Shear Stress Tz null, why?

Hi,

 

I'm checking a lifting beam 4m long - a HEB 320 profile.

The main resulting inner force is the shear - FZ. 

I ran the model, and now i'm checking the results in the Detailed Analysis.

It shows, the sear Fz = 930kN, but no Shear stress Tz. My question is why? 

 

If i go to the stress analysis section and check the TauXZ, the value is corect.

 

Does Tz represent something else?

That indicates that some section's properties are defined as 0. Which section database is this section from? Could you attach the rtd file?

yes, here it is;
the HEB320 section used is from the DIN database

the HEB320 section used is from DIN database (DINpro)

i attached the rtd

yes, i changed the section. I used same HEB320 but from the EuroProfile databse, and Tz is no longer null.

i guess, the one from DIN is missing the shear area value ?

Indeed in this database values of Wy and Wz for HEB sections are 0s. Please use the Euro section database instead.
