Project 1

Model & Design a Proposed Coil Centre, Chennai using STAAD. Pro for following input from Client

Design only a Main Frame with Lean (Grid 2) & Gable Frame without Lean (Grid 15)

Assume purlin load as 8.77 kg/m

Assume Gantry girder wt. = 158.24 kg/m

Assume Rail weight = 53 kg/m

Proposed Coil Centre, Chennai

SOLUTION:

GIVEN:

Building width: 30m

Building length: 140m

Building Height : 11.7m

Roof slope: :1:10

Bay spacing : 10m

• As per the given data make the Geometry in STAAD as shown.

• Once the geometry is done assing member proper ta all the member.

• Proper specification to the member should be given in order to get the accure result.

• Once assigning the specification is done we have add the loads as per the given data.
• Defining Earthquake load as per the data.

• After defination we have add the basic load cases & & combinations.
• The basic load cases are added as shown in fig.

1. Self weight of member & dead load as per the given data.

2.Live load on rafter beam as per the given data.

3.Win load calculation

• The load application is as per the calculation shown.

• Afte successfully application of wind load we have to apply yhe crane load as shown in the fig

• Once all the load cases are done add the load combination for the following load cases.
• Here we have generated automatic load combination from staad only.

• After adding all the load combination define all the design parameters and assign it for the same.
• once all the design parameters is assigned, give the command Perform analysis & run the analysis.
• one the analysis is successfully done check the deflection limit & verify that all the members are passing .
• Here the structure is analysed without any error.

• Altough the deflection seems to be high but it is in limit as per IS 800 2007 Tble no 6
• Below fig shows no member is failing for the analysis.
