Staircase Load Calculator

This document provides load calculations for an RC stair case with a total length of 5 meters. It includes the design data, load calculations for each section, and a loading diagram. The load calculations find the dead loads from the weight of the stairs, slabs, and miscellaneous sources, as well as a live load of 5 kN/m. The loading diagram illustrates that the landing slab has a dead load of 5.4 kN/m and live load of 5 kN/m, while the waist slab has dead loads of 6.2 kN/m and the mid-landing slab has loads of 5.4 kN/m and 5 kN/m respectively.
