Overzicht

The purpose of this test case is to validate some of the analysis of a structure with custom sections with the inclusion of shear area in the analysis, specifiek:

  • Doorbuiging
  • Krachten/Momenten
  • Non-linear Analysis using small displacement theory

De structurele 3D-resultaten werden vergeleken met analysesoftware van derden.

Model instellen

The structure is a 168-node, 446-staafframestructuur ondersteund door vaste steunen. The building exterior consists of 5 rectangular sections, with the base section having a dimension of 120×220 and where every succeeding level, the depth of the section decreases by 20mm. The horizontal members, as well as the exterior braces, have a circular section with a diameter of 30. The rectangular sections are comprised of a material property labelled as ‘coconut wood’, while the circular sections are made of a material property labelled ‘bamboo’.
