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…

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…

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

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?

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…

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…

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…

I am getting this warning: WARNING- Deflection check of member # 11 will not be performed as DFF value not provided. I am sharing the input command. Please provide your view. STAAD SPACE START JOB INFORMATION ENGINEER DATE 15-May-23 END JOB INFORMATION…

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…

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…

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…

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…

ASSIGMENT-6.std ON RUNNING THIS ERROR COME ,,PLEASE GIVE ME SOLUTION TO RESOLVE THIS , I HAVE TRY ALL THE METHOD GIVEN PREVIOUSLY

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…

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…

I am analyzing this braced frame structure with the effective length method following this procedure https://communities.bentley.com/products/ram-staad/w/structural_analysis_and_design__wiki/55456/asce-7-aisc-360-and-the-effective-length-method-in-the…

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…

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…

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…

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…

For some reason, RAM Frame is not reporting the unbalanced brace loads in the Seismic Provisions > OCBF-V beam output. Is this a software bug or did I miss a setting somewhere?

I have rigid diaphragms at each level with 8 moment frame beam lines in the Y direction and 4 moment frame beam lines in the X direction. I have Loads and Applied Forces report that shows the diaphragm forces at each level. What is the best way to extract…

I have a 6-story BRB model that runs fine. As soon as I add a seventh story (diaphragm is different than stories below), I get an unstable structure detected. The node for which the instability is found occurs in the middle of the diaphragm. I have column…

Hi, When I am running RAM frame for Tilt up building, and the analysis does not converge because of too low of crack factor, the error window points to a wrong panel. Is there a better way to troubleshoot which panel is giving me an error?
