This separate member will cordinate and formed in to a structure
3.
1. Name the structure systems in STAAD Pro? Explain each system?
Ans)
A structure can be defined as an assemblage of elements. STAAD.Pro is capable of analyzing and designing structures consisting of frame, plate/shell, and solid elements. Almost any type of structure can be analyzed by STAAD.Pro.
SPACE - A3D framed structure with loads applied in any plane. This structure type is the most general.
PLANE - This structure type is bound by a global X-Y coordinate system with loads in the same plane.
TRUSS - This structure type consists of truss members which can have only axial member forces and no bending in the members.
FLOOR - A 2D or 3D structure having no horizontal (global X or Z) movement of the structure [FX, FZ, and MY are restrained at every joint]. The floor framing (in global X-Z plane) of a building is an ideal example of a this type of structure. Columns can also be modeled with the floor in a FLOOR structure as long as the structure has no horizontal loading. If there is any horizontal load, it must be analyzed as a SPACE structure.
Specification of the correct structure type reduces the number of equations to be solved during the analysis. This results in a faster and more economic solution for the user. The degrees of freedom associated with frame elements of different types of structures is illustrated in the following figure.
2. Explain the coordinate system adopted in STAAD Pro software.
Ans) The coordinate system that are adopted in STAAD Pro software are X,Y and Z co-ordinates.
Local Coordinate system-
A local coordinate system is associated with each member. Each axis of the local orthogonal coordinate system is also based on the right hand rule.
Global cordinate system -
This coordinate system is a rectangular coordinate system (X, Y, Z) which follows the orthogonal "right hand" rule.
3. Elaborate DBR and its uses.
Ans) DBR stands for Design Brief Report, is a project management document which consist of various informations regarding the construction of the structure. This DBR is a detailed report which tells the minute details of the ongoing construction work. It defines the final stage in the process of defining the Client's requirement for the 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 if any,the technical requirements,components required,the project requirements and the other issue related to the construction.
4. Explain the different types of analysis options in STAAD pro.
Ans) The different types of analysis options in STAAD Pro software are:
Linear Elastic analysis.
P-Delta analysis.
Buckling analysis.
Pushover analysis.
5. Explain the difference between Fixed and Fixed But condition.
Ans)
Fixed condition in the STAAD Pro is the condition where all the degrees of freedom that is horizontal or vertical or moment are fixed or we can say these coditions are restrained we cannot change accordingly. Those condition we can say are the fixed conditions.
For the fixed But condition, we can say that this condition can be customized its end conditions accordingly. In this condition we can change the end condition it is not restrained.We can release some of the required degree of freedom.
PRACTICAL: 1. Create a STAAD Model with the following Specification a. A beam of span 16m b. Support : Fixed on one end and Roller support(Horizontal) on the other end c. A point load of 50 kN at the mid-point d. Draw SFD and BMD using software
Ans)
AIM: To create a staad model with the give specifications
PROCEDURE:
a)A beam of span 16m
Initially open the STAAD pro Software and click on New
Now enter the project details
Specify a location within the system and enter the units
Then, click on create to start a new project.
Now draw the Beam of required Span
To model the proposed beam, go to geometry and create the first node at X-0, Y-0, and Z-0.
Then, the second node at X- 16m, Y- 0 and Z- 0.
Both the ends of the required beams are created
Now go to add beam select first node and then second to create a beam of the proposed length.
b). Support : Fixed on one end and Roller support(Horizontal) on the other end
Go to support -->create -- >fixed -- >add --> select one node --> assign to selected nodes -->enter.
Similarly, for another node click on create --> fixed but --> add then select the other node -->assign to selected --> then ok.
Next go to properties and add wdith and thickness to the section and assign to the beam
Assign concrete material to the beam.
c). A point load of 50 kN at the mid-point
Go to loads --> Add --> member load --> Globa Y direction --> Force -50KN --> d1-5, d2-5 --> OK.
Now, select the load and assign to the beam by selecting assign to selected.
RUN THE ANALYSIS:
Go to analysis , select the analysis method that is perform analysis from the design and analysis panel.
Once you are done with setting up the analysis method, go ahead and run the analysis from the design and analysis panel.
Wait some time for the analysis to get complete and look for errors and warnings.
If there are no errors or warning signs upon completion of the analysis, the analysis is completed.
d).Draw SFD and BMD using software
Now, go to the post-processing mode then select the load cases and click apply.
Then, all the analysis results will be automatically visible on the staad screen.
Select beam results>Mz for bending moment>Fy for shear force diagram.
Make sure to check the annotate option to view the values along with the diagram
