Foundation Design using SAFE

AIM: 01

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

PROCESS/ STEPS TO BE FOLLED:

• Open the safe software
• change the IS code and unit system

• Select single footing
• A tabular box will occur
• Change the load size to the size of column
• Change the dead load to the axial load
• Select the thickness of footing according to your knowledge
• Select ok, then a single footing will occur
• Go to define, then add material
• Add m25 as concrete grade

• Add fe500 as grade for rebars

• Go to section properties
• Add MAT and chnage its specification

• Add STIFF and change its specifications

• Go to load pattern and choose DL as 1 and LL as 0

• Go to load combination and choose SLS for servicibility limit state add DL and LL as 1

• Go to load combination and choose ULS for ultimate limit state add DL and LL as 1.5

• Run the analysis

• Check for servicibility, punching shear and deflection

• Also check the reinforcement used

END RESULT:

• Made the model as per previous specifications
• The punching shear is less than 1 it is .98
• The deflection, SBC and RCC is being checked
• ALso the model is been attached

AIM: 02

GIVEN SPECIFICATION,

COLUMN SIZE 600X600

(DL+LL)= 1175KN

PILE LENGTH= 16M

PILE DIA. = 500MM

PILE CAPACITY= 200 KN

MODEL DESIGN AND ANALYSE THE PILE CAP IN SAFE AND CHECK THE PILE GROUP TO BE USED, DEPTH OF PILE CAP, LONGI., TOP AND BOTTOM REINFORCEMENT.

PROCEDURE/STEPS TO BE FOLLOWED:

• Open the safe software
• change the IS code and unit system

• Select single footing
• A tabular box will occur
• Change the load size to the size of column
• Change the dead load to the axial load
• Select the thickness of footing according to your knowledge
• Select ok, then a single footing will occur
• Go to define, then add material
• Add m25 as concrete grade

• Add fe500 as grade for rebars

• Go to section properties
• Add new properties
• Add pile cap and pile500 of M25 grade type matt and thickness of 450
• Add colume of M25 grade type stiff and thickness of 450

• Add circular piles of 500mm dia by selected the piles points made
• And rectangular column of 600x600mm

• Add spring property for all the piles with G= 613.592 as per calculated

• Add gravity unfactored load of 1175kn as per given
• Check and run the anlaysis
• After running the analysis check the punching shear

RESULTS:

• The punching shear is less than one
• The deformation is maximum in the middle and within the range
• The calculatin of reinforcement is being provided
