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
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 ;
- 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 ;
- 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 ;
- 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 ;
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
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 |
Use Search to filter loads by text.
- clear all filters;
- if the checkbox is set, load sets will be created after pressing
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
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
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 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
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
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.
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.
To preview load sets of created predefined load case, execute
from the tree.Common Options
- export the table to Excel.
- copy the table to the clipboard.
