👉Detailed Explanation Without Formulas

1. Dead Loads (D)

Dead loads are the permanent weights of structural components and finishes.
- Slab Load: Determined by slab thickness and concrete density, giving about 3.6 kN/m².
- Beam Load: Typical beam dimensions contribute around 4.3 kN per meter length.
- Column Load: Each storey column adds approximately 19.2 kN.
- Wall Load: Masonry walls per storey add about 11.5 kN per meter length.
Together with finishes, the total typical floor dead load is about 8.26 kN/m².

2. Live Loads (L)

Live loads depend on occupancy type.
- Residential floors: about 1.9 kN/m²
- Office floors: about 2.4 kN/m²
- Roof: about 1.0 kN/m²
These values follow ASCE 7‑16 standards.

3. Seismic Load (E)

Seismic design considers site class, spectral accelerations, and building height.
- Site Class D with moderate seismic parameters.
- Fundamental period of vibration is about 1.0 s.
- Base shear coefficient is about 0.037.
Thus, total seismic base shear is a fraction of the building’s seismic weight.

4. Wind Load (W)

Wind loads are based on wind speed, exposure, and pressure coefficients.
- Basic wind speed: 150 m/s.
- Pressure at 2 m height: about 10.6 kN/m².
- Design wind force depends on gust factor, surface coefficients, and exposed area.

5. Factored Load Combinations

Load combinations ensure safety under different scenarios.
- Dead load only.
- Dead plus live load.
- Dead plus wind load.
- Dead plus earthquake load.
For a residential floor, the factored slab load is about 13 kN/m².
