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

<t>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 ...

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.

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

<t>After the portal3D, I have analyzed my structure of thesis (pushover analisis) and i have a recurrent error. In the "Permanent Loading" phase appears written:<br/>
"LF= 0.00000,LF_incr= (Iter: 1 => fbd_Inv)... Unable to apply the entire permanent load. Analysis terminated".<br/>
<br/>
I'm ...

<t>Thanks very much Federica,<br/>

so... i have had convergence problems about portal2d... analyzing a portal3d,instead, i obtained results expected .<br/>
I noted that the two ways have differents results .<br/>
The first, with using con_frp, it's better about the increase of only ...

<t>hi seismosoft support,<br/>
thanks for the answer. I have read the forum and i understood that there are two ways to modelling structures with frp.<br/>
1)the model con-frp to be using the existing sections for concrete cover and section core.<br/>
2)using a new cross-section to add to existing ...

Hi,
where the thickness of the FRP is included? and how i can to model a beam with frp on 3 sides(bottom side and left and right sides for a part of the hight)?
if the answer is in past posts, can you show me it with a link?
thanks

hello, i have 2 question about convergence of a general analysis:
1)what does "fbd_inv" means, in the running analysis?
2)which parameter should be changed to not have the fbd_inv ?

hello, the way of numbering the nodes and elements affects the convergence analysis pushover?
