Week 2 Challenge

1.A. Column are the vertical member in the Structure that can be of varing size in dimesions

The circular section of column are provided at the upper floor of the building for the better load carrying and access purpose.

Procedure :

• Create the model in the staadd pro that can be a column.
• Go to properties in that Define paramters .
• Assign the circular shape of the column .
• The radious of the circular is given .

B. To Assignt unit system in the staad pro.

Go to file menu and then settings.

open the structural settings.

Change the dimesions as the required units .

C. To create the parameter of the design by Bay frame

By clicking on the Structural wizard option.

Click on the frame model option.

click on the Bay frame option.

Enter the parameters like the length , breadth , height and the bay frame along the length , breadth and height.

D. In Staad pro the Codal standard are incorported for the Steel , Concrerte , Aluminium.

For the Steel the codal provision are IS 800 , IS 800 : 2007 , IS 800:2007 WSD , IS 801.

For the concrete the Codal provision are the IS 456 and IS 13920 for the Seismic Design.

E.

• Go to the Design option
• Click on the define parameter
• In the design Parameter the Fck Compressive strength of RCC section is Given as 25000 KNm

2.A.

Steps Involved in RCC design are

1. Geometry : The Node loaction and the node spacing are given
2. Properties : Specify the Sectional properties of the section
3. materials : Specify the properties of the material.
4. Specifications : The pecifictions are given
5. Support : The end support are to be given
6. Loading : Need to provide the loading pattern and the loading combination
7. Analysis : Need to Analysis the modal and all the Input Specification are Given
8. Design : Finally the Design are to be done.

B.

• In STAAD, support displacement loads cannot be applied to such models when the FIXED type of support is specified.
• For the ENFORCED BUT type, there is no provision to specify a spring constant.
• The only choices, which are built into the program, are - zero stiffness.

3.A

The steps involved in analysis of a model are

• Before Analysis the model the load pattern and the load combination are to be provided to the model
• Then go to Analysis option
• Define Command
• Select the data for the analysis of the model by perform analysis , P delta analyis ,Nonlinear analysis
• It deponds upon the support conditions.

B.

The two ways to model the a structural framework is

1. Creating model by Node by Node
2. Creating model by Bay frame by

3.C

3.D.

• The Design of Staircase slab is done by Node placement
• The creation of plate is used in stair case
• BY using Generate mesh
• The stress distribution for the staircase slab is done by viewing colour in the slab of the design.

3.E.

• After complation of the Design the staad pro will automatically provide the BMD & SFD.
• By Entering to the Post procesing process click on ok.
• By clickin the beam results Deflection command.
• Reaction click the beam deflection.
