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 ...
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 ...
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. ...
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 ...
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 ...
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 development of the wet-mix system and the use of the sprayed concrete as a part of the new Austrian tunnelling method (NATM) marked an increase in the use and in the structural responsibility of the material, with ...
The use of fibre reinforced concrete (FRC) as a construction material has expanded beyond the traditional applications since the publication of design codes and guidelines. In fact, the industry is demanding FRC with ...
This work presents a study of the simulation of cable-stayed bridges built on temporary supports focused on their response during construction and in service. To simulate the behavior during construction, a set of four ...
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 ...
Molts dels problemes i obstacles que més freqüentment han d’encarar les empreses constructores durant el procés d’implementació i ús de sistemes integrats de gestió mediambiental i de seguretat i salut estan relacionats ...
The aim of this thesis is to present a framework for the application of micro-modeling techniques for the analysis of unreinforced masonry structures. Finite element analyses of case studies from the literature are carried ...
The development of methods that correlate the measure of dynamic parameters with the condition of the structure has received a considerable attention from the engineering community in the last few years. In the field of ...
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 ...
Water is one of the fundamental components of concrete, not only for its role on the hydration of Portland cement, but also because of the physical functions it develops, which are associated with the main phases of concrete ...
To make the inspection and diagnosis of buildings is useful be able to quantify how far the existing deficiencies are serious or not, in order to facilitate the decision making and prioritize therapeutic interventions. In ...
La metodología utilizada y las fases principales del trabajo han sido: * Realización del estado del conocimiento englobando el estudio de la calidad en el sector de la construcción y concretamente en la realización de ...
