Verification Model

Two-storey Structure

Overview

The purpose of this test case is to validate some of the analysis of a typical structure with both concrete and steel elements, specifically:

Deflection
Forces/Moments
Linear Analysis

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

Model Setup

The structure is a 75-node, 143-member frame structure supported by pinned supports. The building consists of rectangular concrete sections and trusses comprised of L-3x3x1/4 sections.

Evaluation points: 10
Solve Type: Linear Analysis
