Structural system identification by dynamic observability technique
Structure system identification (SSI) can be classified as static and dynamic depending on the type of excitation. SSI by Observability Method (OM) using static tests was proposed and analyzed to address the observability ...
Risk-based highway bridge inspection intervals
Infrastructure maintenance programs establish schedules for routine inspections of highway bridges with little consideration of their current conditions. The time interval between two inspections is traditionally set based ...
Seismic vulnerability assessment of traditional timber frame and masonry wall buildings : aplication to the historical centre of Valparaíso, Chile.
The seismic vulnerability of urban assets exposed to earthquake hazard represents a growing concern in the engineering field due to the potential risk of collapse for the buildings, and the associated devastating consequences ...
Integrated solutions for the energy and seismic retrofit of existing buildings
European building stock is characterised by low energy efficiency and high structural vulnerability with respect to earthquakes, especially in seismic prone areas like Italy. In fact, the vast majority of buildings has ...
Laboratory experimental procedures for the compression and shear characterisation of historical brick masonry
Masonry has been used for millennia to build all sort of constructions. As a result, a significant part of the building stock around the world is made of masonry. In the need of structural assessment, structural analysis ...
Structural diagnosis of masonry heritage : contributions to non-destructive testing, structural health monitoring and risk assessment.
Many cultural heritage sites across the globe consist of masonry structures. To ensure the preservation of such structures, an accurate evaluation of their current structural condition is often of utmost importance. However, ...
Seismic retrofit of masonry with innovative materials for strengthening and repair
As one of the main historical construction materials, masonry is abundant among the architectural heritage of earthquake-prone areas of the Mediterranean countries. Earthquake mitigation approaches are now focusing on ...
Application of observability techniques to structural system identification including shear effects
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 ...
A framework for 3D nonlinear analysis of reinforced concrete frames under general loading
Modern guidelines for design and assessment of reinforced concrete structures under seismic and other extreme loads require nonlinear analysis. The complex structural response can be obtained by means of three-dimensional ...
Flexural fatigue of pre-cracked fibre reinforced concrete: experimental study and numerical modelling
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 ...
Desarrollo de hormigones conductores con adición de fibras de carbono recicladas
Inside the studies of intelligent materials and considering concrete as one of the most building material used, getting new functionalities to him, would provide new uses and applications to the usual structural or facing ...
Estudio de la escoria de acería de HAE: aspectos expansivos y ambientales
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 ...
Impact assessment of the façades' actual state on the energy performance gap of residential buildings
Bridging the gap between the predicted and actual energy performance of buildings is necessary to increase the energy performance of existing buildings and achieve the European Union’s energy efficiency targets in the “2030 ...
Lean construction versus Project Management in road projects : scheduling comparison
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 ...
Station keeping analysis and design for new floating offshore wind turbines
In the framework of the reduction of the emissions of greenhouse gases, FOWT will be the technology that will exploit the wind resources in deep seas. In order to achieve a commercial deployment of this technology, a cost ...
Geometrically non-linear analysis with stiffness reduction for the in-plane stability design of stainless steel frames
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) ...
Theoretical and experimental study of the behaviour at service and failure of partially prestressed concrete beams under flexure and shear
Partially Prestressed Concrete (PPC) is an intermediate design approach between reinforced and totally prestressed concrete, that enables controlled cracks in service phase. Conversely, totally prestressed concrete is ...
Intercalation mechanism of polycarboxylate-based superplasticizers into montmorillonite clays
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. ...
Development of optical fibre distributed sensing for the structural health monitoring of bridges and large scale structures
In this doctoral thesis it is proposed to research and assess the performance of the use of distributed optical fiber sensors (DOFS), more specifically the case of the optical backscattered reflectometry (OBR) based system, ...
Enhancing building performance : a Bayesian network model to support facility management
The performance of existing buildings is receiving increased concern due to the need to renovate the aging building stock and provide better quality of life for end users. The conservation state of buildings and the indoor ...
