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. ...
(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 ...
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 ...
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 ...
Pervious concrete is a special material with high permeability usually obtained by reducing the amount of fine aggregates in the composition of concrete. The properties of pervious concrete not only depend on its composition ...
The use of the EAF steel slags as aggregate in the production of concrete has gained great interest with the increasing concern about the environment impact and the sustainability in the construction industry. The EAF steel ...
Pervious concrete is a special material with high permeability usually obtained by reducing the amount of fine aggregates in the composition of concrete. The properties of pervious concrete not only depend on its composition ...
La función primaria de la estructura es resistir las acciones a las que estará sometida. La resistencia de la estructura debe entenderse en sentido amplio y no restringirse solamente a la resistencia mecánica de las ...
Este trabajo de investigación presenta un estudio sobre el comportamiento de los puentes de dovelas de hormigón con pretensado exterior y juntas secas conjugadas, centrándose en el estudio de la respuesta a solicitaciones ...
Hoy día está ampliamente reconocido que la estructura de la matriz de cemento en las proximidades de los áridos, es distinta a la del resto de la pasta, aunque dicha microestructura de la zona interfacial es variable en ...
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 ...
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. ...
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 ...
This thesis investigates the cross-section and member behaviour of cold-formed stainless steel RHS and SHS elements and proposes an alternative and more efficient design approach. Combined with aesthetic appeal, exceptional ...
The external sulfate attack (ESA) is a complex degradation process typically compromising the durability of underground foundations, nuclear or industrial waste containments and tunnel linings exposed to sulfate solutions. ...
This thesis discusses the development of a new methodology for 3D printing of TiO2 nanoparticles and its applications in air purification and hydrogen production. A dosage has been obtained that allows 3D printing by DIW ...
The use of externally bonded fibre reinforced polymers, FRP, for strengthening reinforced concrete (RC) beams or columns is an alternative to other traditional strengthening techniques due to its high strength-to-weight ...
A pesar de que los forjados de vigueta pretensada y bovedilla se han utilizado desde los años 40 en prácticamente todo el mundo, los modelos que actualmente se utilizan para su cálculo frente al Estado Límite Último de ...
