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 ...
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 ...
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. ...
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 ...
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 ...
(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 ...
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 ...
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 ...
(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 ...
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, ...
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 ...
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 ...
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. ...
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) ...
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 ...
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 ...
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 ...
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 ...
En esta Tesis Doctoral se abordan aspectos de gran interés en relación a la caracterización del HRFP, la definición de una ecuación constitutiva considerando la orientación de las fibras, y el comportamiento diferido del ...
Despite the advance that has led the incorporation of Annex 15 in the Spanish EHE-08, the use of recycled aggregate concrete (RAC) is minimum in structural applications. This regulation limits the percentage of substitution ...
