Why doesn't the program calculate Cs per equation 12.8-5 ? Cs used is calculated from Eq 12-8-3. If calculated per 12.8-5 the Cs=0.044xSds=0.046 (which is the minimum Cs value to be used) is greater than 0.034.

Why are the Sds, Fa different for the same site class D between ELF and Dynamic load cases ? Please let me know. Thanks!

Hey, I have a composite deck..When I check a particular beam's report I get a 1.4D Mu= 528.6 kip-ft and in the diagrams I can the dead moment 1.4D is 702.07kip-ft. Could you please let me know why the values are different? Please see attached file. Thanks…

We've been using RAM since the 1990's. In the past, I kept our settings consistent from station to station and when we bought new computers by copying the RamIS.ini file from one computer to the next. When we upgraded to all new Windows 10 workstations…

Hi everyone, We are trying to use RAM Steel to help us design the gravity system of a building utilizing a long span, deep deck system. Has anyone else used similar systems before and have any tips or tricks? Additionally, does anyone know if RAM…

Looking at the reports for a typical composite beam in RAM Structural System, I am seeing that RAM outputs I-effective (Ieff) and I-transformed (Itr) that are different from those listed in AISC Table 3-20 (Lower Bound Elastic Moment of Inertia for Plastic…

Hello , I know there is a way to get the results for frame members from post-processing for each load cases which also includes D and L. Similarly is there a way to get the results for the gravity steel members?

Hey I have a situation where column is outside defined slab edge? What are the implications of this? Please see pic below:

Hello, I am wondering how RAM Steel computes the I_{tr} for composite beams. For example, I have a composite beam with the following properties as computed by RAM: But by hand, I am computing I_{tr} = 941.86, slightly less than RAM. I am guessing…

Hello, I am working on a school project, so I am not experienced, just to be clear. But I have a slab openings on my floors for stairwells and elevators in the RAM modeler. However, my understanding is that RAM won't apply floor loads where there…

I have a model with 20 stories and most have a unique layout type. However, most of them share a common core of slap openings for elevators, stairs, etc. If I have to make a change on a number of these, I have to manually go and make that same change…

I just go a more recent version of RAM SS and when I run the beam module there are certain beam that now show that they fail in deflection. But when I look at the report the beam does not fail in deflection. I have tried deleting the beam and putting…

This is the first time this has happened to me, but point loads that I placed on a beam in the RAM modeler are not acting on that beam when checked in the beam/joist module. However, they are acting on a different beam along the same construction grid…

I have floor plate with composite beams and uniform loading but for some reason a couple beams in the top right corner are being designed with partial loading and beam sizes that are substantially larger than the rest of the floor, which doesn't make…

In the bolt shear design check for slip critical bolts using 1 1/4" A325 SC (Class A), the minimum bolt pretension is taken as 81 kips when it should read 71 kips as per AISC table J3.1. Model along with snap shots attached. SC bolts defect.zip

I have got my report, but there is no loading details like dead load, Wind loads and all... In report settings i have added Loadings, but its not showing.... Wt to do???? i want to see other load details. How to get that details?

Hi I wanted to use the ISM feature. But apparently I could not access the software downloads tile on the bentley website to do this. I got this error.(see below) What can I do for this?

Having some problems with RAM Structural Frame: "Some of the Wind Loads for Load Case (every single one of them) may have been missed on diaphragm." How is this solved? If this is a quick fix, please let me know. How do I get the wind loads to generate…

I am using RAM structural systems, is there any way to assign a camber to a specific beam. I want to model the existing framework of a building so I need to include the camber that was there. Thanks.
