Hasan / SeismoSoft Team,

I deleted all permanent loads since the program was having trouble applying them to the structure during the analysis. I just wanted to see what would happen with incremental loads only. When I try to run with no permanent loads, I get the following in a message box:

"No solution (C:\Users\santon\Documents\My Programs\SeismoStruct_Common\Exe-Analysis-12SectionAnalysis.pas, line 1596)"

I believe that this was the message Hasan was getting earlier on in his attempts to model this structure.

I wonder if there is some anomalous input in one of the sections somewhere which is preventing an analysis of that section from properly completing, which could also affect the application of permanent loads? Or of there is something in the subject line of Pascal code which causes infrmDBPH elements from being processed properly?

Just a thought. Press on.

Just to see what would happen:

1. I changed all elements to infrmFB
2. I removed the incremental displacement (wonder why both incremental displacements and incremental loads were being applied simultaneously)
3. The permanent loading was applied fine with no errors.
4. There is a high degree of nonlinearity experienced at load factors as low as 0.04 to 0.05.

The above makes me wonder if:

(1) The structure is simply not robust enough for the load to which you are trying to subject it.
(2) Is there some peculiarity in the infrmDBPH element?

Just more thoughts.

Hello Hasan,

Can you please send us the model at support@seismosoft.com, so that we can have a look?
Thank you,
