: Engineers must account for dead loads (self-weight of concrete/steel and finishes) and live loads (typically around 4000N/m² for public or heavily used stairs).
: In reinforced concrete designs, the central stringer is typically designed as a T-beam . The "waist slab" (the flat part under the treads) acts as the flange of the T-beam and must also be designed to resist cantilevered loads from the treads.

: Critical analysis includes generating a Shear Force Diagram (SFD) and Bending Moment Diagram (BMD) to identify peak stress points, ensuring the beam can withstand flexural and shear forces without failure. Design Parameters : Engineers must account for dead loads (self-weight
