: Checks for adequate slab depth and determines the required area of tension reinforcement ( Astcap A sub s t end-sub ) to resist bending moments.
This is the primary code for load calculation. It dictates the magnitude and nature of live loads (vehicles) and impact factors. A design sheet must account for: Box Culvert Design Excel Sheet As Per Irc
