• FE-Mesh: Move and Rotate the Nodes

    The RM Bridge Analyzer: Properties: Cross Sections: FE Mesh Move and Rotate the Nodes is a button with an option to modify current cross-section properties to achieve specific purposes. It is important to note that this function is principally related…
  • PlElUlt for Normal / Join / Split Results

    In OBD CE 2021 Release 2 and RM Bridge v11.13, was implemented the Plot element cross-sections for ultimate capacities using different types of force component selections namely: Total: Normal, Total: Split and, Total: Join . Join results Split…
  • Curved Cross-section Elements

    RM Bridge can create curved circular cross-section elements with the use of additional definitions for the Rounding of elements' edges. As shown below, this will apply one constant radius value to one of the sides of the element. For accuracy or when…
  • Modeler: Import existing Cross-sections

    In OpenBridge Designer , at the RM Bridge Modeler , by using the right-click mouse at the Cross-Sections list in the menu tree, it is possible to import existing or Read Cross-section from: Steel Profiles: I or T Rolled or Welded, L, U, C, Rectangular…
  • RM Bridge FAQ: Modeling inclined pylon

    For modeling an inclined pylon in RM Bridge the user can either have the cross-section of the element in-plane, with the usual option of the cross-section plane horizontal, or perpendicular to the element axis. These inclined element cross-sections…
  • Reinf crack for prestressed concrete

    Hi all. I have a question about Reinf crack for prestressed concrete as follows: If you calculator stress bot of section beam in MinMz_Service exceeding allowable stress tension limit is 0,5 x sqrt(f'c), you can calculator reinf area to control crack…
  • How to change deck width and offset (when ABC is grayed out)

    When working with a full bridge the deck width can be changed from the LBC > Geometry tab Open the LBCX file and navigate to Geometry tab Expand Roadway Elements and select XCECT01 from the tree under Selection on the left: In the Cross…
  • How to transition in superelevation or vary deck width in ABC Wizard

    Basic bridge cross sections can be defined in LEAP Bridge Concrete to describe the roadway surface. Individual cross sections are referred to as templates, and the collection of templates constitute a cross section set. A cross section template is composed…
  • Longitudinal Section in OpenBridge Connect version. Is it possible to follow the alignment of the bridge?

    Hello to everyone, I would like to know if someone knows if it is possible to create a longitudinal section of a bridge along its alignment so that if the bridge is in horizontal curve I can get the real longitudinal profile? Perhaps it is possible…
  • RM Bridge - Stress calculation for asymmetric sections

    Our firm noticed, during the design of a hollow box bridge with inclined top slab (curved bridge with 7% transversal slope), that elastic stress calculation performed by RM bridge is not correct. In fact, even if it's possible to model generic cross sections…
  • RM Bridge- Modelling Plan variation of Box Section

    How to model the concrete box section varying width in Plan as shown below?
  • RM modeling inclined pylon

    when input cross section of pylon segment, it is convenient to place cross section geometry on a plane perpendicular to gravity. one special case when pier element local axis is not perpendicular to the horizontal plane, it seems reasonable to choose…
