In a nutshel, I wonder whether the function...
openSTAADObj.Geometry.GetNodeList
...is working fine, in anybody's experience. In my case, with the VBA code given in above post, it is giving error, saying:
Run-time error '5'
Invalid procedure call or argument
where could I be wrong?

Hi,
I have been trying to extract model details via OpenSTAAD, but it is showing error right from the start (Error 438)... The code is as below
Private Sub CommandButton1_Click()
Dim openSTAADObj As Object
Set openSTAADObj = GetObject(, "StaadPro.OpenSTAAD")...
Hi..
I suppose the following article too might help you in getting some basic idea of Equivalent Lateral Force Analysis, Modal Response Spectrum Analysis, Time History Analysis; and each’s corresponding Non-linear counterpart...
Got it... you inserted a node in a beam that was passing through the diaphragm centre, inserted at that location (as seen in the pic)... it then automatically got added to the diaphragm. On this node, you applied a support... and then assigned a support displacement as a load... [thumbsup2]
With diaphragms, a node automatically appears at it's centre, and one can't himself put the node there to the diaphragm ...
That node is usually no selectable, and so one can't (i suppose) assign a restraint to it.
How did you manage to do it !!??
The same thing I’m also interested in knowing about. All I know is that for a set of PSD curves to be applied on a structure, you have to process and determine another set of Cross-PSD, derived for all combinations of PSD’s, like C-PSD(i,j) derived from PSD(i) and PSD(j) (and obviously not for...
Just model the slab with solid elements, with the outer layers matching the concrete cover, and the layers next to the outer layers not much thicker than the depth required by the two overlaid reinforcement layers (one perpendicular to the other) together.
Also for the layers next to the outer...
I know only SOLID65 having such features... Not sure whether any new element can take 'Concrete' properties. With smeared reinforcement approach, I presume the following will do: cross section of slab shown

Hi..
I presume all that was asked about has been answered. But still I shall put in my view
As far as I know, for rigid diaphragms:
(1) The central node of the diaphragm is located at its centre of mass, where the seismic loads are applied.
(2) Wind load in each direction is to be applied...
Hi..
With BEAM44, one could define element types with end-releases, and use them in cases such as this one. Not sure whether BEAM44 is in active library now, or legacy, or totally discontinued. Maybe you can replace one element at the connection end of the meshed beams with BEAM44.
Key-options...
Not sure, but it is worth a try: Since you’re using links, I’m sure you must have stumbled upon this -- see fig. of screenshots attached (although from ETABS, corresponding ones should be there in SAP2000). Ignore values shown (only meant to show how the curve goes)... still not sure whether...
You may get a break by changing the approach of modelling.
This is because SAP2000, like most other packages, for beam elements, assume the local axis-2 (local y-axis in STAAD) to be perpendicular to the beam axis, lie on the vertical plane passing through the beam, and point upwards.
So...
<< My question is what is SAP2000 doing? >>
SAP2000 doesn't do this, because it hasn't included the 'Dominant mode signage' (DMS) option in it: Probably because Prof. Edward Wilson -- the developer of the original 1973 SAP-IV, and still an associate of the SAP2000 research team -- hasn't yet...
Hi KootK,
Your book suggestion is excellent -- it does go into the fundamentals of RSA.
Hi everyone,
I happened to read a few of the earlier thread (I have joined the forum only recently), and happen to come across the thread on doing RSA with P-Delta effects included...
Presume ROBOT is trying to do Dominant Mode Signage, where, after doing the SRSS/CQC method, gives for each quantity (BM, SF, etc.) the sign obtained for that quantity at that location for a single mode analysis -- the analysis for the Dominant Mode.
Packages with this feature (not SAP2000)...
