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 ...
A model for the non linear dynamic analysis of reinforced concrete and masonry framed structures
La evaluación de la respuesta dinámica o sísmica de estructuras complejas a menudo requiere de la integración en el dominio del tiempo de la ecuación de equilibro dinámico de la estructura, en el marco de un análisis no ...
A model for the nonlinear, time-dependent and strengthening analysis of shear critical frame concrete structures
Nonlinear fibre beam models, due to its intrinsic simplicity and computational efficiency, are often an adequate alternative to the complex nonlinear plane and solid FE models for the assessment of entire frame structures. ...
A non-linear coupled model for the analysis of reinforced concrete sections under bending, shear, torsion and axial forces
La mayoría de las estructuras de hormigón armado se someten a solicitaciones combinadas de esfuerzos axiles, flexión, cortante y torsión. La fisuración del hormigón, plastificación de las armaduras y otros efectos no-lineales ...
Accelerated cementitious matrices : hydration, microstructure and mechanical strength
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 ...
Activación alcalina de residuos urbanos e industriales para la construcción de piezas prefabricadas
(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 ...
Analysis of cantilever construction of concrete cable-stayed bridges with time-dependent phenomena
(English) This work presents a study on the construction analysis of cable-stayed bridges built by the cantilever method, with a particular focus on the effects of time-dependent phenomena such as creep and shrinkage. In ...
Análisis de valor en la toma de decisiones aplicado a carreteras
Con frecuencia los modelos de evaluación aplicados a carreteras consideran aspectos relativos a la funcionalidad, seguridad, comodidad del usuario, medioambiente, etc. Sin embargo, dichos aspectos pocas veces son evaluados ...
Análisis numérico de presas de hormigón bajo acciones expansivas
The main objective of this thesis is to study the mechanical behavior of a dam concrete under internal expansive phenomena in both the macro-structural and the meso-structural level. An important contribution of this work ...
Aplicabilidad de la ceniza volcánica de baja actividad como nuevo recurso para materiales cementicios sostenibles
(English) Volcanic ash (VA), abundantly available in various regions globally, serves as an effective supplementary cementitious material (SCM) for partially substituting Portland cement (OPC). However, its inherently low ...
Aportaciones al estudio del comportamiento a flexión de estructuras de acero inoxidable
L'acer inoxidable està essent utilitzat de manera creixent en els últims anys als sectors de la indústria i de l'arquitectura gràcies a la seva resistència a la corrosió, facilitat de manteniment i aparença agradable. Però, ...
Aportaciones al proyecto, construcción y reparación de pavimentos de hormigón
The construction and conservation of road networks represent a major part of public expenditure. For instance, the EU-28 countries annually spend approximately EUR 20.000 million on roadway preservation. These figures ...
Application of BIM visual programming algorithms for infrastructure projects
(English) The BIM digitization has generated a growing automation of traditional AECO project development processes. However, this automation has mainly benefited building projects, which has generated a critical gap in ...
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 ...
Aspectos tecnológicos de túneles construidos con tuneladora y dovelas prefabricadas de hormigón
El número de túneles construidos con tuneladora tipo TBM ha aumentado considerablemente en las últimas décadas en consecuencia de los avances tecnológicos observados en estas máquinas y en el propio proceso constructivo. ...
Assessment of chloride corrosion in steel fibre reinforced cementitious composites
High performance steel fibre reinforced cementitious composites (HPSFRCCs) show enhanced structural performance and durability. The improved properties favour its use in agressive conditions (such as marine environment) ...
Bi-layer diaphragm walls : experimental and numerical analysis
Leakage is a widespread problem associated with the construction of diaphragm walls whenever they are erected in water-bearing ground. The aim of the present research is to develop a new type of slurry wall: the bi-layer ...
Bioreceptivity optimisation of concrete substratum to stimulate biological colonisation
The lack of green areas in cities is caused by the increase in population and the urbanisation process. However, an increasing interest in city greenery was observed since the beginning of twentieth century. Several benefits ...
Building information modeling for facility managers
A Decision Support System (DSS) can help facility managers to improve building performance, occupants’ comfort, and energy efficiency during the Operation and Maintenance (O&M) phase. These DSSs are normally data-intensive ...
Caracterización de las propiedades del hormigón autocompactante asociadas al esqueleto granular
En el disseny y la caracterització del formigons autocompactants (HAC) tenen implementació tant els propis components de la mescla (volum de pasta y naturalesa de la mateixa, tipus i contingut de fi, estructura del esquelet ...
