Q-2.1.5. Name any five topics that you will include while creating DBR.

Ans- 2.1.5 First of all let's 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 it, and where you are going to make it. In short, it is a core detail of our project. So the five topics that will include creating DBR are 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.

Q-2.1.6.Describe the term “Multi-material design” of STAAD Pro.

Ans-2.1.6

• It is used for 3D model generation, analysis, and multi-material design.
• The STAAD.Pro supports several steel, concrete, and timber material in a separate member
• This separate member will coordinate and then formed into a structure

Q-3.1 Name the structure systems in STAAD Pro? Explain each system.

Ans-3.1 The structure systems in STAAD Pro software are:

• Space Frame
• Plane Frame
• Truss

1. Space Frame: So basically the space frames are three-dimensional truss-like structures that are designed to carry loads for longer spans without any intermediate supports. The space frame structures are rigid and lightweight in nature and it is structurally effective. It has low transportation costs.

2. Plane frame: Plane frames are RCC or steel frame structures. It is a two-dimensional structure which is constructed with straight elements which are connected by rigid or hinged connections.

3. Truss: Trusses are created by arranging the structural elements in triangle forms which can take loads in both compression and tension.

Q-3.2. Explain the coordinate system adopted in STAAD Pro software.

Ans 3.2 The coordinate system that is adopted in STAAD Pro software are X, Y, and Z coordinates.

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

Global Axis: Global coordinate system is an arbitrary coordinate system in space, which is used to specify the overall geometry and loading pattern of the structure.

Local Axis:- Local axis is associated with each member ( element) and is used in member end force or local load specification.

As the STAAD Pro software. Basically, it uses a conventional cartesian coordinate system, and in this system Y is a global axis that is in an 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:

Q-3.3 Elaborate on DBR and its uses.

Ans 3.3 So basically the DBR ( Design Based Report ) is a project management document that consists of various information 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 consists of all the major and important structural details that are relevant or we can say that is related to the project like a 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.

Q-3.4 Explain the different types of analysis options in STAAD pro.

Ans -3.4 Full range of analysis including static, p-delta, pushover, response spectrum time history, cable (linear and nonlinear), buckling and steel, concrete, and timber design.

Q-3.5 Explain the difference between Fixed and Fixed But conditions.

Ans-3.5

Fixed condition in the STAAD Pro software is the condition where all the degrees of freedom that is horizontal or vertical or moment are fixed or we can say these conditions are restrained we cannot change accordingly. That conditions we can say are fixed conditions.

Fixed-But condition as for the fixed-end 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 degrees of freedom.

#Practical on Staad Pro Software#
To Create a STAAD Model with the following Specifications
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

Procedure-

Basic activities, are to be required for the beam model.

• Model generation: define the geometry of the whole structure using members or the first node at X-0, Y-0, and Z-0.Then, select the created node by switching to the node cursor.
• Specify the span length that is 16 meters in the X-direction and hit enter.
• 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.

Nodes

Add Beam: assign the add beam member

Section Properties: give properties to the beam with and thickness.

The size of the member assumes 400x400mm

Material Properties: assign properties to the beam such as concrete.

Supports: assign support conditions (pinned) and boundary conditions.

1. Go to support>add>pinned>select one node>use cursor assign to selected nodes>enter.

Load

Assign loads such as deal load, live load.

1. Go to loads>create>member load>global Y>-50KN.
2. Now, select the load and beam and check the radio button for assign to selected>apply>ok

Add Dead load

Add Live load

Selfweight load in Global Y direction

Central force: Distance from the starting node of the member. zero, then the load -50kN is applied at the midpoint of the member

Run the Analysis

1. After this, select the analysis method that is perform analysis from the design and analysis panel.
2. Once you are done with setting up the analysis method, go ahead and run the analysis from the analysis and design panel.
3. Wait some time for the analysis to get complete and look for errors and warnings.
4. If there are no errors or warning signs upon completion of the analysis, you're good to go.

Result: SFD[ Shear force Diagram] and BMD [Bending Moment Diagram]

1. Now, go to the post-processing mode>select the load cases>click apply>ok.
2. Then, linear the analysis results will be automatically visible on your staad screen.
3. Select beam results>Mz for bending moment>Fy for shear force diagram.
4. Make sure to check the annotate option to view the values along with the diagrams as inserted below:
