• RAM Frame Enhancement Request - Pseudo Flexible Diaphragms

    In RAM Frame, when assigning the load percentages for Pseudo Flexible diaphragms it will not recognize a frame number if that frame does not have a column in a particular diaphragm. Can we either get an enhancement to assign a column to multiple frames…
  • Staggered Ram Frame story shears

    I have a concrete core system where the Ram Frame story shears are plotted staggering like shown below. Why is this? I haven't had this issue on previous models I've made so it's concerning. Is it just a visual glitch or will it impact analysis/design…
  • RAM Frame AISC 360 Direct Analysis Method - Foundation Design

    For foundation design, do you check "Use Reduced Stiffness for Steel Members" when running RAM Frame module? It seems to give different Max Unfactored Soil Bearing for foundation design
  • RAM Frame AISC 360 Direct Analysis Method Cannot obtain T from Applied Forces Report

    Looking at ASCE 7 AISC 360 Direct Analysis Method guide, It states to get the period T with unreduced stiffness from Loads and Applied Forces report but mine does not show T. Can you help me obtain this T?
  • RAM Frame - Wind Load and Exposure for Girts and Non-Exposed Edges of Diaphragm

    Hello, I have a single-story roof with a high roof. At the location of the high roof, the wind load should be applied at the high roof and the girts. However, the generated wind load only applies load to diaphragms, so wind load is applied at the…
  • RAM Frame Exposure - New Building Adjacent to Existing Building

    I am creating a model of a building that is adjacent to an existing building on 2 sides, and exposed to wind on the other two sides, see snip below. There is an expansion joint between the buildings, so I am modeling the new building as a standalone structure…
  • Torsional Shear Ram Frame

    How does Ram SS calculate torsional shear on a shear wall for rigid diaphragm analysis? I am trying to verify my output with a few hand calcs, and the torsional shear on my shear walls in Ram Frame is less than I expect. For my hand calc of torsional…

  • RAM Frame - Unstable Structure Detected Instability Found At Rigid Diaphragm

    I am modeling a 5 story steel moment frame. One of my diaphragms is failing with P-Delta. I have went through the trouble shooting process of turning off P-Delta and running dead load, which is running fine. I can run wind and seismic without P-Delta…
  • RAM Foundation - Governing Load Combination

    Hello, I am currently working on a multi-phase building design, so I have two separate models, however, there are columns that will be located on the same footing at the expansion joint. Due to this condition, I am looking to design a combined footing…
  • What triggers a RAM Frame node renumbering?

    Is there a list of conditions under which node numbers in RAM Frame will renumber automatically? I assumed, incorrectly, that node numbers would likely stay intact if grids or columns moved but were not deleted, but that appears not to be the case. It…
  • Lateral Load Cases not generated with notional loads in load combinations?

    Hello, I have been working in a RAM SS building model for some time and it has been running without any problems. Yesterday, I shifted a grid that has braced frames on it. After that shift, RAM has been omitting my lateral load cases in the "x" direction…

  • P-Delta Excessive Deflection

    I have a model where I have modeled in some faux rooftop elements for exposure (domes and spire bases, spire loads input as nodal loads on the spire bases from another model). I am getting an excessive P-Delta deformation error for Story 6.33 ft Spire…
  • Axial force in beam RAM frame

    Hi, I have modeled knee braced frame as shown in imahe below. I am looking at the controlling axial load using member force envelope graphical mode. I see the values for min = -16.54 and max 3.21k. Therefore min value should control. However, when I…

  • Understanding Drift Results

    Hello, I am trying to understand drift results for my structure using RAM SS. We have semi-rigid diaphragms modeled and are trying to use the drift at control points to check the drift ratios. We have chosen select frame nodes coordinates as our control…
  • Moment Loads in Ram Connection vs Ram Steel

    Hello, I noticed that the moments shown in RAM Connection when accessing the drop down menu for loads in the base plate editor do not match the moments shown in RAM frame steel module when pulling a column member force envelope report. For instance…
  • RAM Frame Ground Level at Upper Floor - Reaction

    When I change the ground level as detailed here: LINK How can I find the reactions of the imposed global lateral restraints? Additionally, let's say that I want to eliminate the "overhang cantilever" affect that these global lateral restraints would…
  • Ram Frame Dynamic Load Case/ASCE 7 response Spectra Results not adding up

    I have a structure with a masonry level on top of 2 levels of cast in place concrete. I have created ELF, ASCE 7-16 response spectra, and Eigen Value load cases and scaled the response spectra per ASCE 7-16. I am finding that when I look at the building…
  • RAM Frame OCBF Chevron beam check - unbalanced load info missing
