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

AIM:

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 institute

PROCEDUTE:

• Open the etabs software go to file and click on new model.
• Model initialisation window will be appeared.
• select the indian codes and click ok.
• Click on the custom grid data and click ok.
• Now the values as per the given plans are inserted and our model will be ready.
• In the next step material has to be defined. Go to define and click on material properties and add the concrete and rebar material specification.
• 450 mm x 600 mm beam size is provided for the all the beams.
• Moment of inertia for beams and columns should be reduced by 0.35% and 0.4% respectively.
• In the next step define the slab properties by going in to define and slab sections.
• Add slab section property
• Define the stair case slab and provide its thickness as 175 mm( varies from 175-225mm)
• Draw all the beams using beam command.
• Draw all the columns using column command
• In the next step slabs are drawn using slabs command.
• As per Indian standards the length of the wall should be 5-2% in each direction.
• 150mm slab thickness will be added
• Live load at the roof floor needs to be reduced hence 2 kN/m is applied.
• Floor finish on all the floors 2 kN/m is applied.
• Time period is calculated as per clause number 7.6.2 of IS 1893
• T=0.09h/sqrtd

Tx=(0.09*16.85)/(67.7)^0.5=0.184 Seconds. Or Ty=0.09*16.85/(13.3)^0.5=0.415 seconds
