Bending moment value

Yes understand you

Is it possible that this can affect other degrees of freedom.

 

What im trying to say:

I have made an model whith two shells. 

First plate have thickness t = 25 cm and second plate have thickness t = 100 cm.

Both shells are uniformly loaded with q = 10kN/m2. Along adjoing line My moments are totally different comparing to other software ( in this case i have make comparasion to SAP 2000)

 

Se pic.

Please make sure that you compare the same kind of results.

No Artur

Something is not OK

 

Your pic with global smoothing looks a little good, but values are also different from reality.

try to design reinforcement and you will see what happen.

Im posting two pics with reinforcement areas,

 

In right panel reinforcement area in Y direction is near 42 cm2/m' with both softwares - is OK

But in left panel reinforcement area in robot is Zero, and with other softwares is near 130 cm2/m' 

This is due to almos same moment in both sides but different sections - and its reality.

Why don't you mark the global smoothing (globally averaged design forces) again calculating the reinforcement?

Thanks Artur

 

Now is much better.

 

It is not important the amount of reinforcement in adjoining line of two panels ( especially in left side),

But important ( from software ) is to poin that an amount of reinforcemet should provided due to immediate stiffness change.
