One way spanning slab

[Tmanzz]

Can someone kindly assist with the attached model?

I am trying to get the slab to span in just one way but it appears to be distributing the loads in 2 ways.

Please advise the best way to do this.

It has been modelled as a plate.

Thank you

Hello Tmanzz,

You can set the reinforcement in one way, see below:

Hi @DennisVDijk 

Thanks for that explanation.

Unfortunately can't open the attachment. Not sure why.

Can you resend as a Robot file please?

Hello,

I Attached a new ZIP file. I is not possible to attach RTD file.

Hi @DennisVDijk 

Thanks for that. I have been able to open it.

As a one-way spanning slab is it possible not to have any moment in the YY direction?

Ideally I want all the moment to be along the long span xx.

This is a precast slab spanning in the longer direction.

@Tmanzz,

If You use shell than there will always be moments perpendicular to the main direction, but with orthotropic you can reduce this:

If you don't want the benefit of a shell model you should model it as a beam.

results:

model attached.

TIP: mesh-size equal to the thickness of the slab 😉
