Week 2 Challenge

1) Aim: 1. How will you assign Circular section to column?
2. How will you assign Unit system to a .std model file?
3. What are the parameters to be specified while using “Bay Frame” option?
4. Name few codal standards incorporated in STAAD Pro software.
5. How will you specify the design compressive strength for a RCC section?

Procedure:

1.

• Create the model in the STAAD Pro that can be a column
• Go to properties in that define parameters
• Assign the circular shape of the column
• The radius of the circular is given

Result: The circular section to the column is created

2.

To assign the unit system in the STAAD pro

• Go to the file menu and then the settings
• Open the structural settings
• Change the dimensions to the required units

3.

To create the parameter of the design by Bay frame

• By clicking on structural wizard option
• Click frame model and the bay frame
• Enter the parameters like length, breadth, height and the bay frame along the length, breadth and height

4.

In STAAD pro the Codal standard are incorporated for the steel, Concrete, Aluminum
For steel the codal provision are ISO800, IS800:2007, IS800:2007, WSD, IS 801
For the concrete the Codal provision are IS 456 and IS 13920 for the seismic Design

5.

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

2) Aim: 1. State the “Input” steps involved in RCC design.
2. Explain the difference between Fixed and Enforced support condition in STAADPro.

Procedure:

1.

STEPS involved in RCC design are

• GEOMETRY
  The Node location and the node spacing are given
• PROPERTIES
  Specify the sectional properties of the section
• MATERIALS
  Specify the properties of the materials
• SPECIFICATION
  The specification are given
• SUPPORT
  The end support are to be given
• LOADING
  Need to provide the loading pattern and the loading combination
• ANALYSIS
  Need to analyse the modal and all the input specification are given
• DESIGN
  FInally the design are to be done

2.

• In STAAD Pro, support displacement loads cannot be applied to such model went 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) Aim:

1. Explain the steps involved in analysis of a model using STAAD Pro sequentially.
2. Explain the two ways in which a structural framework/model can be created in STAAD Pro software.
3. Elaborate the different support conditions in STAAD Pro.
4. How will you extract the stress distribution for a staircase slab?
5. Explain the different ways to view SFD & BMD in STAAD Pro.

Practical
1. Analyze the following structural elements and validate the results
A. Simply Supported Beam
a. A Simply supported beam with two point loads symmetrically placed
b. Span L = 20m
c. Load P = 50kN each
d. Both P located at 5m from each support

B.Fixed Beam
a. Span L = 16m
b. Uniformly Distributed Load w=9kN/m.

Procedure:

1.

The steps involved in analysis of a model are

• Before Analysis the model the load pattern and 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, delta analysis, Nonlinear Analysis
• It depends upon the support conditions

2.

The two ways to model the structural framework is

• Creating model by Node by Node
• Creating model by Bay frame

3.

Elaborate the different support conditions in STAAD Pro.

4.

• After completion of 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 slab of the design

5.

• After completion of the Design the STAAD Pro will automatically provide the BMD and SFD
• By entering to the Post processing process click on OK
• By clicking the beam results Deflection command
• Reaction click the beam deflection
