  • Lateral Member Resting on Two-Way Slab

    In performing an integrity check in RAM Modeler, this warning appears: The High Roof level consists of columns, a 1-way 6" slab, and beams. The Level below consists of beams, columns, and a 2-way 12" slab supporting the High Roof columns: …
  • RAM Structural System Diaphragms and Lateral Loading

    Currently my 3 story RAM structural system model is calculating loads differently for each story when the roof diaphragm is switched from pseudo flexible to semi rigid. Additionally, when the roof diaphragm is semi-rigid, the load is applied to the perimeter…

  • RE: ram structural gravity or lateral

    You do have to preselect the columns and beams (and braces) that will be part of the main lateral force resisting system (moment frames or braced frames primarily). While you might expect the program to do this for you it's actually a lot simpler if you…
  • RE: How to input lateral systems in RAM

    Take a look at the tutorial (available from the Ram Manager help menu or installed to the local drive as a pdf). With Ram Structural System every beam and column is designated as either gravity (only) or lateral (lateral and gravity really). You can change…
