Project 2_Design & Analysis of a Hostel building at Guwahati, Assam

AIM: To design and analyse G+3 hostel building in Etabs and foundation in CSI SAFE.

INTRODUCTION:

1. The procedure for the analysis and design of a given building will depend on the type of building, no. of storeys, building's complexity and many more.
2. The procedure for structural design will involve many steps which will depend on the type of building and also in its complexity and time available for structural design.
3. Further, before starting the structural design, the following information of data are required.

• A set of architectural drawings;
• Soil Investigation report (SIR);
• Location of the place or city in order to decide on wind and seismic loadings;
• Data for lifts, water tank capacities on top, special roof features or loadings.

PROCEDURE:

• Select design parameters
• Select Storey grid and heights

• Add material property

• Add frame, column and slab properties

• Add load cases

• Add load combinations

• Add modal mass source

• Add diphagrm

• See the base values

• See the modal participation mass ratio

In the analysis

It is found

UX= 85%

UY= 83%

UZ= 83%

Hence ok

• Check bending moment & shear force digram

• The design of the member is checked

• Check the beam reinforcement for plinth level

• Check the column reinforcement

• Now export the modal to safe software for foundation design
• open safe software
• import the file
• we need to export the model by taking all the loads from the upper stories
• view the loads taken from etabs in safe software
• Add material property

• Add Slab section property for pile, pile cap and column

• Add pile, pile cap and column according to its size given as per the question

• Add soil subgrade property

• Add pile cap spring

• View loads

• View punching shear
• We need punching shear equals to .8 or to .9 it should be less than one

• Now run the analysis to get the reinforcement details of the pile cap and pile
• Check As per IS:2911 part 1 is considered for the design and construction of pile foundation

• Pile and Pile cap reinforcement detailing

RESULT:

• Etabs model for either side of two block is been designed
• Foundation details for the pile and pile cap is been provided
• Column reinforcement is been provided
• beam reinforcement is been provided
• Etabs and Safe files of project report is been provided
