Design of beam supported by a panel

[Μηχανικος]

Hi,

I am trying to design a beam that is supported by a panel (shear wall) on one end and by a bar (column) on the other end. see picture below.

When i import the beam in the Provided reinforcement module, Robot does not recognise the wall as a support and considers that the beam is a cantilever supported only by the column on one side, see picture below. How can i solve this?

could this have implications on the anlaysis?

 

When i import the beam in the design module it gives me the option to select the supports but the support given there is a node on the slab.

Mark both check boxes during the import and adjust the width of the wall support if needed inside the RC Beam design module.

I did try that before posting and something strange happened, the design module brought up the design for a foundation, however now irs working great.

I have one more issue regarding the same subject.

Now i am trying to import 3 beams into the provided reinf. module.

As you can see from the picture below, beam No.1 is separated from the other two beams by a panel (wall), while the other two beams No.2 & 3 are continuous.

At the supports tap i have ticked all the members, and i even tried different combinations (see below).

However the module only imports beams No. 2 & 3 together in the same module and imports beam No.1 on its own in another module. Any ideas would be greatly appreciated.

The easiest would be to replace a wall with a column (bar element).

Hi,
I have problems adjusting the support width as i did not get the principle of it from the explanatory video. 
This is the beam i'm trying to design in the RC Beams module with those walls as supports.
The beam with the walls and span dimensionsafter importing the beam to the moduleAfter adjusting the walls dimensionsAfter adjusting the offsets
After adjusting the support width for both sides, the beams span shrinks. I tried to adjust the offsets as shown in the video, i got the correct beam span however the beam connected to it (shown in previous pictures) disappeared and the moment diagrams shifted as if the beam itself was stretched.
These are the offsets used:

Any Help??

Thanks

Hi @Artur.Kosakowski

i havent got any answer yet.

Hi @Anonymous

I wish I could answer everybody in no time but it is not doable 

Could you attach the model?

[Anonymous]

Thank you @Artur.Kosakowski for your continuous support.
i've attached a model with a lot of examples of beams supported on walls that need width editing when exported to rc beam module.

Moreover, i've noticed that the moments and shear differ between the model and the rc beam module. If you could check it out aswell or is there any explanation why.


Regards,
Johnny

Hi @Anonymous

Which beam (bar number) is it and which load case or combination is the diagram for?

[Anonymous]

The bar number is 106 and for combination 4: 1.2D + 1.6L

Hi @Anonymous

As Robot assumes end nodes of a beam in a model being in the centers of te supports you need to either:

- define this beam as a 'longer' one till the middle of the'width' of the support you want to decide on during reinforcement design

or

- change the support type to masonry 

For the maximal moment in the span it is the accuracy of the number of points the values are taken from
