👉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.
🧱 Engineering Insight
This sheet integrates ACI 318‑19 and ASCE 7‑16 provisions, serving as a compact reference for engineers to validate design loads before structural analysis. It balances dead, live, seismic, and wind effects to ensure safety and compliance.

👉Column Load Calculation
🚧A column is a vertical structural member that transfers loads from slabs, beams, and walls down to the foundation.
📎Proper column load calculation is essential for safe and economical structural design.
🔹 Types of Loads on a Column
1. Dead Load (DL)
Permanent load of the structure.
Includes slab weight, beam weight, walls, finishes, and structural elements.
2. Live Load (LL)
Temporary or movable loads.
Includes people, furniture, equipment, vehicles, etc.
3. Self Weight (SW)
Weight of the column itself.
Depends on column dimensions and material density.
🔹 Column Load Formula
Total Column Load = DL + LL + SW
Where:
DL = Dead Load (kN)
LL = Live Load (kN)
SW = Self Weight of Column (kN)
🔹 Example Calculation
Given:
Dead Load (DL) = 200 kN
Live Load (LL) = 150 kN
Self Weight (SW) = 20 kN
Calculation:
Total Load = 200 + 150 + 20
Total Column Load = 370 kN
🔹 Important Notes
✅ Consider all load sources acting on the structure.
✅ Use accurate dimensions and material densities.
✅ Follow relevant IS Codes for design and safety.
✅ Ensure proper load transfer from superstructure to foundation.
✅ Check load combinations for ultimate and serviceability conditions.
📚 Engineering Tip
A column does not carry only its own weight.
It receives loads from slabs, beams, walls, and upper floors, then safely transfers them to the footing and soil.
