We are working with Leap CONBOX and using it to design a solid concrete slab bridge with mild reinforcing. The output does not include the liveload distribution that was used for the calculations. How is the liveload distribution factor calculated internally? I assume the entire slab width is the design section. My name is Tom Westerman and I can be contacted at 9143-620-9900, twesterman@hgcons.com.
For Slab Cross sections ,The distribution factor is calculated as the reciprocal of the distribution width per LRFD 4.6.2.3 .
Please check the Conbox usermanual for more information.
