Hello all: I am new to frame3dd. I am able to set up a simple case of a beam and compute shear forces and bending moments. But, I am not able to see stress results: shear stress or bending stress. How I can do that? Héctor |

I am not able to run the program. Are there missing files in the download? When I download the program this is what I get: An application named frame_ed An application named frame3d One text file labeled frG A folder titled x86 that appears to have the ansicon application. I do not receive any examples or other supporting documentation. When I click on frame3d nothing happens. When I click on frame_ed a window opens for a program labeled FrameED - Frame Input Generator v3.3. I can input nodes and members in this program and view the structural shape. If I then click on an icon labeled "Run Frame Analysis" I am directed to select a .txt file and run an analysis. I created a text file that matches all of the input data for the structure members and shape, and added a point load to the structure in the text file. When I click on this .txt file I get this in the window: FRAME version: 3 January 2002, GPL Copyright (C) 1992-2002, Henri P. Gavin http://www.duke.edu/~hpgavin/frame/ This is free software with ABSOLUTELY NO WARRANTY. For details, see http://www.fsf.org/copyleft/gpl.html There is no output file and nothing seems to run. I think I am attempting to run the old version of the program, when I should be running the app labeled "frame3d," but that application doesn't do anything. I have a PC with Windows, and not sure what to do next. Are there missing files that are not being downloaded? (The Frame3d program is only 158 KB). Thanks for your help - Jean Gajary, PE Structural Engineer jg...@ho...<mailto:jg...@ho...> 215-292-4426 |

The program appears to do the structural analysis first and then the modal analysis. However, in my case, the dynamic behavior influences the load vector, i.c. a factor dependent on eigenfrequencies. I have gravity loads combined with wind loads. Only the wind loads are affected by the dynamic factor. So I have to know the eigenfrequencies before setting up the load vector. Can I do that by simply altering the sequence of certain code blocks, i.e. by moving the modal analysis block to the front? |

Hello, I am a software developper,and i want to make a genetic algorithm for structure evaluation and validation. I did not manage to get formulae for (1)Torsionnal Moment of inertia for angle bar,Jxx (2)Shear area of angle bar for Asx ,Asy How can i approximate/calculate this for varying angle bar sections? Thank you, Jeet |

I thing bending moment should be:

Where is the problem ?
Thanks, if you will have time for answer.

Hey, I couldn't find a template available for using a .csv instead of a .3dd, so I adapted the original template. I'm posting this to hopefully stop others from having to re-invent the wheel. It was created with comma separators and " text delimiters. Cheers, Simon |

Hey all--
I'm helping a friend build a single helix spiral stairway and I've used
Frame3dd to help with the structural analysis. By way of introduction,
I'm an electrical engineer by day and it's been a great many years (beers)
since I had statics in college. Never had any strength of materials.
Frame3dd is an excellent bit of software. I had no problems getting
my design into Frame3dd and the results I've gotten out are promising.
One load case is for three, 300# people standing in the middle of the
run with a 3x safety factor. The stringer at this point of load sees
a displacement of (all units are in inches and pounds):
X-dsp Y-dsp Z-dsp X-rot Y-rot Z-rot
-0.153096 -0.055226 -0.152578 -0.000050 -0.001968 0.005960
Combining X,Y,Z displacement into a single displacement yields a total
of 0.225" which is nothing for 2700# of blubber.
The member connected to the above joint sees the following end loads.
Nx Vy Vz Txx Myy Mzz
510.072c -426.820 -120.534 -15590.949 25120.657 -8492.681
-510.072c 426.820 142.663 15590.949 -24247.803 5624.725
At this point, I need to make sure these numbers stay below the allowable
stress for the beam. The beam associated with the above example is a
8x3 rectangular steel tube with 3/16" wall and 6.7" long. I've got all
sorts of good info about that piece of steel.
weight/foot 13.25 lbs
b/f 14.2
h/f 43.0
Xc 3.63 in^2 cross sectional area
Ix 27.8 in^4
Sx 6.94 in^3
rx 2.77 in
Zx 8.87 in^3
Iy 5.94 in^4
Sy 3.96 in^3
ry 1.28 in
Zy 4.43 in^3
J 16.2 in^4 torsional stiffness constant
C 7.68 in^3 torsional shear constant
Changing XYZ to get the load system to match the materials system:
Nz Vx Vy Tzz Mxx Myy
510.072c -426.820 -120.534 -15590.949 25120.657 -8492.681
-510.072c 426.820 142.663 15590.949 -24247.803 5624.725
So, given all the above info, how do I calculate the actual stress in
this stinking 7" long chunk of steel?
I have a feeling that this is an easy question for a trained professional.
Speaking of which, we will be running the design past a *real*
PE/structural engineer, but I'd like to know how to solve this problem
myself. Besides, it's always good to get independent confirmation.
For fun, I've attached an image from gnuplot showing the design (presuming
the list server will pass the attachment).
Thanks in advance.

Dear Henri, IMO modeling elastic soil with elastic frame elements is appropriate in most cases. But from a post processing point of view I find to be easier to deal with one frame element per foundation beam, hence my suggestion to add such kind of element. I might also volunteer to add code to Frame3DD, but not in the close future: I guess I'll have no significant spare time (paternity).

Dear Walgri, Thanks for your thoughts and for your suggestions. For elastic soil, would it be sufficiently accurate to model the soil with elastic frame elements? The addition of new element types is clearly a good direction for Frame3DD, and given the time I may undertake this. For the time being, I am not aware of new development in this direction.

Thank you very much for your answer (and for updating the online docs too). Frame3dd is getting to be a nice workhorse ! Also, a nice addition could be having frame elements on elastic soil, and catenary cable elements.

Walgri -
Yes, you may specify any number of trapezoidal loads on the same member in
the same loading condition.

Subject: Multiple loads on a member or node
Hello,
I would like to know if it is safe to declare more than a load of the
same type in the same loading condition, on one member or node. I mean
two or more trapezoidal loads onte the same member in the same loading
condition.
Thanks,
