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

Aim- to model,analyse and design the architectural G+3 building located in Guwahati,Assam and producing result of

• Etabs model for two blocks on either side of the expansion gap
• Foundation details illustrating the pile and pile cap reinforcement.
• Tie beams details connecting the pile caps.
• Coulmn reinforcement
• Framing plan for typical floor
• Beam reinforcements for grounda floor.

Procedure:

• Assign the stories as requiired.

                      

• Now assign the grids.
• Assign the materials as M25 for concrete and Fe 500 Fe 415 as rebar.

• Now assign the beam size.

• Now assign the column size.

• Now assign the slab.

• Mass source for siesmic load calculation.

• Assign the default load combinations.

• Add new load as brickwall,Eqx EQy with both positive and negative eccentricity as per IS1893:2016.

• Modelling of G+3 building.

• Apply the loadings into the model.

• Apply live load

• Wall load for AAC block is 3.5 KN/m .

• Beam reinforcement 

• Column reinforcement

• Export the Etabs file with base support reaction and load conditions are exported in F2k format for footing design using SAFE software.

Modelling and Designing of Pilr group foundation using SAFE software:

• Import the f2k file in SAFE software.

• Assign the materials
• Assign concrete M25

• Create another material as Fe 500.

• Slab section 500mm thick for Pile cap.

• Tie beam(600x500mm depth) assignment

• Assign the spring property for piles.

• Assign load combinations for SLS and ULS.

• Modelling of Pile cap and pile points and stiff columns.

• Assign the design grids in X and Y directions.

• Check the punching shear ratio.
• Punching shear ratio is found under limit as per IS 456.

• Pile cap bottom rebar view

• Pile cap top rebar view

Conclusion: G+3 building is modelled aad designed using ETABS.Pile group was modelled using the SAFE software.
