Week 2 Challenge

Q.1

AIM- How will you assign circular section to column?

Assign a circular section for column-

Procedure- Under the properties icon we define the shape of geometry like if we want to select circular column than we will select circular shape and set its diameter.

Q.1B

AIM- How we can assign unit system in std.pro?

Procedure-

• Open the file tab select new model, here we will see the model information under this model information we can set units of model like English and Metric unit.
• File tab choose setting option here we can also set units.

Q.1C

AIM- What are the parameter to be specified while using bay frame option?

PARAMETER UNDER THE BAY FRAME-

• Length, height, Width and No. of bays along length, No. of bays along height, No. of bays along width

Q.1D

AIM- Name of few codal standard incorporated in stadd pro software.

Standard code incorporated in std.pro-

IS456 – For reinforced concrete design

IS800 – For steel structure design

Q.1E

AIM- Design compressive strength specify for RCC section.

Procedure-

• In menu bar we will select the Design tab under this design tab we click on define parameters.
• Now we see that a dialogue box opened here we can choose any parameter to design RCC section. Here we can also choose compressive strength (fck) of RCC section.

Q.2

AIM-What is the input step involved in RCC design?

RCC Design input step-

1. Geometry- In first step geometry of member design with the use of nodes like beam section, column section etc.
2. Properties- Properties of any geometry have to decide after geometry option IN this nproperty option we give the width and depth of geometry and assign the shape of property.
3. Material- Next we assign the material of section like wood, concrete etc.
4. Specification- We can set specification of section and can edit specification of any structure component.
5. Supports- Here we add the support to geometry like fixed support, hinge support, roller support etc.
6. Loading- After setting of support of any member we will assign the loads to the member like live load, dead load, wind load, earthquake load etc.
7. Analysis- Analysis step give us a opportunity to analysis of structure mean we can calculate here Bending moment, shear force, deflection and can show BMD and SFD of any beam section.
8. Design- Under this step we able to design any member of structure.

Q.2B

AIM- Explain the difference between fixed support and enforced support condition in std.pro.

FIXED SUPPORT-

• In fixed support no displacement occurs.
• Degree of freedom on fixed support is zero.

Enforced support-

• Enforced support also work as fixed support but Enforced but support work differently compare to fixed support.
• In Enforced but support we can set displacement of support.

Q.3

AIM- Explain the step involved in analysis of model using stadd pro sequentially.

Procedure-

• Firstly we set the shape and properties of any structure component.
• After assign loading on the structure component and analysis it.
• We choose the option analysis in stadd and perform the analysis like linear analysis, Pdelta analysis, cable analysis
• We run the analysis and find out the results like for beam we can take BMD AND SFD and we can also show the displacement of beam etc.

Q.3B

AIM- Explain the two ways in which a structural framework/model can be created in stadd pro software.

Method of Structural framework/model –

1. Nodal table method
2. Bay frame method

Q.3C

AIM- Elaborate the different support condition in stadd pro.

Support conditions-

1. Fixed support
2. Fixed but support
3. Enforced support
4. Enforced but support
5. Pinned support
6. Inclined support
7. Foundation
8. Tension/Compression Only Springs

Q.3D

AIM-How will you extract stress distribution for a stair case slab?

Procedure-

• With the use of node we create a free standing stair case.
• Next we provide properties, support, loading condition on stair.
• Now we create the analysis for staircase under the plate result option.
• Under the plate result we can show different type of stress condition like Max. absolute stress, Max. top principal major stress in the form of colour variation.

Q.3E

AIM- Explain the different ways to view SFD and BMD in stadd pro.

• Under the Analysis tab when we done the analysis we take the results like reaction, Moment and SFD,BMD directly.
• We can also take the results under postprocessing option.

PRACTICAL QUESTION

AIM-

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

INTRODUCTION-

• In stadd pro we can analysis any structure and can get results related to structure.
• For the given beam detail we calculate all the reaction and moment which is generated in beam by stadd software.

Procedure-

• Go to the file option and select new model with appropriate name, geographic location and appropriate unit.
• Set the origin of node and set the 20m node in x-direction and create a beam between the node.
• Select properties tab and define the properties for beam like size and shape of beam.
• Set the material concrete for beam.
• Fix the support to beam if we want to create simply supported beam than add hinge support to beam.
• Apply point load of 50 KN in downward direction 5m from both the support.
• Analysis the beam for loading condition under analysis tab and extract the result like reaction value, moment value and shear force diagram and bending moment diagram and displacement etc.

RESULT-

For simply supported beam stadd pro gives all the results which is used to design a beam like SFD, BMD and deflection etc.

FIXED BEAM ANLYSIS-

AIM- Analysis a fixed beam of

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

INTRODUCTION-

• In stadd pro we can analysis any structure and can get results related to structure.
• For the given beam detail we calculate all the reaction and moment which is generated in beam by stadd software.

Procedure-

• Go to the file option and select new model with appropriate name, geographic location and appropriate unit.
• Set the origin of node and set the 16m node in x-direction and create a beam between the node.
• Select properties tab and define the properties for beam like size and shape of beam.
• Set the material concrete for beam.
• ADD the support to beam if we want to create Fixed supported beam than add fixed support to beam.
• Apply UDL of 9 KN/M in downward direction.
• Analysis the beam for loading condition under analysis tab and extract the result like reaction value, moment value and shear force diagram and bending moment diagram and displacement etc.

RESULT-

For simply supported beam stadd pro gives all the results which is used to design a beam like SFD, BMD and deflection etc.
