Project 2_Design & Analysis of a Hostel building at Guwahati, Assam
Open the ETABS software and click on the New Model to create a new File.
Select metric units and relevant IS codes to proceed.
Choosing the Grid system and storey details with New Model Quick Templates custom grid spacing and custom story data.

Selecting Floor Loads and Loads from Above and selecting all the load combinations
Design of Foundation using SAFE
Import the file to SAFE software.
First step is to define Material and Section property
Defining Section properties
Defining the column as a stiff slab of 800 mm thickness
Defining the Pile cap as a mat slab of 800 mm thickness
Defining the pile cap as a mat slab of 800 mm thickness
Defining Point Spring property of the Piles:
Defining the Tie of beam of size (450 X 800) mm and (600 X 800) mm for interconnecting the columns at foundation level.
Now drawing the Pile caps – Here I have used the 3 different sizes of Pile caps i.e., (3X3) m, (3X2.5) m, (4.5X2.5) m. Later Drawing the Piles, columns and Tie beams.
Checking Punching shear Ratio:
Punching shear ratios are less than 1, hence safe.
Shell Forces on the Pile caps.
RESULT:
G+3 Hostel building is designed and analysed in ETABS.
The foundation is designed and analysed in SAFE.
