Project 2_Design & Analysis of a Hostel building at Guwahati, Assam
Aim: To design and analysis of G+3 hostel building in Etabs and Foundation in SAFE.
Given:
- The walls will be made of AAC blocks.
- The buildings rests on type 3 soil. Piles of length 10 meters and 500 mm diameter with a load-carrying capacity of 280 KN is to be used.
- The ground floor level will be at a height of 2 meters above the existing site level to avoid floodwater enter the building.
- M25 grade of concrete with Fe500 for longitudinal reinforcement and Fe 415 for shear reinforcement is to be used.
Procedure:
Open Etabs and open a new model
Enter the story height and grids according to the architectural plan
After this we will get a plan
Define materials
For shear reinforcent
Define secion properties
Beam
Column
Slab
Start geometric modelling of beams,columns and slabs
The result will be this
Applications of load:
Define load pattern
Define dead load
Define live load
Define floor finishes
Define mass source
Define diaphragms
Define load combinations
Define response spectrum
Add response spectrum in load cases
Check the model
View base reactions
Modal participating mass ratio
Story drift in RSx direction
Story drift in RSy direction
After everthing's alright, run concrete design
Elevation A view of column for longitudinal Reinforcement
Shear reinforcement
Designing beam along grid 1
The reinforcement detailing for beam along grid 1
Designing the reinforcement for column in grid A
Shear value
Reinforcement detailing for column
Export this model to SAFE software to design and analys the foundation
Open SAFE software and import the saved Etabs file
After defining material property,section property
View live load above
Loads on the foundation
Draw piles and beams accordingly
Add soil subgrade property to the foundation
Add point spring to tge piles
The design value
Add slab design strips
Result:
A G+3 hostel building and its foundation has been designed and analysed using Etabs and SAFE softwares.
