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 49-node, 52-member frame structure supported by fixed supports. The building is made of 305x127 UB 42 steel arch and is supported by 356x368 UC 202 steel columns.

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