Consideraciones relativas al diseño y a la alta durabilidad de dovelas de hormigón reforzado con fibras no metálicas (HRFnM)
The use of the fibre reinforced concrete (FRC) as a construction material has expanded beyond the traditional applications since the publication of design codes and structural guidelines. Fibre reinforced concrete for ...
Seismic design of steel beam-to-column joints with reduced beam section using European hotrolled
The design rules on Reduced Beam Sections (RBS) are covered in the Eurocodes in EN1998-3 as a possible solution to improve rotation capacity of beams for the retrofit of existing structures. The design rules are very similar ...
Study on the shear and punching-shear strength of reinforced concrete slabs subjected to point loads and in-plane tensile forces
Reinforced concrete members, especially when subjected to concentrated loads, can fail in shear. This is an undesirable and brittle failure mode preventing the structure from deforming and reaching higher load levels. It ...
A machine learning based material homogenization technique for masonry structures
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 ...
Recomendaciones para el proyecto de puentes de ferrocarril con aparatos de apoyo de núcleo de plomo (LRB) en zonas sísmicas
Railway bridges located at seismic zones are particularly complex structures that present exceptional difficulties due to the existence of the track and the phenomena associated to it called track-bridge interaction. The ...
Structural behaviour of masonry arches on moving supports : from on-site observation to experimental and numerical analysis
Since ancient times, master builders have used arches to cover large spans in masonry structures. As a consequence, nowadays the safety assessment of these structural elements plays a fundamental role in the conservation ...
Performance of distributed optical fiber sensors embedded inside reinforced concrete structural elements.
The employment of a novel cutting edge strain monitoring technique named Distributed Optical Fiber Sensors (DOFS) as Structural Health Monitoring (SHM) tools is becoming increasingly common. Its popularity can be attributed ...
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 ...
