Week 1 Challenge

1.

1. Write the steps involved to upload a .std file through web mail?

• Open Stadd Pro Window.
• In the Left corner We have an Option called Share below the Archive.
• Click on it.
• There we fined the share in mail option with .std file format.
• We can directly share the file in mail.

2. Name the different materials that can be designed using STAAD Pro.

• STADD Pro is Software where we can create Multi Materials for our Project.
• STADD Pro default have Some Materials in it. Namely Concrete, Steel, Aluminium Etc.
• We can also create different materials by using create new and providing the Material Properties.

3. Is it possible to capture images in STAAD Pro? If yes how?

• Yes, we can Capture the Image in STADD Pro Itself.
• Open STADD Pro and go to Utilities.
• In the tab we have, Take Picture Option.
• Click on it and we can take the picture of the model.
• This picture is saved in the selected path.

4. Name the three ways by which you can create a model.

• While Opening the STADD Pro New file we have three models.
• Analytical Model, Physical Model, and Building Model.
• Analytical Model is used for Analytical Purpose.
• Physical Model is used to display how the building will react for different physical conditions.
• Building Model is used if we have typical loading pattern, Typical Loads, Typical Floors.

5. Write the steps followed to assign properties in a model.

• To create Property. First draw a beam by using grids.
• Then go to properties tab.
• Click on create and rectangular section.
• Then Give dimensions for the section.
• And select the Material property.
• Then select Use courser to assign option and click on the beam to assign the material Property.

2.

1. Name any six design parameter involved in RCC design.

• Clear – it is used to provide Clear cover to the member.
• Fc – Compressive Strength of Concrete
• Fy – Yield Strength of Reinforcement
• MaxMain – Maximum Main Reinforcement
• MaxSec- Maximum secondary Reinforcement
• MinMain – Minimum Main Reinforcement
• MinSec – Minimum Secondary Reinforcement
  

2. What are the different cursor types available in STAAD Pro?

• Node Course
• Beam Courser
• Plate Courser
• Solid Courser
• Geometry Courser
• Physical Member Course
• Plates & Solids Courser

3. How will you generate different views for a model? State the steps involved.

• In STADD Pro View tab we have Different views.
• Front View, Back View, Right View, Left View, Top View, Bottom View, Isometric View.
• We also have Zoom In and Out, Dynamic Zoom.
• We also have view manager where we can Save view, Rename view, Add view, Export View.
• We have different display options also.

4. Explain the procedure to define a “Simply Supported” condition in STAAD Pro

• Once the material is assigned.
• Then go to supports.
• Then create support. Use Pinned support and click add.
• Then select the support and choose option of use courser to Assign.
• Then click on the Beam left and right corner.
• Thus the support is assigned to the beam.

5. Name any five topics that you will include while creating DBR.

• Introduction
• Structural Layout
• Loads and Load Combinations
• Analysis and Design Methodology
• Appendix

6. Describe the term “Multi material design” of STAAD Pro.

• STADD Pro offers multi material design, Since it have Default materials like Concrete, Steel, Timber, Aluminium in it.
• We can also define the different kinds of materials which we are going to use in our project.
• By giving the Material Properties and Design Properties we can create a new material and assign it to the member.
• Hence We say Multi Material Design.

3.

1. Name the structure systems in STAAD Pro? Explain each system?

• There are Four Structural Systems in STADD Pro
• Space
• Plane
• Truss
• Frame
• Space is a 3D framed Structure with Loads applied in any Plane.
• In plane the Geometry is in 2 D and Loading is given in 2D only
• In Frame the Geometry is in 2D and the Loading is given Perpendicular to XZ plane.
• Truss is 3D structure where there is only Axial member force and there is no bending.

2. Explain the coordinate system adopted in STAAD Pro software.

• In STADD We have Global Co-ordinate System of X in Horizontal, Z in Lateral and Y in Vertical.
• The Local Coordinate System always varies as per the material.
• The X axis is always Longitudinal to the material. Whereas the Y and Z axis are Varies.
• While applying load it is important to check the Orientation of beam to assign the load in Local axis.
• It is better to Assign Loads in Global axis.
• If we assign load to the local axis and it is changed then the load also changed.

3. Elaborate DBR and its uses.

• DBR is Design Basis Report.
• It is a report to be generated on the project to get a detailed procedure of the project.
• Structural Layout of the project. Placement of Columns and Beams and their Geometry.
• It also have the Assumptions made and the detailed explanation for the assumption.
• What are the loads and load combinations used in the project.
• The Design Parameters considered. Analysis and Design Methodology which is considered in the particular project.
• Results of Analysis and Design.
• These data’s to be documented.
• DBR is used for future reference. It gives the information like where the project is located, who is the client etc.,
• Or anyone who is joining at the mid of the project, he can go through the DBR and get a clear idea of the project.
• If there is and doubt in the project, we can refer the DBR.
• It also gives Materials considered in the project, and Details of vendor.

4. Explain the different types of analysis options in STAAD pro.

• Perform Analysis It is the first model analysis. It is used for Primary analysis.
• It is first model LINEAR Analysis.
• P Delta Analysis it is the second order Iterative analysis. It Calculates the moment with respect it the load and the deformation.
• Perform Cable Analysis, in this, every member is assigned as a cable and analysed.
• Perform Imperfection Analysis, it is used whenever the member is imperfect.
• Non Linear Analysis, It is iterative analysis. It is applied for geometry and it will not consider the plastic hinges while carrying the analysis.
• Generate Floor Spectrum, It is used for High rise building where we assign diaphragm for each floor and study the stress variation.
• Perform Direct Analysis, It is performed on basis of AISI code it is an Iterative Analysis
• Perform Pushover Analysis, it is used to analysis the earthquake load and to study the deformation of structure.
• Perform Buckling analysis, it is used for considering the buckling of the member.

5. Explain the difference between Fixed and Fixed But condition.

• Every support has, 3 translational movements and 3 rotational Movement.
• In Fixed Support Both the Translational and Rotational Movements are restrained in all the three directions.
• Hence there is no movement allowed in the fixed support.
• In Fixed But we can define Roller Support by Restricting the Parallel Forces and Movements.
• In fixed But we can also provide Spring Constant to the support.

Procedure

• Open STADD Pro. Click on New model.
• Then use Grids, Beam Grids and give start point as 0,0 and End as 16m,0
• Then properties create new.
• Rectangular beam of 450 x 450 then give material as Concrete.
• Got to Support and then create fixed and Rotational Support.
• Then Assign both supports to both ends respectively.
• Then give load. Create load case give live and add.
• Then edit load case give concentrated load of 50KN.
• Then use courser to assign and click on mid of beam.
• Then go to analysis and perform analysis and then run.
• Then take the output and shear force and bending moment diagram.
