How does RCDC calculate L2 in the 2-way slab design?

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.

I'm appreciated for your help.

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

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.
