Being a relatively new PVElite user I am interested in learning more about how this rigging analysis works.

Thanks,

Todd

Hello Todd,

There is a write up on the rigging analysis in the January 2001's newsletter. To access the newsletters from the COADE home page go to Support -> Newsletters.

Some of the screen have changed since then but the basic procedure is the same.

Let us know if you have more questions.

Hello Todd

During this year, the rigging analysis was re-written to increase accuracy. Please let me know if you need more information.

Dear Ray/Mandeep,

I have been asked by my chief to compare rigging analysis results with hand calcs (we have recently acquired PVelite for this purpose).
After performing hand calcs (case 1. All loads as uniformly distributed loads (UDL), case 2: UDLs+concentrated loads):
1. My reaction forces at lifting and tailing come within acceptable margin than those reported by PVElite.
2. The Maximum bending stress location was also predicted correctly.
3. However and here's my question, my bending stresses are way higher than those predicted by PVelite (including the max bending stress).
Please note I'm also considering an impact factor of 1.5 in my hand calcs as well as the software.

For bending stress, I'm using
Sigmab=M.y/I (M=Bending moment)
I=pi/4(Ro^2-Ri^2)
y=ID/2

Please provide information on how PVElite calculates the bending stresses.
I believe there may be certain assumptions in your case (or mine) which may be causing the difference.

Thank you in advance for your assistance.

Regards,

Suhas.
