• Repeat load command giving wrong result

    Hi, I was trying to do P-delta analysis in STAAD. However, I noticed that giving REPEAT LOAD command instead of adding load combinations is giving me wrong results. For instance, the deflection at a particular node is 130mm in seismic X direction…

  • SFA User Defined Load Combinations

    Hi, I want to define my own set of load combinations. How do I add more load combinations?

  • OpenSTAAD | OSLoadUI::CreateLoadEnvelop is not working properly

    I'm using STAAD.Pro Script Editor and OpenSTAAD library to generate a structural model. Unfortunately,t he OpenSTAAD function (OSLoadUI::CreateLoadEnvelop) that should allow creating load envelopes is not working properly. Question: Is Bentley Software…

  • SLAB LOAD COMBINATIONS ARE NOT LOADED IN RCDC

    Hello, I have modeled a wall that rests on a slab on four beams and when going to the RCDC I do not see the option of being able to load the slab with the load combination created in STAAD, which is, by the way: All I see in RCDC is this: Instead, as…

  • Wrong Loading Combination for Beam Optimization

    I am working on a two story steel building and am experiencing issues with the beam optimization. RAM is currently using a loading combination for some beams, displayed below, that is not the maximum loading so the beams are designed too small. Instead…

  • FAIL TO GENERATE A LOAD COMBINATION - DEFINE COMBINATION

    Hello, I am in trouble trying to generate a load combination between self-weight loads of a structure and moving loads on that same structure. When I select the option "add new load cases > define combination", this is all I see: As can be seen…

  • TENSION MEMBER ONLY (RESPONSE SPECTRUM),

    is it possible to analyze with Staad for REPEAT LOAD as it is not possible to do with Load Combination?

  • Negative Load Case vs Negative Load Combination

    Dear Colleagues, Say if I have to apply wind on all the four sides (+x / +z / -x / -z) of an irregular structure/geometry, is it okay to consider only 2 positive cases (+x / +z) as Basic Load Case and generate 4 load combinations with 2 positive and…

  • RAM SS Orthogonal Effect with Redundancy Factor

    Hi, I have a building with two orthogonal braced frame intersecting, which makes one of the column forms both lateral system in the orthogonal direction. Per ASCE 7-10, section 12.5.3.a, Orthogonal Combination Procedure shall apply (see figure 1 below…

  • Seismic load with springs- Repeat load case

    i am currently designing an irrigation channel which requires application of compression springs along with seismic loads. i have defined seismic loads first (load no. 4). i have used repeat load cases to combine all the loads. In summary, i can see…

  • Load combination as per IS456 & IS1893

    Dear sir, After defining load combination; I have to developed Envelop. for that which combination I use for Serviceability& which for Strength. please confirm me load combination for both.

  • RAM Concept - Design Envelope

    How can I determine which load combination relates to a specific design envelope?

  • RE: Differences in Types of Load Combinations

    More on the different load combination types can be found on the web page below: https://communities.bentley.com/products/structural/structural_analysis___design/w/structural_analysis_and_design__wiki/3157 "RC-Design" combinations are used only…

  • RE: Auto load combination for General Category as per AISC

    The AISC green book referred to ANSI A58.1 - MINIMUM DESIGN LOADS FOR BUILDINGS AND OTHER STRUCTURES for load combinations. Subsequent versions of the AISC codes started referring the ASCE7 for these combinations. So if you look at the ASD load combinations…

  • RE: Pdelta Analysis / Perform Analysis Command

    Hi DSANJU, Thank you for your reply. Based on your explanation, the correct on should be like this? Please your confirmation. Thanks a lot. ********************************************************** DEFINE IBC 2006 ACCIDENTAL SS 1 S1 0.37…

  • Pdelta Analysis / Perform Analysis Command

    Hello everyone, Q1: I want to know whether this format is already correct or not? Q2: After we define the seismic definition, then we start to add Load Case of seismic first.. Does the PDELTA ANALYSIS command should be written in this load case…

  • Load Combination

    Dear members, Can you help me in making difference between Repeat Load, Load combination and Reference load. What is the appropriate position of assigning these loads. Furthermore, how can we assign the negative sign in load combination? …

  • Notional Loads on Load Combinations

    Hi, I have to take into account the NOTIONAL LOADS into my Analysis so I need to include their effects in the Load Combinations, so the question is: Which is the correct way to state them?, 1) As a Basic Load, and then called them from Load Combinations…
