  • OptiBridge: a topology optimized 3D-printed concrete bridge
    Overview Ghent University has built a second topology optimized concrete footbridge named OptiBridge The 5-metre-long bridge girders were based on a 2D topology optimized design by Technion - Israel Institute of Technology (Team led by Prof Oded Amir) and redesigned at Ghent University by Ticho Ooms and Gieljan Vantyghem into a realistic 3D structure
  • 3D Printed Concrete Bridge | Designed by topology optimization
    Ghent University has built a second topology optimized concrete footbridge named OptiBridge The design of the 5-metre-long bridge girders were based on a 2D
  • 3D-Printed Concrete Bridge Designed by Topology Optimization - ResearchGate
    The 2D shape of this girder was optimized using topology optimization techniques developed at Technion - Israel Institute of Technology For this girder design, not only the concrete distribution was
  • The Production of a Topology-Optimized 3D-Printed Concrete Bridge
    The topology of the girders is based on a result from the work of Amir and Shakour [] Similarly, the resulting 2D image (see Fig 2a) is used as a template for the base geometry and converted into a 3D shape (see Fig 2b) by means of parametric modelling in Rhinoceros Grasshopper This process facilitates adjustments in the pre-design stage
  • Optimization of prestressed concrete bridge girder section using a . . .
    Aydin and Ayvaz [5] shows that, besides the girder geometric properties, it is important to include the number of prestressed beams at the bridge superstructure cross-section as a design variable in order to obtain a more economical solution It is obvious that the overall economic impact increases with higher optimization levels as well as optimizing the overall bridge system leads to more

  • OptiBridge: Una nueva metodología de construcción con hormigón 3D
    Esta nueva metodología, bautizada como OptiBridge, abarca distintos ángulos del elemento fabricado -en este caso, un puente- como su reología, Diseños mejorados a partir del 2D Uno de los primeros aspectos que abarca esta nueva metodología es el del diseño Para ello, se planteó un paso peatonal de 2 metros de ancho por 5 de largo
  • An optimal concrete bridge — Department of Structural Engineering and . . .
    The concrete printer brings the 3D model alive (left) - An optimal bridge shape that requires the smallest amount of concrete The trajectory of the steel cable was correspondingly optimized (right) During printing of the bridge, the researchers provided a cavity in the bottom of the bridge to pull a cable through afterwards
  • OPTIBRIDGE Bridging agent selection software - SLB
    Using formation data and information about potential materials, OPTIBRIDGE software calculates the best fit or mixture of bridging particles to pack your formation effectively It determines the ideal particle size distribution for the bridging material, with blends that form a tighter and less invasive filtercake to seal pores, fractures, or completion screens
  • Parametric modelling of 3D printed concrete segmented beams with rebars . . .
    Ghent University has presented other examples such as the topology optimization of a small 3D printed pedestrian walkway bridge [23], [24], with 2 × 5 m dimensions and designed using mathematical optimization tools In the first stage, a 2D optimization of the beams was performed, then a 2D optimization script set an optimum stiffness for both sides of each beam, and finally, the optimized
  • The Production of a Topology-Optimized 3D-Printed Concrete Bridge
    The Production of a Topology-Optimized 3D-Printed Concrete Bridge 39 The length of the new bridge is 4 75 m and the width varies between 1 4 m (deck) and 1 9 m (girders) The bridge deck has a variable thickness with a minimum of 0 12 m at the mid span to 0 22 m at the edges, while the depth of the beams is 0 6 m
