Dear Experts, I got a different UR result between assigning UNL and not assigning UNL and it give me a confusion which model is true. Hereby I attached separate model with UNL parameter and no UNL parameter. Which model is more accurate to design…

I'm trying to understand the function of "parameter" sets in STAAD. From what I see, you would use different parameter sets so that in post-processing you can change which parameter set that you want to see results for. Is that correct? Can you help…

Hello, I have defined multiple parameters in order to check different load combinations for different groups as shown in the portion of the input file I pasted below. LOAD LIST 1101 TO 1104 1201 TO 1204 1301 TO 1320 1401 TO 1412 1501 TO 1504 - 1601…

I am trying to learn the behaviour of LZ and LY parameters of CODE AISC UNIFIED 2016. I notice that KLR is not changing accordingly with rx and ry. MC6X18: rx = 60.2 (for Ly); ry = 26.7 (for Lz) STAAD results: when Lz = 1.0m → KLR = 37.34; L z…

Dear Pros, I'm designing Steel structure with Eurocode by using automatic default parameter values by Staad except Kz. But I do not make sure that these default valus is correct or not? Otherwise, How can I export (or show) theses default parameter…
