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 ...
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, ...
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 ...
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 ...
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 ...
Literature usually suggests that construction organization can reduce the costs derived from rework implementing quality management systems. Most common challenges and obstacles that construction organizations face during ...
En los últimos años la industria viene exigiendo el empleo del hormigón reforzado con fibras de acero (HRFA) en aplicaciones estructurales. Debido al hecho de que la resistencia pos-fisuración del material es relevante, ...
Durante un terremoto, las columnas de hormigón armado pueden verse sometidas a movimientos bidireccionales que pueden afectar su capacidad resistente y ductilidad. Sin embargo, las normas de diseño y evaluación sísmica no ...
En general, los materiales compuestos (MC) poseen la gran ventaja de tener una muy baja densidad con unas muy buenas propiedades mecánicas, permitiendo el diseño de elementos constructivos muy ligeros y una construcción ...
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 ...
Many reinforced concrete structures suffer damage due to aging and due to the environmental agressivity, thus affecting their serviceability performance and safety. Structural evaluation of a deteriorated structure is ...
The use of recycled aggregates in concrete opens a whole new range of possibilities in the reuse of materials in the building industry. This could be an important breakthrough for our society in our endeavours towards ...
This doctoral thesis addresses jointly two paramount aspects in the management of the hydraulic structures in operating regime: the damage diagnosis and the investment prioritisation that should allow repairing such damages. ...
Historical structures are vital to the realization of how the technical, artistic, and scientific skills of the human kind have developed over time. These structures are one of the motors of the tourism industry, and ...
La interacción microorganismo–hormigón es un proceso que, debido a la naturaleza porosa del hormigón, lo hace susceptible de ser colonizado por los microorganismos presentes en prácticamente todos los hábitats. Esta ...
Antoni Gaudí developed, for the pinnacles ofthe Sagrada Famí!ia, a unique constructive solution with precast concrete elements which were slightlyreinforced and covered with a trencadís ofMurano glass (Venice). In the ...
This doctoral thesis defines a new methodology for evaluating and comparing different construction projects in an objective and systematic manner. It is innovative by incorporating issues as diverse as cost, occupational ...
Portland cement is the most widely used building material. Is mainly composed of silicates, also has lesser proportion of aluminates and calcium sulfate. Its hydraulic nature generates in its hydration, the formation of ...
The conservation of historic structures has been given special attention due to their cultural, social and economic importance. However they often show considerable structural vulnerability and have been seriously damaged ...
