MEd Peak smoothing

Hello, according to EN 1992-1-1, chapter 5.3.2.2. the peak of bending moment over the support can be reduced on delta MEd in multi span beam.
And I found few words about this in manual BEAM, saying that smoothing might be attached by command CTRL if the boundary conditions were set up previously. Also there is a need to create a design element along the structural line through DECREATOR.

I modeled simple beam with 3 supports in Revit, and adjusted a code by teddy manually in stage of “Linear Analyse” and added all the following steps that were mentioned in manual.
Calculation is working, no warning or errors. And new boundary conditions are visible ( faces of the hinged column), but there is no smoothing of the peak in graphic. Seems like commands doesn’t work.

Maybe I wrote it in a wrong order and it’s overwrites? or it’s not possible to do this kind of manipulations having Revit as pre-processor?

Share your experience please how do you perform Peak Smoothing in SOFiSTiK for future reinforcement?

Thank you a lot! Any information would help me a lot !

Hello Mr Shatalin

The SOFiSTiK Analysis + Design Tool can smoothen the moment over the supports automatically.
Therefor you have to run the function: SOFiSTiK Analysis > Design > Beam

Within the SOFiSTiK: Beam Design dialogue you have to define the support conditions and the design locations. In addition you have to activate the function “Smoothen moment over supports”.


After the calculation you can see the reduced bending moments within the Report Browser.


If you want to know how the corresponding TEDDY input has to be, you can open the file beam_*.dat within the project folder. There you can see the generated CADINP input for the programs DECREATOR and BEAM.

Hello,

This is very interesting. Would it be possible to attach that “beam_*.dat” for people who only use TEDDY and don’t have any idea of SSD?

Thanks and regards.
