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
}]
