# Predefined Load Cases

Predefined Load Cases is a tool that helps to preview and create Load Sets with chosen settings and according to standards EN 13001 and Eurocode0.

To create Predefined Load Cases, execute Jobs - Job - Predefined Load Cases from the tree:

The following options have to be defined:

- Standard - the standard according to which load sets will be created;
- Category - category of the individual load based on a chosen standard. Category may be set both in the table for each load separately or to a number of loads by pressing button Apply to Selected;
- Load Factor - factor used for correcting default values of partial safety factor and dynamic factor. Load Factor may be set both in the table for each load separately or to a number of loads by pressing button Apply to Selected;
- Position - used to avoid putting individual loads either that have the same category or which do not act on a structure simultaneously into one load set. Position may be set both in the table for each load separately or to a number of loads by pressing button Apply to Selected;

Individual loads with position 0 all belong to one load set and are also put into the same load sets with other positions.

Example:

Predefined Load Case with different positions:

Predefined Load Case
Individual Load | Factor | Position
Wind | 1.13 | 0
Gravity | 1 | 0
Snow | 1.5 | 1

Created Load Sets

Load Set 1. Position 0 | Load Set 1. Position 1
--- | ---
Individual Load | Factor | Position | Individual Load | Factor | Position
Wind | 1.13 | 0 | Wind | 1.13 | 0
Gravity | 1 | 0 | Gravity | 1 | 0
|  |  | Snow | 1.5 | 1

- Logic - used to duplicate load set but with an opposite sign to Factor for all selected Individual Loads. Logic may be set both in the table for each load separately or to a number of loads by pressing button Apply to Selected;

  Example:

  Predefined Load Case with logic:

  Predefined Load Case
  Individual Load | Factor | Logic
  Gravity | 1 | No
  Wind | 1.13 | Yes
  Hoist | 1.5 | Yes

  Created Load Sets

  Load Set 1.1 | Load Set 1.2 | Load Set 1.3 | Load Set 1.4
  --- | --- | --- | ---
  Individual Load | Factor | Individual Load | Factor | Individual Load | Factor | Individual Load | Factor
  Gravity | 1 | Gravity | 1 | Gravity | 1 | Gravity | 1
  Wind | 1.13 | Wind | 1.13 | Wind | -1.13 | Wind | -1.13
  Hoist | 1.5 | Hoist | -1.5 | Hoist | 1.5 | Hoist | -1.5

Use Search to filter loads by text.

- clear all filters;

- if the checkbox is set, load sets will be created after pressing OK button;

Note: In case every individual load's category is set to "None", a relevant error message will appear.

To edit created predefined load case, execute Jobs - Job - Predefined Load Cases - Edit from the tree.

- open the window with information about chosen standard;

Look of the Information Window for EN 13001:

Look of the Information Window for Eurocode0:

# Dynamic Factors

Dynamic Factors button opens a window where dynamics factors may be edited. By default dynamic factors values are set according to the chosen standard.

Look of the Dynamic Factor Window for EN 13001:

Look of the Dynamic Factor Window for Eurocode0:

Note: In Preview Window dynamic factors for Eurocode0 will be labeled as ψi,j where i - stands for column number beginning with 0 and j - for row number beginning with 1.

Example:

For the table given above ψ2,7 = 0.3

# Cases

Choose Cases button opens a window where necessary cases for load sets may be chosen.

Look of the Cases Window for EN 13001:

Look of the Cases Window for Eurocode0:

# Preview

Preview button opens a window where possible load sets may be previewed before being created.

Note: In case any individual load's category is set to "None", a relevant warning will appear before Preview window is opened.

If the individual load's category is set to "None", that individual load will not be displayed in the table.

Note: In case there is no load set into which an individual load with a particular category can be put, a relevant warning will appear before Preview window is opened.

If the individual load can not be put into any load set, it will not be shown in the table either.

To preview load sets of created predefined load case, execute Jobs - Job - Predefined Load Cases - Preview from the tree.

## Common Options

- export the table to Excel.

- copy the table to the clipboard.
