Overview
The purpose of this test case is to validate some of the analysis of a medium-rise concrete structure, specifically:
- Deflection
- Forces/Moments
- Non-linear Analysis
The Structural 3D results were compared against a third-party analysis software.
Model Setup
The structure is a 270-node, 522-member frame structure supported by fixed supports. The building consists of 12″ x 24″ beam sections and 24″ x 24″ column sections. The structure is made entirely out of concrete with a strength of 4,000 psi.
Evaluation points: 10
Solve Type: Non-Linear Analysis
