Verification Model

Medium-rise Building

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 entire out of concrete with a strength of 4,000 psi.

Evaluation points: 10
Solve Type: Non-Linear Analysis
