## Unit 4: Extending BIM for Structural Analysis and Design

## Overview

This unit provides an overview of the analytical model in Autodesk® Revit® Structure software. It highlights the differences between the physical and analytical model, and then introduces powerful structural extensions you can add to Revit Structure. The unit includes a brief review of modeling in Revit Structure followed by an introduction to the concept of linking to third-party analysis programs. In addition, the unit introduces structural loads, load cases, and load combinations.

## Objectives

After completing this unit, students will be able to:

- Define the Revit Structure analytical model.
- Know the differences between physical and analytical models.
- Understand the basic concept of structural loads, load cases, and load combinations.
- Understand how the basic tools work in Revit Structure related to using Building Information Modeling for structural analysis.
- Understand the relationship between analysis software, such as Autodesk® Robot™ software, and BIM applications such as Revit Structure.

## Exercises

The following practice exercises are provided:

- Exercise 1: Composite Beam Design
- Exercise 2: Load Takedown
- Exercise 3: Static Analysis of Slabs
- Exercise 4: Static Analysis of Beams
- Exercise 5: Revit to Robot Link
