1. Purpose of the feature

The Leg Loads by Selected Bay feature simplifies the process of calculating dead and live loads applied to the bay legs for a modular scaffold system. By using this feature, you can easily select a bay within the model, which has been added using the Bay tool.

Additionally, any components that are added to the bay via the Item tool will automatically be included in the load calculations, ensuring accurate and comprehensive results.

Prerequisites

Microsoft Excel must be installed on the machine prior reports generation.

 
 

2. User Interface overview.

The tool is located under the Engineering tab.

To open the tool menu please double click on the tool.

FUNCTIONALITY

File Name and Naming Components in Reports

The File Name is a view-only value generated automatically based on the following structure:
Prefix – Job Number – System – Report Name – Selection Box Name – Postfix – Revision.

Prefix: A customizable text field that can be filled by the user. If provided, it will appear at the beginning of the report name and be included in the File Name.
Report Name: A user-defined text field specifying the name under which the report will be saved. If left blank, the report type name will be used as the default.
Postfix: A customizable text field that can be filled by the user. If provided, it will appear at the end of the report name and be included in the File Name.
These components provide flexibility in naming reports while maintaining a consistent structure for organization and easy identification.

Checkbox options

Include Job Number: When selected, the job number from the Project Info will be added to the file name.
Include System: When selected, the system name will be included in the file name.
Include Selection Box Name: When selected, the name of the selection box will be added to the file name.

 

 

Revision

 

 

The "Revision" field allows the user to enter a custom Revision text value to be displayed at the end of the specified report name and will also be included in the file name.

                  

 

Report Type

 

 

The "Report Type" is a drop-down list that offers the following available report options:

  • Leg Loads by Area - calculates and creates reports for leg loads by area (rectangle or polygon) picked in the model.
  • Leg Loads by Bay - calculates and creates reports for leg loads for a bay added by using the Bay tool (any extra components added over the bay will not be considered in calculations).
  • Wind Loads Report (available in AU only) -  calculates and creates reports for wind load cases available for Layher and Kwikstage scaffold systems only.
  • Scaffold Tie Register - generates tie register in Excel format. 

Show numbering – when selected, the model view will be updated to display existing engineering selection box names and wall tie numbers. Deselecting this option will remove these elements and update the view model accordingly.

                 

Loading Details tab

 

The following fields require user input and are used in the Live Load calculations on the Leg Load tab under the Live Load section:

Main Platform – Max UDL:
Enter a value of maximum Uniformly Distributed Load (UDL) distributed over the main platform to be used in the Live Load calculations for the main platform on the Live Load table.

Consoles – Max UDL:
Enter a value of maximum Uniformly Distributed Load (UDL) distributed over the main platform to be used in the Live Load calculations for the console brackets on the Live Load table.

Number of Lifts Loaded (Main Platforms):
Enter a number of lifts to be loaded at the same time to be used in the Live Load calculations for the main platforms on the Live Load table.

Number of Lifts Loaded (Consoles):
Enter a number of lifts with consoles to be used in the Live Load calculations for the console brackets on the Live Load table.

These inputs are essential for accurate Live Load calculations and should be filled out thoughtfully.

Leg Load tab

 

Engineering Selection Box Settings:

New Box Name: Enter a text value that will be assigned as the name for a newly inserted engineering selection box.
Existing Box Name: A drop-down list displaying all available engineering selection boxes currently created in the model.
Checkbox Options:

Show Ratio Per Selection Box: When selected, the ratio values will be displayed in the model once the engineering selection box is calculated (after clicking the "Get Data" button). 

A component ratio represents the component mass to be included into the dead load calculations. As an example, 0.5 ratio of the component represent half of the component mass to be included into the dead load calculations. 

These values will disappear when the view is updated or redrawn.
Control Buttons:

Zoom Selected: Zooms in on the currently selected engineering selection box in the model view.
Create Screenshot: Captures a screenshot of the current model view and stores it in the "Reports" folder within the model folder. The screenshot will be named after the selected box name.
Show Screenshot: Displays the previously created screenshot for the currently selected box name.

Standard location

The dropdown list displays the four available standard locations. 

When a location is selected, the corresponding engineering selection box will be highlighted in the model and calculation results displayed in the dead and live load tables for the leg selected.

The available locations are:

  • Inner-End1
  • Outer-End1
  • Inner-End2
  • Outer-End2

Total leg load per selected box

Displays total leg load per selected box for one of the four options as in the point 7 above:

  • Inner-End1
  • Outer-End1
  • Inner-End2
  • Outer-End2

Model Selection and Data Grid Filtering

Filters Rows to Selected Scaffold Items in Model: This button filters the data grid rows based on the currently selected objects in the model.

Selects Scaffold Items in Model from Selected Rows: This button selects scaffold items in the model based on the profiles of the selected rows in the data grid. To add elements to the current selection in the model, hold the Shift key while selecting.

Searches in Table: The search box allows to dynamically filter the table by entering characters. It will match any part of the profile name, whether it’s the entire name or just a few characters.

Resets Table: Clicking this button clears the search box and removes any filters applied to the table, including the filter set by the "Filter Rows to Selected Scaffold Items in Model" button.

Dead load data grid

This data grid summarizes the dead load for structural analysis of a leg selected in the Standard location (as above in 7) . 

Helps to preview material weights and overall structural loads for project planning or safety assessments.

Components are grouped by type (e.g., Base Collar, Base Plate 60), with details like unit mass, selected quantity, and total mass. 

Down the bottom there is a summary of Total mass of components captured by the selection box (per leg selected in the Standard location (as above in 6). Total dead load of components captured by the selection box (per leg selected in the Standard location (as above in 6).

Live load data grid

The table ensures accurate live load assessment for a selected leg (as set in the Standard location as above in 6) by considering factors like platform area, load distribution, and selection ratio. This allows designers and engineers to ensure the scaffold meets safety and stability requirements.

Example:

Imposed Load:

  • The live load imposed on the platform, typically based on the intended use (e.g., workers, equipment, materials).

Main Platform Dimensions:

  • 2.572 × 1.088 meters: The platform's length and width.
  • Total Area: Calculated as 2.572m×1.088m=2.80m22.572 \, \text{m} \times 1.088 \, \text{m} = 2.80 \, \text{m}^2

Selection Ratio:

  • A fraction (0.25 in this case) representing the percentage of the platform considered for the load calculation.

Lifts Loaded:

  • Indicates the number of levels or lifts on the scaffold subject to the live load. Here, only one lift is loaded.

Uniformly Distributed Load (UDL):

  • 2.00 kN/m²: The load applied per square meter of the platform area.

Selected Area:

  • 0.70 m²: The portion of the total area used in the live load calculation, derived from the selection ratio.

Total Load:

  • 1.40 kN: The total live load on the selected area, calculated as 0.70m2×2.00kN/m2=1.40kN0.70 \, \text{m}^2 \times 2.00 \, \text{kN/m}^2 = 1.40 \, \text{kN}

Down the bottom there is a summary of Total live load captured by the selection box (per leg selected in the Standard location (as above in 6). 

Initiates the process of a bay selection  - a bay added by the Bay tool in the model needs to be picked to define a box capturing components to be calculated.
Gets data from a bay being selected in the model and calculates load cases for the bay. If the bay is not selected in the model - the box specified in the "Existing Box Name" dropdown will be used for the calculations.
Generates the leg load by bay report and saves it to an Excel file under Reports folder of the current model folder. After creation the Excel file will be opened on the screen.
