Inclined Length of One Step

The inclined length of one step is calculated using the Pythagorean theorem:

= 340mm

Step Area Calculation

Plan Area of One-Step

Inclined Area of One-Step

Total Step Area

 Total area = 0.024 + 0.054 = 0.075mm2

Dead Load (D.L.) Calculation

Assumed Concrete Density 

Concrete density is assumed as: 25 kN/m^3

Dead Load of Step Section for 1m Width and 300mm Plan Length

Dead Load Per Square Meter on Plan Area

Live Load (L.L.) Consideration

Assumed Live Load for Residential Building

Total Load on Staircase

Factored Load Calculation

Factored Load Using Load Factor (1.5)

Design Load Consideration

Staircase Width Assumption

Width of Staircase = 1m

Final Factored Load Calculation

Design Load Value

This analysis provides an essential calculation framework for staircase load design, ensuring safety and structural integrity.
