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, specifically:
- Non-linear Analysis using small displacement theory
The Structural 3D results were compared against a third party analysis software.
The structure is a 168-node, 446-member frame structure supported by fixed supports. 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’.
