Granada, 24-27 de marzo de 2020. This paper presents an investigation on how to model a backfill masonry arch bridge using the discrete element method (DEM). The calculations that geotechnical engineers use the most today are elastic calculations, which use an elastic modulus “E”, or plastic analysis that check the equilibrium limit, through a cohesion “c” and a friction angle “”. There is an important problem here in determining these parameters. Soils are not homogeneous materials, but have a great variability. The micromechanics of particles arises here to solve these difficulties PFC2D software is used for this purpose. A certain backfill masonry arch bridge is modelled, with different types of fill, mortar and voussoir materials. Contact bonds and parallel bonds are installed to create the arch at a first stage, positioning balls by their center and radius. Secondly the fill is introduced in several layers and finally the arch is loaded until its collapse in three different load cases. A biaxial test has been programmed using ‘FISH’ code to obtain the micro-parameters used in the model so that they match the macro-parameters obtained from a real biaxial test. Also, a macro within a spreadsheet has been created to simplify the process of introducing the geometry of the arch. Further discussion on the influence of the DEM backfill parameters is presented as well as a sensitivity analysis for the arch bridge, specially with backfill parameters and load position. Advantages, disadvantages and limitations of this method of analysis are identified in relation to other frequently used methods. application/pdf eng Lombillo Vozmediano, Ignacio REHABEND 2020: Construction Pathology, Rehabilitation Technology and Heritage Management, p. 1149-1157 https://www.rehabend.unican.es/ Discrete Element Method Backfill Masonry Bridge PFC2D Geomechanical modelling Soil-structure interaction Ingeniería civil Resistencia de materiales Informática Civil engineering Strength of materials Computer science Influence of the backfill parameters in distinct element modeling (DEM) of a backfill masonry arch bridge through the PFC2D software info:eu-repo/semantics/conferenceObject info:eu-repo/semantics/publishedVersion info:eu-repo/semantics/openAccess THUMBNAIL Garcia-REHABEND_2020.pdf.jpg Garcia-REHABEND_2020.pdf.jpg IM Thumbnail image/jpeg 4482 https://riubu.ubu.es/bitstream/10259/8678/3/Garcia-REHABEND_2020.pdf.jpg c785d53475dde670b29f34bc00fab622 MD5 3 LICENSE license.txt license.txt text/plain; charset=utf-8 1362 https://riubu.ubu.es/bitstream/10259/8678/2/license.txt 5d013bfa6e473ff0db22cd82a4d71a70 MD5 2 ORIGINAL Garcia-REHABEND_2020.pdf Garcia-REHABEND_2020.pdf application/pdf 625072 https://riubu.ubu.es/bitstream/10259/8678/1/Garcia-REHABEND_2020.pdf 682dfa87cf3c1c7dfca18d9cab47d2fd MD5 1 10259/8678 oai:riubu.ubu.es:10259/8678 2025-02-03 09:47:24.603 Repositorio Institucional de la Universidad de Burgos bubrep@ubu.es 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
