error during analisis

[sarah]

very important question!
it's the first time i use this program:
when the processor starts i find this writ:
"Unable to apply the entire permanent load. Analysis terminated"

why?

thanks

Hi Sarah,
what kind of analysis do you doing?
It's possible that loads are very large!

[sarah]

Hi paky!
I made a static analysis of an existing bridge, so the loads are real!
Even if I don't put any kind of permanent load, response of programe is always the same.

Where is the error?
Thanks for the help!

i need to see the input file.
If you want, can you send it me, (paky983@libero.it)
I'm not very expert but i try to solve the problem.

[sarah]

You mean the file .bak?
I will sent immediately.

you are very very kind!!

I think that the problem is the load. In "Element Class" the value to insert in "Mass/lenght" [tonn/m] is the [weight/g] (g=gravity acceleration). The Seismostruct converts automatically the mass in weight ( in project settings - gravity and mass-you must selection" automaticcaly transforms masses to gravity loads")

[sarah]

sorry but I don't understand.
In Element Class I put the mass of the element ( Area * Length * 25kN/m - transformed in tonne ), divided the lenght of the element.

It's wrong?

[paky983]

it's correct...
so, i'm sorry but i don't Know... I had this problem too and i was wronging the loads.

Hi Sarah,
did you solve the problem? If you wish you can send me the model (.spf file) and I can try having a look at it.

Hello everybody,
I believe that i have the same problem mensioned above!!
I m trying to make static pushover analisis!
The analysis is ok when i have con_ma in both section core and cover!! But when i changed the material to con_frp and i assigned it to section core and concrete cover I had the same problem:
"Unable to apply the entire permanent load. Analysis terminated"
why is that happening?

thanks
