• Controlling Fundamental Building Period

    I am running the seismic analysis for a 3 story structure and have questions about how to determine the appropriate building period to use for the seismic analysis. Gravity system is typical steel frame, with composite slab/framing at 2nd and 3rd Floors…
  • Design of Solid slab (Conventional slabs)

    Hello Everyone For a while, I was using an Advanced Concrete Design (RCDC) for the design of a solid slab. Today I tried to learn the RAM concept for the slab designs but I saw a design of strips that had never seen before (When I was using RCDC and…
  • Ram Steel Column: Can't turn off skip loading

    Hi, In RAM Steel Column, when I turn off the Skip-load the Live Load around column, it still shows skip load case as a controlling axial load in the report.
  • Illegal Framing Error - Can't Fix

    During beam design, it tells me I have an illegal framing error on beam 46. See layout below. I don't know which slab opening it doesn't like, but I also don't know a better way to draw them. One end of 46 is held by a small cantilever. On a related note…
  • Unbraced Length of Lateral Columns in RAM SS

    How shall we assign the unbraced length of lateral columns in a building with a mix of lateral and gravity columns supporting a flat slab? The building does have shear walls as well as a part of MWFRS. I know for gravity columns, it will be safe to…
  • Load Resistance of Shear Wall Cores in RAM SS

    I am analyzing a 350ft+ multistory building which contains a square shear wall core. RAM Frame analysis is giving me excessive deflections (more than what I expect given the core dimensions w.r.t. floor dimensions). I wanted to know if RAM Frame would…
  • 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…
  • 1-way deck distributing loads in other direction

    I have modeled a square one-way slab supported by 4 walls with 'other' material and have applied a surface live load of 40 psf. Theoretically, I would expect that only two walls would take all the load from the slab, but, both RAM Frame and RAM Concrete…
  • RAM SS - Concrete Column Design

    I have an issue where I have a concrete column that is shown as failing due to kl/r>100. The code reference for this error is given as 10.13.5. The problem with this is that I'm using ACI318-11, and that is an invalid code reference. In 318-11, 10.13…
  • RAM Elements/Structural System Composite Floor Design

    This is a multi-part question involving both RAM Structural System and RAM Elements. We have a composite floor supporting large process tanks via lugs in the center of several bays. The lugs are on load cells with very small deflection tolerances. …
  • RAM Plug-in

    Is there any way to create a plug-in, custom button, or any kind of custom command for RAM SS? I am curently automating RAM via Excel; but for useability, would prefer to impliment something within the RAM interface so that users don't have to open…
  • RAM SS - Grids

    In RAM Structural System v14.06, is it possible to copy a grid system to a new grid system so that the new grid system can be modified and still keep the old grid system? This would be helpful for projects that go through many revisions where you don…
  • RAM Connection and RSS 14.06

    Are Ram Connection 8.0.1 and RAM Structural System 14.06 compatible? I designed connections for a RAM model with 14.05.03 and 8.01 on my machine, but a coworker has upgraded to 14.06, and now he can't open the Connection file. Is there a workaround besides…
  • RAM SS - Wall transfer

    I'm modeling with RAM Structural System v14.06. I know that it is possible to have a column supported by a diaphragm. Is it possible to have a wall supported by a diaphragm and transferred through the (thick) slab to an offset wall below?
