Hi,

Yes. You are correct. the shear transferred to beam is calculated as kN/m and the slab section capacity is also calculated as kN/m.

I wonder how does rcdc calculated shear design part (Vsx,Vsy). Are they calculated in kN/m?

I'm appreciated for your help.

Hi,

Thank you for raising query,

The L2 is calculated based on the Clause 13.6.2.4

In the sample calculation,
L2 for shorter span is calculated as,
8900 / 2 + (450 / 2 + 450 / 2)/2 = 4675 mm
Where,

8900 = c/c span of slab longer direction

450 = beam width on either side of slab longer direction

L2 for Longe rspan is calculated as,
8000/ 2 + (450 / 2 + 450 / 2)/2 = 4225 mm
Where,

8000= c/c span of slab shorter direction

450 = beam width on either side of slab longer direction

Please let me know if you have any questions.
