Load Report

The load report is a tool that sums the loads applied to a given structural element. There are serviceability and factored values of loads. Serviceability values of loads come from the database; whereas, factored values are calculated by multiplying serviceability values by the appropriate load factors.

In Robot, the option applies to planar loads resulting from dead loads. Dead loads include loads caused by:

• Surface weight (weight of roofing, cladding, insulation, and so on)
• Density (weight of constructional materials, embankment materials, and so on).

This option is a handy calculator for preparing load reports. Calculated load values are not transferred to load records. You define load values for individual load cases using the values calculated in the following dialog.

Note: After changing unit loads in the database, load values are not updated.

Open the Load Report using either method:

• Click Loads menu > Special Loads > Load Report.
• Click .

The option is available for all structure types in Robot.

The left side of the dialog has options for calculating as well as saving and reading a load report:

• List of set selection, which is a list of the saved load sets. This field also lets you define a name of a new load set. The name (label) of a set is used as its identifier and is provided in a note.

  Above the set selection list are the following buttons:

  • New - Defines a new set name. (Current load set is deleted.)
  • Save - Saves the load set being defined.
  • Delete - Deletes the currently selected set from the list.
  • Note - Opens the text editor with data from the current load report.

  Under the set selection list the following icons are provided:

  • - Moves the currently selected line up one position in the load report table.
  • - Moves the currently selected line down one position in the load report table.
  • - Deletes the currently selected line from the load report table.
  • - Deletes all the lines from the load report table.
• In the Load report table, data for the total load is displayed. Each table record includes:
  • Load name.
  • Unit load value (density or planar load) from the database.
  • Layer thickness value - For density, the value can be changed. The default value is 10 cm (for planar loads, this field is not available). Section dimensions are the units of measurement.
  • Value for serviceability loading:
    • For density, it is: (unit weight)*(thickness).
    • For planar loads, it is a unit weight.

    load unit: force/length^2

  • Value of the Load factor Gf - Default values are saved and taken from the database.
  • Value of the Factored loading equals the product (serviceability loading)* (load factor)

    unit: force/length^2

  The last table row displays the totals of serviceability and factored loading. It also specifies a value of the average load factor, which is the quotient of the sum of factored loads and the sum of serviceability loads.

• Under the table, there are the options for calculating the concentrated or linear forces resulting from the (serviceability and factored) planar load p.
  • Concentrated load - Calculated as the following product: A*B*p, unit: force.
  • Linear load - Calculated as the following product: A*p (B dimension is inaccessible), unit: force/length.
  • Planar load: Is the value of p (dimensions A, B are not available), unit: force/length^2.

The right side of the dialog has options that support the unit load database:

• The Loads option lets you select a load from the database. You can transfer a load to the load report by clicking the < button.
• The Database field displays the name of the current database of unit loads. The current database can be selected in the Job Preferences
• The contents of the selection list depend on the selected load type: Material weight, Element weight, Soil weight or Variable loads. The selection of the material type depends on the database contents (NAME field, GROUPS table): Concrete, Timber-derivative materials, Roofing, and so on.
• Table for viewing and selecting unit load data - Table elements cannot be changed; the table has columns saved in the load database (DATA table):
  • Material (the field DATA:NAME)
  • Weight (the field DATA:LOAD)

  A weight unit depends on the selected type. If it is material weight, then force/length^3 is the unit. If it is element weight, then force/length^2 is the unit.

• Clicking Edit load database opens the dialog for database modification.
