Overview - Example 1
|Top Previous Next|
The first example is a two-story, two-bay concrete frame which is shown in the figure below.
The properties of the Model are the following:
The material of the Model is Concrete with the following properties:
•Elastic Modulus E = 29 GPa
•Density d = 2500 kg/m3
There are different sections for the Columns and Beams:
Columns: Square section, 50 cm * 50 cm
Beams: Rectangular section, 50 cm * 25 cm (bending in the major axis - 50 cm is the height of the beam (along the Global Y axis) and 25 cm is its width (perpendicular to the screen))
Member geometry (Nodes and Elements)
As shown in the Figure above, where the Grid is 1 m. So the height of each floor is 3 m and each bay has a span of 5 m. The total height of the structure is 6 m, while the total width is 10 m.
Elements' orientation is also shown in the figure (It is not very important to define the elements' orientation as shown above).
There is a FX=30 kN Load acting on Node 2 and also a FX=50 kN Load acting on Node 7, as shown in the figure above.
All the beams have a uniform elemental load of 10 kN/m at the direction -Y (Global axes), as shown in the figure.
Body (Acceleration) Loads
The self-weight of all the structural elements (columns and beams) has to be taken into consideration in the analysis.
The earth gravitational acceleration is given equal to g=9.81 m/s2 (a typical value).
