I cant figure out how to change the units from metric to english in RC designer. My staad model is in english units but when I open RC design everything is in metric.

How to get the Property Reference Number of Plate element in OPenstaad?
I have written the following code to get the reference no. of the plate elements used in the model, but I could not get the desired results.
I am able to get the thickness of the plate, but I need to get the Plate Reference Number also.
Dim mySTAAD as Object
Dim PlateRefNumber as Integer, Thickness as Double, PlateNumber as Long, plateThkArray(3) as double
.=========
With .Property
.GetPlateThickness PlateNumber, plateThkArray
Thickness = plateThkArray(0) * 1000 '[Working correctly]
PlateRefNumber = mySTAAD.Property.GetPlateThicknessPropertyRefNo(PlateNumber) [Not working] Error: Object does not support this property or method.
End With

Aluminum Design
I am designing aluminium sections using ASD 1994 in Staad Pro. I am using sections from Section Database. After analysing and designing, the only section designed was the Round Tube section, whilst the Rectangular Tube and Angle section could not be designed. And it generates in the output of Aluminum design result as follows. " **IN TABLES 3.3-1 and 3.3-2, NO DATA IS AVAILABLE FOR THE FOLLOWING COMBINATION FOR MEMBER # 1 ** ". Please kindly advised.
Fyi. when I am changing all of the members section to Round Tube section, all was designed properly by Staad Pro.

RE: Anchor Reinforcement in RAM Connection
In RAM Connection Standalone, shear V2 is the major axis shear and is parallel to local axis 2 and shear V3 is the minor axis shear and is parallel to local axis 3. See screen capture below. Shear anchor reinforcement in the major direction increases the shear capacity in the major direction (V2 and Axis 2 below). Shear anchor reinforcement in the major direction increases the shear capacity in the major direction (V3 amd axis 3 below).
In RAM Elements, the orientation of the column defines the local axis of the column. Like RAM Connection Standalone, Vu2 is the major axis sear and is parallel to the local 2 axis and Vu3 is the minor axis shear and is parallel to the local 3 axis. Unlike Standalone, I find that anchor reinforcement in the major direction increases the capacity associated with minor direction (Vu3 and local axis 3), and anchor reinforcement in the minor directions increases the capacity associated with the major direction (Vu2 and local axis 2).
In RAM Structural System, the orientation of the column is associated with the angle in the XY Plane. Similar to RAM Elements, Vmajor shear is major axis shear and the same as V2 in the screen capture above and Vminor is the minor axis shear and the same as V3. Like RAM Elements, I find that anchor reinforcement in the major direction increases the capacity associated with minor direction (Vu3 and local axis 3), and anchor reinforcement in the minor directions increases the capacity associated with the major direction (Vu2 and local axis 2).
You are correct that there is an apparent discrepancy with the anchor reinforcement direction in both RAM Connection for RAM Elements and RAM Structural System. I will discuss this with the development team.

Rodolfo,
Are the tools and anything else in the program in English? If they are, try doing a clean install by following the steps in the link below:

I've installed the English version of RAM Elements. But, whenever there are warnings after running analysis the language used for the 'warnings' is not English. How can this be corrected?

Did you try clicking on the " v " arrow as shown next and then using the " ^ " or the " v " to browse through all of the unit options. Not all options are visible at the same time. It should have English units as seen next.

RE: Anchor Reinforcement in RAM Connection
Thanks, Karl. One clarification: in your reply, you said "Shear anchor reinforcement in the major direction increases the shear capacity in the major direction (V2 and Axis 2 below). Shear anchor reinforcement in the major direction increases the shear capacity in the major direction (V3 amd axis 3 below)." I'm assuming that 2nd statement was about the minor axis and not supposed to repeat the word major.
But in RAM Connection Standalone, I'm seeing behavior where the anchor reinforcing shear bars in the minor axis direction are what has to be increased to reduce overstresses in the Major Axis design check for "Group of Anchors reinforcement in shear". Wouldn't this be exactly opposite of what ACI is showing for anchor reinforcing for shear (screenshot below)? My HSS column is in a longitudinal orientation, so the braces - and the shear - should be on the major axis. Therefore the bars to develop that force on the other side of the failure cone would also need to be aligned with the major axis. Am I missing something here, or is this incorrect behavior in RCSA similar to what you described in RE and RSS?
Thanks,
Jason

RE: Anchor Reinforcement in RAM Connection
Jason, I reran the tests and now see consistent behavior among RAM Connection Standalone, RAM Connection for RAM Elements, and RAM Connection for RAM Structural System. I tested both single column base plates and gusset base plates. I have edited the original post accordingly. I am not sure what happened yesterday, but apologize for the confusion.
In summary:
Shear anchor reinforcement in the major direction increases shear capacity associated with the minor axis.
Shear anchor reinforcement in the minor direction increases shear capacity associated with the major axis.
Regarding your other points and the figure in ACI:
By "in the major direction," we mean parallel to the local 3 axis, which defines the major axis. V3 is minor axis shear and parallel to the local 3 axis.
By "in the minor direction," we mean parallel to the local 2 axis, which defines the minor axis. V2 is major axis shear and parallel to the local 2 axis.
If you interpret "in the _ direction" as above, then the RAM Connection design matches the ACI figure.
Perhaps we should change the wording. Would "Shear Bars Parallel to V3" or "Shear Bars Parallel to Minor Axis" and "Shear Bars Parallel to V2" or "Shear Bars Parallel to Major Axis" be clearer?

RE: How to define the LZ value for the Rafter shown below?
Just bumped into this last question when trying to refer an user to this forum post. If the beam is horizontal, definitely we should use the column to column distance. However for a gable frame like the one in question, I would think, it would be very conservative to consider the LZ as the distance between the columns. Again this is my opinion and practicing engineers, who deal with structures like these on a day to day basis, will be able to offer more insight.

How to define the LZ value for the Rafter shown below?
My first question is, do I need to define the value of LZ for the rafters since they will experience compression?
If so, what should be the correct value for LZ? Is it going to be 12.948m and 11.558m respectively or add 12.948 + 11.558 for the rafters?
By the way, I'm using AISC LRFD as my design code.

LZ Parameter for Rafter of Clear Span Gabled Building
Dear All,
Can anybody suggest what will be the LZ Value for the Rafter of a Clear Span Building. For Example, there is a Clear Span building 30m wide , Slope - 1:10 , Gable at 15m . In this case what will be the LZ Value for Roof Rafter . If possible please provide any relevant thesis for better understanding.

Difference between RAM Elements and Ram Structural System
I recently started working for a small Commercial Structural Design engineering company. I have used RAM Structural System in the past in other companies that I worked for, for design of small to medium size steel buildings, using RAM Steel for floor design of steel joists and steel beams and RAM Frame for lateral.
The company that I work for now has RAM Elements. I have never used RAM Elements. Is RAM Elements mostly used for stand-alone beam and column design?
My basic question is what would be the best Bentley/RAM Product for design of gravity and lateral design of a 1-2 story steel commercial building with steel joist and beams supported on HSS columns? Appreciate if someone could share their views.
Thanks.
