load combinations with euro code
how can I create an automatic load combinations with Euro code ?? if not ,, who knows a code has the same combinations in Euro ?? staad can check with Euro code and can't generate load combinations with Euro ??!! Thanks in advance ..
RE: load combinations with euro code
Seismic analysis can be performed only as a Response Spectrum Analysis as per EC3. Static seismic method is not implemented.

Dear Sir,
BCF - web compression buckling check is missing
Dear Admin,
In the RAM connection design report for BCF type of connection, web compression buckling check in accordance to: AISC 360J (eq. 10-8) & DG4 (eq. 3.26) is missing.
This should be check wen both column sides are with moment connections with gravity load @ section with flanges in compression.
Please find attached document.

Bolt tension capacity
Dear Admin,
If use fasteners from BS bolt table and use AISC for connection design, RAM will caculate bolt tension capacity as per BS5950 not AISC. [View:/cfs-file/__key/communityserver-discussions-components-files/5932/Bolts-tension-capacity.pdf:940:0]Is it possible to combine different tables end standards?

RE: Accidental torsional moment vs. natural torsional moment staad
Sye,
Great explanation as usual. That is what I was thinking and thank you for explaining and confirming my thoughts.
I am running both equivalent lateral force procedure and modal spectrum analyses and I can not find a good explanation for the factor assigned after the direction for the spectrum definition.
For example:
The number that comes after the direction "Z" below is default at 1.0. If I run with 1.0 I get unrealistic results. is it supposed to be at 0? and when does it need to be 1.0 or otherwise.

RE: Accidental torsional moment vs. natural torsional moment staad
This is commonly referred to as the direction factor and is basically a factor that is applied on the input spectrum data, in addition to the scale factor. A factor of 1 would mean that the spectrum values you have input, after being multiplied by the SCALE if any, are the actual acceleration values and no further modification is required. You would always use a positive non-zero value and NOT zero. Some design codes like the ASCE require the response spectra, generated based on the code equations, to be further scaled in a certain way ( for example section 12.9.2 of ASCE 7-10). If such modifications are required, you may account for these by using the direction factor. For example to scale the spectrum data as indicated in 12.9.2 you may use a direction factor of Ie/R. Another thing that you need to ensure is that, the value you are using for SCALE is consistent with your input units. For example, if the spectra is in terms of g and your input unit for length is feet, using 32.2 as SCALE is appropriate but if your input unit for length is inch, the value would be 386.
On a different note, the following page contains a collection of wikis related to response spectrum and you may find it useful too
Accidental torsional moment vs. natural torsional moment staad
What is the fundamental difference between the Accidental torsional moment vs. natural torsional moment in STAAD?
Accidental torsional moments do not need to be considered if the diaphragm is flexible but, what is the natural torsional moment?
Also, how does STAAD handle the inherited torsional moment effects? is it being taken care of into the stiffness matrix itself where loads are being distributed?
Thank You in advance
