Tunneling construction represents an alteration to the distribution of soil pressures that will almost inevitably generate ground subsidence, which can endanger the adjacent buildings in urban areas. The risk of building ...
Aunque el hormigón de alta resistencia se está utilizando de manera creciente en los últimos años para la construcción de estructuras, la norma Española vigente, la Instrucción EHE, sólo abarca hormigones de resistencias ...
Los sistemas modernos de construcción son asociados a tecnologías innovadoras y a los nuevos materiales, sistemas livianos que ofrecen la posibilidad de una mayor rapidez de ejecución por montaje. Estas características ...
Spatial Arch Bridges (SABs) are defined as bridges in which vertical deck loads produce bending moments and shear forces not contained in the arch plane due to their geometrical and structural configuration. Moreover, the ...
Tapered plate girders often form part of large-scale structures such as long continuous bridges or industrial buildings where due to considerable loads the higher resistance is required. There are several important reasons ...
Concrete technology has changed greatly in the past decades. Steel fibre reinforced concrete (SFRC) is an example of the development in this field. It is obtained by adding fibres that act as a reinforcement of the cement ...
The increasing use of the tunnel boring machines (TBMs) has entailed their own evolution and the improvement of the construction processes applied, allowing the construction of tunnels on more complex hydro-geological ...
Due to the related problems and the ongoing awareness on environmental issues is that efforts are put in different areas of knowledge, in order to determine, analyze and formulate solutions towards a sustainable future. ...
L'estudi del comportament i la verificació resistent de construccions de maçoneria, entenent per maçoneria qualsevol fàbrica de maó, de tovot, de pedra de paredar o de carreus, presenta diverses particularitats. En general, ...
Les escòries són el subproducte més abundant que s'obté en el procés d'incineració de residus sòlids urbans; constitueixen al voltant del 90 % en pes del producte sòlid resultant de la combustió. La producció anual a ...
The box-girder is currently the solution for large prestressed concrete bridges, being most used today in steel and mixed structures. Their widespread use is due to the strength characteristics and versatility, using various ...
This thesis examines the response of stainless steel members when subjected to transverse and normal forces triggering the instability phenomena called web crippling and local buckling, respectively. Currently, the part ...
