understanding of the material is gained on ...
The urban tunneling may generate significant problems. One of the main concerns is the unavoidable ground movements generated; before, during and after the tunneling operations. In this context, the objective of this Thesis ...
Electric Arc Furnace Slag (EAFS) is the by-product generated in the steel making process in electric arc furnaces. According to the European slag association, EUROSLAG, 18,4Mt of steel slag have been reported, of which ...
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. ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
In AISC 360-16, the Direct Analysis Method (DM) has been set as the primary method for the stability design of frames. DM, considering initial global sway imperfection, is essentially Geometrically Non-linear Analysis (GNA) ...
The hydro-mechanical behaviour of MX80 bentonite pellet-based mixture (80% high-density pellets in dry mass and crushed granular powder) has been explored in this thesis within the context of the French ‘Vertical Sealing ...
Construction and demolition waste (CDW) is a major environmental concern that requires immediate attention. The large volumes of CDW produced and its associated environmental effects have led to explore new alternatives ...
A large number of underground works are under construction in several big cities around the world (London, Paris, Amsterdam, Beijing, Shanghai, Chicago, Caracas, Mexico D.F., and Riad, for instance): railway tunnels, water ...
This thesis aims to studythe capacities and limitations of Ground Penetrating Radar (GPR) to support inspection, assessment, maintenance and rehabilitation tasks, helping to earlydetection and evaluation ofpathologies in ...
The presence of clays in the sands used for concrete production interferes with the development of the fluidity of concrete, producing an instantaneous slump loss just after batching and the premature loss of fluidity. ...
Lean Construction is regarded as an innovative approach of management for various types of projects in the field of construction. As much as it is currently applied in some countries, its expansion is inevitable, for better ...
The aim of this work is the study of laboratory effects on the measurement of wave impact induced loads on rigid maritime structures. A high number of experiments (more then 4000 using regular wave attacks) have been carried ...
(English) Masonry structures are among the most abundant construction typologies in the world, having been commonly built until the second half of the 20th century. The determination of the mechanical properties of these ...
