  • Knee brace gusset to beam/ column connection eccentricity due to workline not coinciding with weld centre

    We have encountered a problem while performing checks in vertical brace knee brace. The software does not allow us to enter the values of Xleft and Xright, which represent the eccentricity from connection centre to workline. As a result, the calculation…

  • Extract beam maximum dead and live loads

    Hi, I am trying to export a csv or excel file where I can see the maximum Dead and Live/Roof live load moments in each beam. I need to obtain them unfactored to post-process them in excel. The table would simply have the beam label, Md and ML. I've been…

  • RAM Elements Wall on top of a Beam - Moment

    Is this post from 2015 still the best way to model a wall/shell element on top of a beam ignoring the shear transfer between them? I have a situation similar to the image below and would like to get a moment closer to the simple span moment of 903 kp…

  • Disproportionate moments results

    Hello, I ran the analysis of a lightly loaded two-sorey building on staad and results I got is disproportionately large. The first attached image shows the moment about the z axis (MZ) which appears too large for the screen to display and for the…

  • Beam to column flange connection with Haunch Checks

    When applying compression force only in a beam to column moment connection, RAM applies the complete compression force to the flange of the haunch only. Moreover, it considers the flange as a slender plate not welded to the web. My question is: 1…

  • RAM SS Gravity Column Design

    The gravity column design interaction equation H1-1a in RAM SS does not account for the Mux/(0.9Mnx) in the unity equation. Why is that ?

  • Load combination for Deflection

    Hey, Can anyone please tell me what load combination does RAM SS use to determine deflections? Is it DL+LL or 1.2DL +1.6LL? Also, where can I check that ? Thank you

  • 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…

  • RAM Footing tension from moment from bottom of footing

    Hi, I have a building with moment frames. All lateral columns are fixed at the bottom and the pile caps keep failing with tension in the piles. I pinned the columns at the bottom, thinking it will make it worse, and it actually all worked. So the tension…

  • OpenSTAAD - Switched Bending Moment Forces Output?

    I was trying to update an old OpenSTAAD excel macro so that it can run on the latest STAAD.Pro CONNECT edition. While I was trying to extract maximum bending moment member forces I found that the syntax that should've extract max moment comes back with…

  • RAM Structural System: Live load reduction

    Does RAM SS consider all the stories where I have the unreduced live load for the calculation of the tributary area that is considered for the live load reduction? Design per ASCE 7-10.

  • RAM Concept Line load

    Hey I'm trying to apply a moment line load (kips). I want to how does the program interpret it ? Or can I just apply a point moment (kip-ft)? Whats the difference between those two? Also, the moment I have is for the basement wall that is 220' long…

  • RAM Concept Slab Moments

    How does RAM concept calculate the moments that you see on the moment plot, in slabs? What procedure does it use? And is it code based or FEM based? Thanks

  • RAM Frame- Steel Moment Frame Joint Stiffness

    How does RAM frame handle joint stiffness reduction when analyzing a steel moment frame? I have a structure with steel moment frames and would like to explore the option of using flexible moment connections. What is the process of reducing joint stiffness…
