      Article
      Accés obert
      Microzonation is widely used in seismic risk evaluations to define the predominant period values, which are usually associated with extended areas of a few hundred meters. However, the representative values corresponding ...

    • Assessing the energetic and environmental impacts of the operation and maintenance of Spanish sewer networks from a life-cycle perspective 

      Petit Boix, Anna; Sanjuan Demás, David; Chenel, Sergio; Marin, Desiree; Gasol, Carlos M.; Farreny, Ramon; Villalba Mendez, Gara; Suárez Ojeda, María Eugenia; Gabarrell Durany, Xavier; Josa Garcia-Tornel, Alejandro; Rieradevall Pons, Joan (2015-06)
      Article
      Accés obert
      The environmental impacts resulting from sewer networks are best analysed from a life-cycle perspective to integrate the energy requirements into the infrastructure design. The energy requirements for pumping wastewater ...

    • Probabilistic seismic damage assessment of RC buildings based on nonlinear dynamic analysis 

      Vargas Alzate, Yeudy Felipe; Pujades Beneit, Lluís; Barbat Barbat, Horia Alejandro; Hurtado Gómez, Jorge Eduardo (2015-06-05)
      Article
      Accés obert
      The incremental dynamic analysis is a powerful tool for evaluating the seismic vulnerability and risk of buildings. It allows calculating the global damage of structures for different PGAs and representing this result by ...
