    Article
    Open Access
    Additively manufactured thin-walled structures through selective laser melting (SLM) are of great interest in achieving carbon-neutral industrial manufacturing. However, residual stresses and warpages as well as recoater ...
  • A variational multiscale stabilized finite element formulation for Reissner–Mindlin plates and Timoshenko beams 

    Aguirre Ruz, Alejandro; Codina, Ramon; Baiges Aznar, Joan (Elsevier, 2023-05)
    Article
    Open Access
    The theories for thick plates and beams, namely Reissner–Mindlin’s and Timoshenko’s theories, are well known to suffer numerical locking when approximated using the standard Galerkin finite element method for small ...
  • Investigation on the down-aisle ductility of multiple bay pallet racks by means of pushover analyses 

    Bové Tous, Oriol; Casafont Ribera, Miguel; Bonada Bo, Jordi; Ferrer Ballester, Miquel; López Almansa, Francisco (2023-07)
    Article
    Open Access
    This paper presents numerical pushover analyses on multiple bay pallet racks, aiming to quantify variations in global ductility when using different beam-to-upright connections. The connections differ in the layout of the ...
  • Experimental study on a highly efficient shear transfer system for square CFST 

    Soltanalipour, Milad; Ferrer Ballester, Miquel; Marimón Carvajal, Federico; Albareda Valls, Albert; Casafont Ribera, Miguel; Iglesias, Gorka (Elsevier, 2023-03-16)
    Article
    Open Access
    A new shear transfer system for CFST columns is studied, which is an application of the patent EP2305911B1 into the square CFST columns. The new optimized system, called UPCCFST, consists of crown-shaped protrusions on the ...
  • Experimental and numerical study of the ductility of open-rib and reentrant composite slabs 

    Soltanalipour, Milad; Ferrer Ballester, Miquel; Marimón Carvajal, Federico (2022-04)
    Article
    Restricted access - publisher's policy
    The most restrictive failure mode of steel–concrete composite slabs is longitudinal shear. The partial connection method (PCM) is a design method for longitudinal shear capacity limited to slabs showing ductile failure and ...
