Foundation design using SAFE
PROCEDURE
QUESTION 1
1. Define material properties
2. Define Slab properties
3. Define Load pattern
4. Define Soil Subgrade modulus
5. Assign Point load
6. Assign load combinations
7. Check design preferences (min cover 50mm)
8. Run analysis and design
RESULT
The foundation design is done
QUESTION 2
AIM
Model and Design the pile cap using given Data in Safe
DATA PROVIDED
Axial load = 1175KN
Length of pile = 16m
Dia. of pile = 500mm
Pile capacity = 200KN
No. of piles = 1175/200 = 5.875 = Assume 8 piles
Area of each pile = `Pi d^2/4` = 196349.5mm^2
E=5000`sqrtFck`= 25000
Spring constant = 306.79KN/mm
Spacing of pile = 1250
Edge spaceing = 500mm
Length = 5250mm, width= 2750mm
STEPS
- An open new project with IS 456: 2000 recommendation
- Define the materials
- Define the slab
- Define the soul subgrade
- Define the load
- Draw the piles
Using reference point, draw: piles, pile cap and column
- Assign the following
- Run the analysis
- Check the pinching shear
- Draw the design strips
RESULT
The following design is done with the reference to IS 2911 and SP34
