Shell Frame

Overview

The purpose of this test case is to validate some of the analysis of an asymmetric structure, specifically:

  • Deflection
  • Forces/Moments
  • Linear Analysis

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

Model Setup

The structure is a 53-node, 138-member frame structure supported by fixed supports. The structure is made entirely of steel round diameter 20 sections.

Evaluation points: 10
Solve Type: Linear Analysis (14 iterations)
