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.

• 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

GIVEN :

• The 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.

PROCEDURE :

• Open Etabs and select the new model.
• Enter the story height and grids accornding to archietectural plan as shown below

• Next we have to define materials>M25 & HYSD500(longitudinal reinforcement),HYSD415(shear reinforcement)

• Next we have to define section properties
• Beam = B400*500

• Column = C 650*650

• Slab = 150mm

• Drw the beam , column & slab using quick draw tools as shown below

• Applications of load
• Define load pattern>dead load

• Define live load

• Define floor finishes,

• Define mass source

• Define diaphragm,

• Define load combinations

• Define Response spectrum

• Add Response spectrum in load cases,

• Check the model & Run Analysis

• view base reactions

• Model participating mass ratios

• Run Concrete design

• Longitudinal reinforcement

• Shear reinforcement

• The reinforcement detailing for beam along grid 1

• shear value

• designing a reinforcement for column along the grid A

EXPORT THIS MODEL TO SAFE SOFWARE TO DESIGN AND ANLYSIS THE FUNCTION:

• Open the SAFE software and import the saved Etab file

• Define material properties and 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 the piles

• Design value

• Add slab design strips

RESULTS :

A G+3 Hostel Building and its Foundation has been designed and analysed using Etabs and SAFE Sofwares.
