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

Aim: Design & Analysis of a Hostel building at Guwahati, Assam

Introduction:

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

Procedure:

The Above mentioned Project is done as per Is 1893 Part-1 2016 the following procedure is as follows,

Step-1

• Open E-tab Software and Select a new file and save the project as Final Project.
• Now the is step is to set the Model initialization.
• Select the built in option.
• In which select unit as metric SI.
• Steel section database as Indian.
• Steel Design code as IS 800 2007.
• Concrete Design code as Is 456 2000 and press ok as shown below.

Step-2

• Now Giving the Spacings of Grids.
• Select grid only option and press ok.
• Now select display grid data as spacing.
• and provide spacing as Shown in Architectural Plan Given by architect
• 14 grids along x and 4 grids along y as mensioned in question.
• As shown below.

Step-3

• Select the Storey Data and input the data as mensioned.
• That is select 5 story that is Plinth level and 3 Floors and Roof.
• With 1st floor as master storey and remaining 3 floors as its copy as shown below.
• After completely renaming the Storey press ok.

Step-4

• Now its time to define the materials Properties
• Select concrete as Indian and M30 grade.
• For steel select Rebars Indian ie HYSD 415 grade.
• After completing Selct ok as shown Below.

Step-5

• Now give Section Properties for Column, Beam and Slab ie.,
• For Column select size as 450x600mm
• For Beam 300x500mm
• And For Slab 125mm thk.

Step-6

• Now placing of Columns and Beams is done.
• select the quick column option and select Column C1 i.e., 450x600 and place it where required.
• Simillarly select quick beam and select the grids where beams are required.
• and also select quick slab selection and place the slab of given size i.e., 125mm thk.
• And Must be noted that the all storeys option should be selected.

Step-7

• Now its time to assign the Supports whether fixed or hinge or pined
• In this case hinge support is given that is restricted along x and y only.
• it is done by selecting the points from base plan and assigning the hinge support as shown below.

Step-8

• Defining of loads acting on the building that is
• Dead load, live Load, Wall Load, and Earthquake load.
• For Earthquake load There loads are given those are EQ in X, EQ in X+, EQ in X- and EQ in Y, EQ in Y+ and EQ in Y- As shown below.

Step-9

• Assigning the Live Load, Dead Load to the Structure
• Brick load =4.45N/m
• And Live Load as 4 for Corridor, 2 for Room.
• and Assign the loads as shown in Is 456 2000

Step-10

• Now Apply the Modal Case and Modal Mass.
• And Select the Load Combination and also Select the Load Cases as shown Below.

Step-11

• Now Apply Run the Analysis and Check Whether th Modal is Good.
• Next Analyse the Model.
• And Hence the modal is Analaysed as Shown Below.

Step-12

• Now the Neccesary check has been checked as per Is 456 2000 and IS 1893 2016
• Hence the Model is Checked and Redy for the Designed

Step-13

• Now after Completing the Modeling now select the Design the beam by selecting concrete design logo
• Now Select the Beams and Selct the lonitudinal reinforcement and Shear Reinforcement
• And Also do the same For Column as shown Below

Step-14

• Now Select the Column of A2 column
• And Selcect the Longitudinal Reinforcement
• And Select Shear Reinforcement and Also Check for Rebar Percentage that is it should not be more than 4

• Hence the Longitudinal Reinforcement of Column A2 Is 4575 N/mm
• And Shear Reinforcement 498.80and 665.06 at top and Bottom

For Shear Reinforcement

And Shear Reinforcement 498.80and 665.06 at top and Bottom

Step-15

• Now Select the Beam of A4-B4 Beam
• And Selcect the Longitudinal Reinforcement
• And Select Shear Reinforcement and Also Check for Rebar Percentage that is it should not be more than 2.5

• Hence the Beam Shows Required Rebars is that is 862
• And Shear as 768
• Hence the Sheet is already prepared we just need to provide the value as shown Below

Step-16

• Now the time for Foundation in order to design for Pile Foundation Necesaary details has to be Calculated.
• So check the Load acting on the Column A2
• 
• So now Go to Safe 2016 Software and Design Manually
• Open New File And Save as Footing
• Open the Safe 2016
• Select the file option and Select new model
• Select the IS code and all necessary modifications as shown below.

Step-17

• Select Grid only option and give proper details.
• Add the dimension of Pile cap and column.
• As per IS 2911 part-2 and SP 34 the edge of pile to cover should be 100mm to 150mm so we assume 200mm
• And the distance between two pile should be 2.5D hence for 500mm dia pile 1250mm is required.
• The Load given is 780 KN and pile capacity is 200KN hence no of pile =4no.s as shown below

• Hence the Pile Foundation is Designed As per Is 456 2000
• This Completes the Project 2 Of Designing G+3 Hodtel in Guwait, India
