2.4 PROCEDURE :

Go to the support command in the tool palet command

• Click on create support command
• There we can get option like fixed support , pin support , Fixed but
• Enforced but support
• Cable support
• Inclined support

      

2.5 First of all lets understand what is DBR? So the DBR is the Design Brief Report.So basically DBR is a short brief of what you are going to make,why you are going to make,where you are going to make. In short it is a core detail of our project. So the five topics that will include creating DBR is listed below:

• Name of the project and the location of the project.
• Structural Layout.
• Introduction to the construction methodology.
• Quality Assurance and Quality Control.
• Budget of the Project.

3.1 The structure systems in STAAD Pro software are:

• Space 
• Plane 
• Trusses
• frame

All of these we can define the in geometry, loading, deformation and joints

1. Space : has a 3D, so that it can be X,Y & Z plane in geometry, loading and deformation. Any kind of the joints and restrain can be given to the modal i.e., assign as a space.
2. Plane : the geometry is majorly in 2D accordingly the loading and deformation are also in the 2D plane i.e., mostly X&Y plane and any type of joints can be assigned here in the plane structural system
3. Frame: also 2 dimensional in nature the only changes that the loading is perpendicular to X&Z and accordingly the deformation is also perpendicular again here any kind of joints can be assigned to the frame structural system
4. Truss : geometry can be in any direction. the truss can take only axial load and it cannot have any bending or shear so the geometry, loading and deformation can all be in all 3 planes but when it comes to a joint or restraint it can only take a Pinned restrain where in the translational movement is the restricted one but the moment is release.

3.2 The co-ordunates system that are adopted in STAAD Pro software are X,Y and Z co-ordinates.

• Global axis and local axis coordinate system adopted in staad pro which is a three-dimensional analysis system
• In global axis X,Y&Z coordinate are fixed and not variable
• In local axis X,Y&Z coordinate is variable and depends on member orientation

So basically the co-ordinate system adopted in STAAD Pro software are:

• Global Axis : Mainly global axis are fixed in the co-ordinate system.
• Local Axis : Local axis is variable in nature. We can change the local axis but not the global axis.

As the STAAD Pro software. Basically it uses a conventional cartesian co-ordinate system,and in this system Y is a global axis which is in upward direction. We can say that the height of the building is always parallel to the global Y-axis just as shown in the below given image:

     

3.3 DBR : Design Basis Report (DBR) is basically a document that has certain data regarding the structure of the project. It helps you to understand where the project is located, who the client is and what is the general specification of the project. It also gives you the data i.e., considered while designing a building. This data comprises the specifications of the building. It gives you the materials considered for the building and the material properties.

Uses of DBR : 

• If we consider steel building so, it gives you what kind of prestress or post stress tendons are going to be installed in the element.
• It’s also to specify the loading conditions that have been considered for the building and it gives you the sample calculations for the loading.
• It has a general arrangement drawing. It can also have the general arrangement to column arrangement drawing of the building so that it will be easier for you to coordinate all this data with respect to the project.
• It must also give you the assumption and specifications.
• The other main advantage of DBR is when it comes to project planning it helps to avoid scope creep.

3.4 The different types of analysis options in STAAD Pro software are listed below:

• Linear Elastic analysis.
• P-Delta analysis.
• Buckling analysis.
• Pushover analysis.
• Perform analysis.

3.5 Difference between Fixed and Fixed But condition.

1) Even though the two types follow different approaches, the end result - joint displacements, member forces and support reactions - should be the same.

2) Since the number of unknowns is less in the former method compared to the latter, the time required to compute the results will also be comparatively less using the first method. If the model is large, there may be a significant reduction in time required to perform the analysis.

3) For supports directly attached to plates or solids, if the supports are subjected to artificial displacements (called sinking support or support settlements), the effects caused by such displacements can be computed only if the ENFORCED type of support is used. In STAAD, support displacement loads cannot be applied to such models when the FIXED type of support is specified.

4) 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 or very high stiffness. So, if a user plans to assign his/her own spring constant, the FIXED BUT type is the only choice.

5) If the engineer plans to analyze a model in which support conditions change depending on the loading condition (hence he/she specifies the support command multiple times in the model), there are a few restrictions on how the supports must be assigned. These are mentioned in Section 5.38 of the Technical Reference manual where the CHANGE command is described. The ENFORCED support may offer a way to overcome some of those restrictions.
