Week 2 Challenge
1.
1.
Go to properties in that select define property select circle and give the radius for the member and assign the defined circle to the member created
2.
- While creating a model go to unit system and assign the units
- Go to geometry in that’s elect input units and assign the units
- Go to view menu in that select display options in that select structure units
3.
- Go to geometry tab in that select structural wizard in that select frame model in that select bay frame
- Give the parameters like length, height, width, No. of bays along length, No. of bays along height and No. of bays along width
4.
Euro code, ACI, IS code
5.
In design select materials as concrete and select the code and then go to define parameters and select FC then specify the value

1.
Steps involved in RCC design are
Geometry
Properties
Materials
Specification
Support
Loading and Load combinations
Analysis
Design
2.
When the fixed type of support is specified, for those degrees of freedom which are to be treated as fully restrained, STAAD assumes the displacements to be known quantities whose value is zero. Hence, these degrees of freedom are not considered for the stiffness matrix and their value is not calculated
When the enforced type of support is specified, for those degrees of freedom which are to be treated as restrained, STAAD assign a spring with a spring stiffness – translational stiff springs for translational restraints and rotational stiff springs for rotational restraints. Those 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. The one which have a stiff spring with end up having a negligible displacement and those with zero stiffness springs will have a displacement based on the structure geometry, properties and loading
3.
1.

4.
Create the staircase by using the nodes in the geometry panel
After creating the nodes assign the plate elements as the slab property after that define load cases and calculate the area load acting on the staircase and apply load cases and load combination to the staircase slab and then create a mesh on the plate element
After that run the analysis and go to post processing mode and click on plate result option in that select stress distribution result and choose the stress type accordingly and that stress distribution result is displayed
Maximum and minimum stress values are displaced
5.
After completing the design and running the analysis software will provide the BMD and SFD
After the analysis click on Post processing mode and click OK
Go to deflection command and click on beam result
In reaction command click the beam deflection
PRACTICAL
Simply Supported Beam
a. A Simply supported beam with two point loads symmetrically placed
b. Span L = 20m
c. Load P = 50kN each
d. Both P located at 5m from each support
Open the new STADD.Pro file
Create the nodes in geometry tab as per the question
Go to geomerty tab select add beam and draw the beam by using beam cursor
Go to properties tab and select define and give the rectagular dimensions for the beam
Select the created beam and assign the rectangular property to the beam
Go to material tab give the materialas concrete
As per the question load P is located at 5m from each support
Go to geometry tab and add nodes at 5m and 15m
Go to support tab and create a FIXED support and click on add and add the support to the beam using node cursor
Go to loading tab add the load cases
Asign the loads to the beam using use cursor to assign
Go to analysis tab and select analysis command and do perform analysis
Run the analysis
Fixed Beam
a. Span L = 16m
b. Uniformly Distributed Load w=9kN/m
Open the new STADD.Pro file
Create the nodes in geometry tab as per the question
Select the created beam and assign the rectangular property to the beam
Go to material tab give the materialas concrete
Go to support tab and create a fixed support and click on add and add the support to the beam using node cursor
Go to loading tab add the load cases
Run analysis
