Week 2 Challenge
QUESTION 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
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
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.
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
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
QUESTION 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. 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
QUESTION 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
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. Elaborate the different support conditions in STAAD Pro.
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
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
