Week 1 Challenge

ANSWER:

Aim:-

To write a brief and elloborate answer for the given essay questions and the practical one of the staad model.

Introduction:-

In this challenge was going to brief about the introduction of staad pro software and how to upload a file, the different materials, capture the images, three ways of create a model and how to assign the properties. the second one was name of the design parrametres, curser types available in staad pro, generate a different model, the procedure to define the simply supported condition, the topics involved while creating DBR and the multi material design. The thired one was structure system, coordinate system, DBR and its uses, different types of alalysis option and diffrents between fixed and fixed but condition. Finally create a staad model and give its specification and draw a SFD and BMD diagrams.

Procedure:-

Q1) Ans:-

1. Steps Involved to upload a .std file through web mail:

• Open the staad pro software on your desktop and click the share option on appears the left side of list bar,
• After clicking the share option then goto the send mail option.
• Then browse for the .std file, then send throug mail.

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

• Concrete
• Steel
• Aluminium
• Timber
• Composite Sections.

3. It's possible to capture a image and how:

• Yes, its a poissible to capture a image on staad pro.
• we have option on take picture in the utilities tab on top menu bar.

4. Three ways to create a model:

• Analytical model
• Physical model
• Building planner model.

5. Steps follwed to assign the properties in the model:

• Goto the properties panel on the menu bar.
• Then select the materials or define option the panel.
• Then choose the material what type you want.
• Then assign it to selcted option or view option.

Q2) Ans:-

1. Six design parameters involved in RCC design:

• Clear cover
• FC compressive strength of concrete
• FU tensile strength of steel
• Maximun main dia of bar
• Code of practice
• End concrete design.

2. Different cursor types available in STAAD Pro:

• Node cursor
• Beam cursor
• Plate cursor
• Solid cursor
• Geometry cursor
• Member cursor
• Plates or solid cursor
• Load cursor.

3. Different views of model and its steps:

Goto the view panel on the top menu bar, there is the option like below for the different views

• Isometric view
• Top view
• Bottom view
• Left view
• Front View
• Right View
• Back view

4. Procedure to define a simply supported condition:

• Goto the support panel on the menu bar.
• Then choose a create option on the right side panel.
• The various supportes are appeared like fixed, pinned, fixed but, inclined, enforced and enforced but support.
• Assign the support on both end nodes is simply support condition beam.

5. Any five topices that you will include while creating DBR:

• Name of the project and location of the project,
• Structural layout,
• Construction methodology,
• Quality assurence and quality control,
• Budget of the project.

6. Descripe "Multi material design":

The term multi material design of sttad pro defines the structure that is desined by implementing more than one structural material. Suppose I an designing an RCC building but at the same time few parts of the RCC building are composed of different materials like steel in order to make a sheds, garage, etc. so this type of design with different materials is known as the "Multi Material Design".

Q3). Ans:-

1. Name the structure system and explain each systems:

• Space frames.
• Plane frames.
• Trusses.

1. Space Frames: so basically the space frames are3D truss like structures that are designed to carry loads for longer spans without any intermediate supports. the space frame structures are rigid and light weight in nateire and it is structurally effective. It has low tranportation costs.
2. Plan Frames: Plane frames are RCC or steel frame structures. If is a two dimensional structure that is constructed with staright elements which are connected by rigid or hinged connections.
3. Trusses: Trusses are created by arranging the structural elements in structural elements in the triangular forms which can take loads in both compression and tension.

2. Explain the coordinate system adopted in staad pro:

• The coordinate system adopted in the staad pro was

1. Global coordinate sysytem and
2. Local coordinate system

Global coordinate system:

• The global coordinate systems are fixed in the coordinate systems.

Local Coordinate system:

• Its various on the nature. we can change the local coordinate sysytem but not in the global coorinates.

3. DBR and its uses:

• Basically the design basis report (DBR) is a project management document which consist of various information regarding the construction of the structure.
• This BDR can give the detailed report which gives the minute detail of the ongoing construction work.
• This report basically consist of all the major and important structural details that is relevant or we can say that is related to the project like description of the client, site information, special requirements, the technical requirements, components required, the project requirements and other issue related to the construction.

4. Different types of analysis options in staad pro:

• The different types of analysis option in staad pro are

1. Linear elastic analysis
2. P-Delta analysis
3. Buckling analysis
4. Pushover analysis.

5. Difference between fixed and fixed but condition:

Fixed Condition:

• Fixed support can resist all type of movement in all directions. that is a fixed support have reactions for all forces and also for moments.

Fixed But support:

• In the fixed but support condition is self definitive. There have facilities to make release supports in all desired directions but against forces and moments.

PRACTICE: -

Create a Staad Model:

a). A beam of span 16m:

• Open a staad pro software.
• On a new tab option enter file name and select the location of the file then create a new analytical model.

• After opening on the node window enter the node value as 0,0,0 on x,y,z respectively on node 1.
• Then enter the node value 16,0,0 on x,y,z respectively on node 2.

• Then the Beam window or add beam option enter the nide A as 1 and node B as 2 the beam was formed beam span of 16m attomatically.

b). Supports:

• Assign the properties and materials as per standard condition.

• Assigned the support at one end on fixed support and other end as fixed but support on below given.

c). A point load at 50 kN at the mid end:

• Switch to the Loading option then add the load case detail on Point load
• Then put the value of concentrated load on 50kN on mid of span at -Y direction.
• Then assign the load on use of assign to view method.

d. Draw SFD and BMD:

• Switch to analysis option,
• Add analysis command as perform analysis,
• Run the analysis, display the no error then select goto post processing model and select done option.

• Then select beam result option on the menu bar,
• Then select shear force tools Fx, Fy and Fz the shear force raction will be appear,
• then annotate the shear on end, mid and maximum.

• Again select the moment commands only will appear the moment values
• Then annotate it.

Result:-

Written the brief and ellobrate answers for the given essay questions and the staad model also created succesfully.
