3. Section Properties¶
Sections relate the three-dimensional geometric properties to a lower dimensional approximation of a beam.
3.1. Beam¶
For each beam a name, type and the corresponding dimensions are required.
3.1.1. Rectangle¶
A rectangular profile can be specified by defining rectangle
as the profile type. The dimensions width
and height
are required. For example
"profiles" : [{
"name" : "steel_bar",
"type" : "rectangle",
"width" : 200,
"height" : 200
}]
3.1.2. Circle¶
A circular profile can be specified using circle
. The diameter
is required in this case. For example
"profiles" : [{
"name" : "steel_bar",
"type" : "circle",
"diameter" : 200
}]
3.1.3. Hollow Circle¶
Likewise, a hollow circular profile, (e.g. a pipe) can be specified using hollow_circle
. An inner_diameter
and outer_diameter
are required, and the inner_diameter
must be a smaller value than the outer_diameter
.
"profiles" : [{
"name" : "steel_bar",
"type" : "hollow_circle",
"inner_diameter" : 100,
"outer_diameter" : 200
}]
