  • Special shear wall, Max Vert Bar Spacing Limit per ACI318-19, 18.10.6.5(a)

    Hi, I'm using the RAM structural system, and concrete module to run a special shear wall design. I specified a 2ft wide boundary zone on each size of the wall and RAM is giving me the following error. "Max Vert Bar Spacing Limit per, 18.10.6.5(a…
  • Fatal Error Internal Error in AdvanceNodeList()

    Hello I am working on a 5-story building that has wood frame with composite deck that’s being supported with steel beams/columns. When running the Steel Beam/Joist module, I get the below error for multiple walls and beams. I tried modeling new beams…
  • RAM Structural Systems: Design warning in transverse reinforcement for concrete beam

    Hello, I'm using RAM Structural Systems and while designing beams I came up with this warning in transverse reinforcement whenever I'm going for a spacing higher than 12in - "Shear bar max spacing exceeded by xx% per ACI 318-14 Sec. 9.7.6.2.2 for Bar…
  • Beam Review RAM SS

    As a confirmation, the deflection checks run in the beam design section of RAM Concrete are verified against the deflections caused by the load combos applied in the RAM Concrete Beam module. As such the load combos should reflect serviceability and not…
  • Dynamic Analysis- Capping Fundamental Periods

    I'm analyzing a structure with a dynamic analysis in RAM Structural System and notice that the fundamental periods are not being capped at CuTa per 12.9.1.4.1 of ASCE 7-16 when calculating the mass participation. Is there a reason for this? I don't see…
  • Live Load Reduction in RAM SS for columns

    I wish to seek clarification about how RAM SS calculates live load reduction for columns through an example. Suppose if we have a multistory building with 2-way decks supported by continuous columns. If we assign a live load reduction of 20% at 1st…
  • Non-load bearing walls

    How can i account for the non-load bearing walls in the model? I would like to account for these walls in the foundation design.
  • Is there anyway to update the concrete strength of all the foundations at once or do they need to be updated individually?

    Is there anyway to update the concrete strength of all the foundations at once or do they need to be updated individually?
  • RSS: Create New from ISM Repository?

    I'm trying to use the ISM (Integrated Structural Modeling) to get my Revit Structural Model into RAM so that my engineer can design the project. Yesterday I downloaded and installed the Structural Synchronizer and the ISM tool/add-in for Revit. I also…
  • M. Eng Students at Lehigh University use RAM Structural System for Final Group Project

    The Civil & Environmental Engineering department at Leigh University in Bethlehem, PA—like many engineering schools across the United States—offer a Masters of Engineering degree in addition to the more traditional Masters of Science in Civil Engineering…
