Scaffolding Structural Design Tutorial

Learn how to model, analyze, and design scaffolding structures using Structural 3D and the Scaffolding Design module. We will go through modeling the scaffolding members and then analyzing them against European, US, or Australian.

Introduction

In the following tutorial, we will explore how to model scaffolding structures in SkyCiv as well as complete scaffolding design relating to European, Australian, and US codes.

This tutorial includes a step-by-step guide on:

  • Modeling and analyze scaffolding structures in SkyCiv S3D
  • Designing scaffolding structures
  • Performing Connection Force Analysis
  • Generate Reports

To start out, open Structural 3D to begin modeling your scaffolding structure. You can use imperial or metric units depending on if you are planning to analyze against US or European/Australian standards, respectively. You can modify the units for your model by going to settings > unit system and selecting metric/imperial.

Modeling Scaffolding Structures

The scaffolding structure will be modeled using member elements. Firstly, we define the nodes for the start and end points of the member. To create the nodes, go to the Nodes menu. From this menu, we can input the X, Y, and Z coordinates for each node individually, clicking Apply for each node to add them to the model.

Once your nodes have been laid out, you can then input your individual members. Each member will be defined with a starting and ending node. By inputting each member, you can define which nodes it originates at, and ends at, as well as the Section that will be used to determine the material and structural properties of your members.

Your final step in modeling will be determining the section for each member. It is critical that the material chosen for your section is steel, as this is the only material that matches up with the material you will utilize to design with the integrated Scaffolding Design calculator. As the Scaffolding Design calculator evaluates steel members, you must ensure that the material you have chosen for your section (and in turn, the sections you choose for each member) matches correctly.

Additionally, the Scaffolding Design calculator is designed to check hollow circular sections only. So it is critical that the section you choose in this step is also hollow and circular.

Once you have chosen the right section for each member and modeled your entire structure, it is time to analyze your design and complete your design checks.

Analyzing Your Design

After finishing your modeling, you can click on the “Solve” bubble in the top right corner. This will perform the structural analysis of the scaffolding structure, evaluating the material strength, inputted loads, and support conditions. Once this is done, S3D will show you the final solved model. If you run into any errors, the dialogue box will let you know how to address them to move forward with your design.

Launching Scaffolding Member Design

The last step is launching the Member Design module for scaffolding design. Once you click on the “Design” bubble in the top right corner, it will launch a dialogue box asking you which design module you would like to use to analyze your structure. Select “Other Design” to launch the list of available design modules.

From here, you can select one of the three available Scaffolding Design Calculators. At this time, scaffolding design in SkyCiv is available for AZ/NZS 1576, BS/EN 12811-1:2003, and AISC 360.

Be sure that, in your model, the scaffolding members are made up of circular, hollow, steel sections. If your sections or material has not been chosen correctly, you may get the error: “No Members Imported. Please check that your sections are circular hollow and materials are set to ‘steel’.” If you get this error, navigate back to the “Model” step, go back into Section Builder, and update your scaffolding members’ sections accordingly.

Generating Reports

Once you have launched the Scaffolding Design calculator, you can see if each member is passing or failing based on the design checks the calculator has performed. At any time, you can click the “X” in the top right-hand corner of the calculator to return to S3D and update your design further.

Additionally, you can click on the “Summary Report” button to view a report on all the members or view detailed calculations with hand calcs and code references by clicking on the “Report” button next to any of the individual members.

Within the report, you can see a more detailed breakdown of each specific design check to further inform your design choices as you work to optimize your scaffolding structure. You can print this report and use it or the summary report, when putting together a summary of your calculations. Congratulations! You’ve successfully completed the design of a Scaffolding Structure using SkyCiv’s Scaffolding Design calculator!
