Verification Model

Timber Barn Frame

Overview

The purpose of this test case is to validate some of the analysis of a heavily-loaded structure with both structural and light-gauge steel, specifically:

Deflection
Forces/Moments
Linear Analysis

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

Model Setup

The structure is a 378-node, 929-member frame structure supported by fixed supports. The building consists of an assortment of steel sections, particularly wide flanges, T-sections, light gauge channels, and single angles.

Evaluation points: 10
Solve Type: Linear Analysis
