Foundation Design using SAFE

1. Model the isolated footing provided in week 11 challenge on SAFE. Analyze and design it to verify the size, depth and steel provided as per calculations.

2. A column of size 600x600 carrying an unfactored gravity load (DL+LL) of 1175 KN is to be supported on pile cap, which ultimately transfers load to the piles underneath. Piles of 16 metres length and 500 mm diameter are to be used. Each pile has a load carrying capacity of 200 KN. Model, analyse and design the pile cap on SAFE to evaluate the following:

• Pile group to be used
• Depth of pile cap
• Longitudinal steel on top and bottom face in both directions

AIM:

To analysis the model of week 11 challenge in safe software and check for failure

Calculation:

Factored load = 2000 KN

Unfactored load = 2000/1.5

= 1333

Overall load = Dead load + Live load

assume Live load = Total load /2

= 1333/2

= 666.7 KN

similarly Dead load = 666.7 KN

now,

Subgrade modulus for soil = SBC*Ultimatefactor/ maximum settlement

= 150*3/0.05

= 9000 KN/m^3

Fy = 500 N/mm^2

Fu = 575 N/mm^2

Fck = 25 KN/mm^2
