Описание

Команда Поперечное сечение балки используется для определения поперечных сечений элементов балки. В настоящее время доступны следующие типы поперечных сечений: прямоугольное, круглое и трубное.

Применение

1. There are several ways to invoke the command:
   • Press the Beam cross section button.
   • Select the Model → Element Geometry → Beam cross section option from the menu.
2. Choose the type of cross section and specify the necessary dimensions:
   • Rectangular: width and height,
   • Circular: diameter,
   • Pipe: outer diameter and thickness.
3. Optionally, press the Add button in the task panel and then click on the edge you want to have a prescribed cross section. If the edge selection is free, all remaining edges (whose cross section is not defined by other FEM ElementGeometry1D objects) will be automatically assigned.

Свойства

• ДанныеSection Type: specifies the type of the beam section (Rectangular, Circular or Pipe)
• ДанныеCirc Diameter: diameter of circular section, used if ДанныеSection Type is Circular
• ДанныеPipe Diameter: outer diameter of pipe section, used if ДанныеSection Type is Pipe
• ДанныеPipe Thickness: thickness of pipe section, used if ДанныеSection Type is Pipe
• ДанныеRect Height: height of rectangular section, used if ДанныеSection Type is Rectangular
• ДанныеRect Width: width of rectangular section, used if ДанныеSection Type is Rectangular

Ограничения

• Other types of cross sections available in CalculiX (elliptical, box and general) are not currently supported. One can edit the input file to use them.

Примечания

• For viewing results from CalculiX solver on the mesh expanded to the prescribed cross section, property Beam Shell Result Output 3D in the FEM SolverCalculixCxxtools needs to be set to True.
• Some sections require specific element types:
  • circular section - 2nd order elements
  • pipe section - 2nd order elements with reduced integration (introduced in version 0.22: reduced integration is enabled by default for beam elements and can be switched using the Beam Reduced Integration property of the CalculiX solver)
• This feature uses the *BEAM SECTION card in CalculiX.
