DESIGN

1.1 AIM :

To assign the circular section in the column

PROCEDURE :

Create the model in the staad pro that can be a column

In properties , define parameters

Assign circular shape of the column

RESULT :

1.2 AIM :

To assign the unit system in the STAAD pro

PROCEDURE :

Go to the file menu and then the settings
Open the structural settings
Change the dimensions to the required units

1.3 AIM :

To create the parameter of the design by Bay frame

PROCEDURE :

By clicking on structural wizard option
Click frame model and the bay frame
Enter the parameters like length, breadth, height and the bay frame along the length, breadth and height

1.4 For the codal provision incorporated in STAAD pro are ;

IS 456-2000
IS 13920-2016
IS 875-1987
IS 800-2007
IS 1893-2016

1.5

Go to the Design option
Click on the define parameter
In the design Parameter the Fck Compressive strength of RCC section is Given as 25000KNm

2.1 PROCEDURE:-

1. GEOMETRY:-

The node location and the node spacing are given

2. PROPERTIES:-

Specify the sectional properties of the section

3. MATERIALS:-

Specify the properties of the materials

4. SPECIFICATION:-

The specification are given

5. SUPPORT :-

The end support are to be given as per necessity

6. LOADING:-

Need to provide the loading pattern and the loading combination

7. ANALYSIS:-

Need to analyse the model and all the input specifications are given

8. DESIGN:-

Finally the design are to be done

2.2 Fixed Support degrees of freedom which are to be treated as fully restrained, Hence, those degrees of freedom are not considered for the stiffness matrix, and their value is not calculated.

Enforced degrees of freedom which are free to displace are assigned springs of zero stiffness. Hence, for all the 6 degrees of freedom at such supports, the displacements are calculated.

3.1 Steps involved in the of a model using STAAD Pro sequentially are as follow;

Create model using node system or create by using the structural wizard
Add beams
Choose properties
Add supports
Add specificaton if any
Add loadings
Apply perform analysis
Run the MODEL
Go to post processing
View S.F , B.M and displacement

3.2 By Analytical Model
By Physical Model

STAAD.Pro Physical Modeler takes advantage of physical modeling to simplify of modeling a structure, which in turn more accurately reflects the process of building a model. Beams and surfaces are placed in the model on the scale of which they would appear in the physical world

3.3

1.FIXED:-

All the transitional and rotational displacement are restrained

2. PINNED:-

Transitional displacement are restrained but rotational oments are not restrained

3. FIXED BUT:-

The fixed support is similar to pinned support it allows us to provide the degree of freedom to view the displacement either translation or rotational

4. ENFORCED:-

When enforced supports are assigned to the structure the software allows the springs to itself and the displacement can be calculated however there is no provision to provide the spring constant

5. ENFORCED BUT:-

The software assigns the spring itself with zero stiffness or high stiffness
