Week 2 Challenge

Q1

1.1 How will you assign the Circular section to the column?

AIM,

To assign a circular section to the column.

INTRODUCTION,

• Columns are the vertical member in the structure that can be of varying sizes in dimension.
• The circular section of the column is provided on the upper floor of the building for the better load carrying and access purposes.

PROCEDURE,

• 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.

 1.2 How will you assign the Unit system to a .std model file?

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.

1.3.What are the parameters to be specified while using the “Bay Frame” option?

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.

1.4 Name a few codal standards incorporated in STAAD Pro software.

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.

 1.5 How will you specify the design compressive strength for a RCC section?

• 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.

Q2

2.1 State the “Input” steps involved in RCC design.

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.

2.2 Explain the difference between Fixed and Enforced support condition in STAADPro.

• 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.

Q3

3.1 Explain the steps involved in analysis of a model using STAAD Pro sequentially.

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.

3.2 Explain the two ways in which a structural framework/model can be created in STAAD Pro software.

The two ways to model the structural framework is,

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

3.3 Elaborate the different support conditions in STAAD Pro.

3.4 How will you extract the stress distribution for a staircase slab?

• 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.

3.5 Explain the different ways to view SFD & BMD in STAAD Pro.

• 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.

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
