Regarding to the Slab Validation Sheet (Slab Design (Direct Design Method)) which uploaded in this link American Concrete design code ACI 318M-2014 (Metric Unit) - RAM | STAAD | ADINA Wiki - RAM | STAAD | ADINA - Bentley CommunitiesHow does RCDC calculate L2 (the clear span of slab transverse to clear span of slab along which moment is calculated)?
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 mmWhere,
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 mmWhere,
8000= c/c span of slab shorter direction
450 = beam width on either side of slab longer directionPlease let me know if you have any questions.

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.
