Display Results#
This example demonstrates how to display results in sectionproperties
.
A 165.1 x 5.4 CHS will be analysed and the differences in the display_results() output highlighted.
Create Geometry and Section#
[1]:
from sectionproperties.analysis import Section
from sectionproperties.pre.library import circular_hollow_section
geom = circular_hollow_section(d=165.1, t=5.4, n=64)
geom.create_mesh(mesh_sizes=10)
sec = Section(geometry=geom)
sec.plot_mesh(materials=False)
[1]:
<Axes: title={'center': 'Finite Element Mesh'}>
The display_results()
method will print all the results that have been calculated for the Section
object. If an analysis has not been conducted, no results will display.

The formatting can be changed by passing a formatting string to the fmt
argument, see here for more information on string formatting.

Because we have not specified any material properties, the displayed properties are purely geometric. If we assign a steel material to the CHS, we will see some results change to material property weighted values (see here for more information on how material properties affect results).
