Week 2 Challenge
1.
1. Go to properties, choose to define property, circle, and then give the member's radius before assigning the specified circle to the member you just created.
2.
While creating a model go to the unit system and assign the units
Go to geometry in that’s elect input units and assign the units
Go to the view menu in that select display options in that select structure units
3.
Go to the Geometry tab in the structural wizard, frame model, and bay frame that you've chosen.
Give the specifications, such as length, height, width, and the number of bays along each of the dimensions of length, height, and breadth
4. Euro code, ACI, IS code
5. When designing, choose concrete as the material, then choose the code, describe the parameters, choose FC, and then specify the value.

2.
STAAD presupposes that the displacements are known quantities with a value of zero for those degrees of freedom that are to be viewed as fully restrained when the fixed type of support is defined. Therefore, the stiffness matrix does not take into account these degrees of freedom, and their value is not computed.
When the enforced kind of support is defined, STAAD assigns a spring with a spring stiffness — translationally stiff springs for translational restraints and rotationally stiff springs for rotational restraints — for those degrees of freedom that are to be considered as constrained. The degrees of freedom that have no restrictions on displacement are given springs with no stiffness. Thus, displacements are computed for all 6 degrees of freedom at such supports. For those with stiff springs, the displacement will be minimal, and for those with zero-stiffness springs, the displacement will depend on the geometry, characteristics, and loading of the structure.

4.
Utilize the nodes in the geometry panel to create the staircase.
Assigning the plate elements to the slab property comes after building the nodes. Next, define the load cases, calculate the area load acting on the staircase, apply the load cases, and combine the load cases with the slab for the staircase. Finally, create a mesh on the plate element.
Run the analysis, then switch to the plate result option in the post-processing mode, where you may pick the stress distribution result and the stress type accordingly. The stress distribution result is then presented.
Stress levels at their maximum and minimum are shifted.
5.
The program will deliver the BMD and SFD when the design is finished and the analysis has been done.
Select Post-processing mode after the analysis, then click OK.
Select "beam outcome" from the deflection command menu.
In response, click the beam deflection button.
Practical
1. Analyze the following structural elements and validate the results
