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…
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…
User Tool: Extract Load Combination info/Convert Load Combination to Repeat Load

Description :
This is an excel based OpenSTAAD macro which can either extract load combination load and factor information or convert existing…
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…
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…
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…
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…
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…
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…
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.
More on the different load combination types can be found on the web page below:

"RC-Design" combinations are used only…
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…

Hi DSANJU,
Thank you for your reply.
Based on your explanation, the correct on should be like this?
Please your confirmation.
Thanks a lot.

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…
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? …
