  • Input & Reported Column Eccentricity

    How can I confirm column eccentricity in RAM SS? Within the Data Echo report it notes in the column table that "values with a + indicate eccentricity plus 1/2 column dimension", then in the table is notes "+100" however these notes in the report do not…

  • Buckling Factor for Simple Pinned Column

    Hi, I used the verification example for the buckling factors for determining the critical buckling loads for a simple column (pinned pinned). However I get different results every time I run them. How do I ensure that the values I get are the…

  • Unable to add column error

    This is my first time using a RAM model and I have run into an error when trying to layout my building. All of my columns go in correctly except for one area where I get the error "unable to add column. column would overlap another column. There is no…

  • RCDC -Column Design as per IS 13920

    Hi, I am unable to use joint check option in ductile column design in RCDC. The option is greyed out. Refer to screenshot below. What could be the possible reason for it. Note: I already have run and designed all the beams in the model. /resized…

  • Change Column Elevation

    Hi, When drawing columns, RAM Concept draw them with an elevation of 0 by default; however, I'm trying to draw column in a slab with an elevation of -12 in. Right now my column go straight through my slab (see picture below). I haven't found any option…

  • Gravity Loads: RAM Concrete vs. RAM Frame

    https://communities.bentley.com/products/ram-staad/f/ram-staad-forum/158562/ram-concrete-vs-frame-forces-for-columns-not-matching I understand that the analysis methods are different between the two modules, however the difference in axial gravity…

  • Can someone explain what the compressible option for column modeling entails? (In Ram Concept)

    Does assigning the compressible feature to the column takes column shortening into account therefore increasing deflections at the column? I have seen that it is usually recommended to apply to models but it would be more helpful to understand why.…

  • BUCKLING ANALYSIS ON A CONCRETE COLUMN

    Hi, Is it possible to perform a buckling analysis on a concrete column in STAAD pro? If so, how is it done? Thanks in advance! Ignacio

    How Can I change the Horizontal position of biaxial columns from the center to the right side, like the below figure? I'm Using Staad pro connect edition.

  • Problem modelling plates on top of beams for elevated steel water tank

    I am trying to model a Elevated steel water tank with bracing for analysis in STAAD.Pro. While modelling the structure I've encountered a problem and would like your help. The problem is: While the beam offset works perfectly for modelling a beam…

  • Column and Wall Rigid Zone

    Hi, I am reading a post about modeling in RAM Concept. One of the questions mentioned rigid zones at columns and walls. See the snapshot below: My question is what stiffness factors one should use for these rigid zones: Thank you.

  • Extracting column loads and LL reduction factors use RAM DA

    I'm trying to extract gravity column loads and live load reduction factors. I tried using the interface IGravityLoads1, with the GetStoryGravityReactOnCol method. But I think I am misunderstanding the input parameter for "lColNum", the column index. It…

  • Testing batch mode column design vs RC interactive designer

    In an effort to find a more efficient way in aggregating the output, I decided to give the RC interactive designer a try and compare it with the batch mode design results. Attached is a screenshot of the result from the batch mode vs the RC designer and…

  • Effective length factor SKY and SKZ parameters in ACI concrete column design

    If the user didn’t assign effective length factor SKY and SKZ parameters in ACI concrete column design, which value does STAAD consider in the column design: 1-The length of the modelled member from node to node or 2-the clear height of the column…

  • Does STAAD design for CONCRETE SPECIAL MOMENT FRAME as per ACI 318M-11 ??

    Hi, 1. Does STAAD take into account the ductile detailing provisions of CHAPTER 21 of ACI 318M-11, while arriving at the reinforcement area and stirrup area ?? 3. If those provisions are available, how does STAAD identify a SMRF or IMRF or OMRF in…

  • Looking for clarification on RAM Steel Column Sign Conventions

    Hello, I'm looking at this article, and would like some clarification: https://communities.bentley.com/products/ram-staad/w/structural_analysis_and_design__wiki/2055/ram-steel-columns-fa The diagram says "minor" and "major" axis moment, however…

  • RE: Ram Steel Column Optimization

    I see. The way trial groups work is that the program sticks to one trial group (one nominal depth) for the whole height. It selects the lightest total column from up to 3 trial groups, so long as the design passes the code check at all stories. That's…

  • Bottom and top of column member forces do not match

    I've built a 3 story RAM SS model with steel columns pinned at the base, and concrete piers (modeled as concrete columns) pinned at the top. When running a report on the member forces of each, the loads at the bottom of one do not match with the loads…

  • RE: Does RAM Concrete check for ACI 21.13: Members not designated as part of the SFR system

    See Section 4.8.4 in the RAM Concrete Column Manual for the sections of 21.13 that are implemented in the program. Induced moments and shears are not calculated by the program, so the program follows ACI 318-11 21.13.4 and not 21.13.2 or 21.13.3 when…
