Project 2_Design & Analysis of a Hostel building at Guwahati, Assam
In this project, participants will get to experience the entire design process from modelling, analysis, design, and preparation of construction drawings. The architectural drawings of a G+3 RCC building is provided. The following information on the building is to be used:
Location – Guwahati, Assam
Function – Hostel block in an academic instituteThe walls will be made of AAC blocks. Other loadings are to be calculated as per the architectural drawings.
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.
The following design IS codes will be required for reference:
IS 875 part 1
IS 875 part 2
IS 13920
IS 1893
IS 2911 part 2
IS 456
SP 34
Students will have to produce the following:
Etabs model for the two blocks on either side of the expansion gap
Foundation details illustrating the pile & pile cap reinforcement
Tie beam details connecting the pile caps
Column reinforcement
Framing plan for typical floor
Beam reinforcements for ground floor
