👉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.

👉Types of Foundations Used in Buildings
💫Foundations are the structural elements that transfer building loads safely to the supporting soil.
🌟The selection of foundation depends mainly on soil bearing capacity, structural loads, groundwater conditions, column spacing, settlement requirements, and site constraints.
☄A. Shallow Foundations
Generally used when suitable bearing soil is available at a relatively shallow depth.
1. Isolated (Pad) Footing
Supports a single column.
Suitable where soil has adequate bearing capacity.
Common for individual RCC columns.
☄2. Strip (Wall) Footing
A continuous footing provided below a load-bearing wall.
Suitable for uniform soil and moderate wall loads.
Distributes the wall load over a wider soil area.
☄3. Combined Footing
Supports two or more columns on one footing.
Useful when columns are close together or a column is near a property boundary.
Can help reduce eccentric loading.
☄4. Raft (Mat) Foundation
A large reinforced-concrete slab supporting several or all columns/walls.
Useful where soil has low bearing capacity or columns are closely spaced.
Can reduce differential settlement when properly designed.
B. Deep Foundations
Used when adequate bearing strata are not available near the ground surface or when loads/ground conditions require deeper support.
🚧1. Pile Foundation
Consists of piles extending into deeper soil or rock.
Transfers structural loads through end bearing, skin friction, or both.
Suitable for weak surface soils and heavy loads.
🚧2. Well/Caisson Foundation
A large hollow foundation sunk into the ground.
Commonly used for heavy structures and foundations subjected to scour or water-related conditions, particularly bridge works.
🚥Important Note
The foundation type should not be selected from soil type alone.
A geotechnical investigation and structural design are normally required to determine the appropriate foundation size, depth, reinforcement, allowable bearing pressure, and settlement criteria.
Local building codes and site conditions must also be considered.
