Verification Model

Timber Barn Frame


Overview

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:

  • Deflection
  • Forces/Moments
  • Linear Analysis with Shear Area

The Structural 3D results were compared against a third-party analysis software.

Model Setup

The structure is a 46-node, 108-member frame structure supported by fixed supports. The building consists of timber sections from the NDS catalogue for Sawn Lumber. The sections are comprised of the default Oakwood properties as provided in Structural 3D.

Evaluation points: 10
Solve Type: Linear Analysis
