Load Sets

Load Sets – the loads of different type acting on a structure at the same time. In SDC Verifier load sets are the combinations of Individual Loads multiplied on Factors.

LS = L1•F1 + L2•F2• +...+ Ln-1•Fn-1• + Ln•Fn

where LSLoad Set, L1 and F1Individual Load and Factor, n – the amount of Individual Loads in the Load Set.

To create a Load Set, execute Job - Load Sets - Add... from the main menu


The item is added with the factor 1. It is possible to edit the factors for each item in the table separately or set the factors for the selected items by pressing Set to selected.

Safety Factor is used in the calculation according to the standards.

Add Logic Factor duplicates Factor with opposite sign to Factor2 for all selected Individual Loads. For the Individual Load with two factors two Load Sets will be created. Factor2 can be defined manually.


Load Set with one logic individual load:

Load Set
Individual Load Factor 1 Factor 2
Wind 1.13  
Hoist 1.5 -1.5
Gravity 1  

Created Load Sets

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

Each of the created Load Sets will include this Individual Load with only one factor. In general, the amount of the created Load Sets will be equal to 2k, where k – the amount of Individual Loads with two factors. The second factor can be defined also manually.

Load Set concept:


In the Logical Load Set is possible to edit existing factors but not allowed to add the second factor to the Individual Loads.

There is a possibility to copy the items with factors from one Load Set to another. Use and .

The equivalent (Von Mises) stress is calculated by the following formula:

Create and Edit Multiple Load Sets

Create multiple Load Sets gives a possibility to create easily few Load Sets at once.


To create few Load Sets specify number of Load Sets and press .

It is possible to modify the titles of the factors in the table.

Existing Load Sets are highlight with gray color. It is possible to edit their factors but not possible to remove them.

Apply factor to all selected cells / apply factors diagonally to selected cells / clear factors from selected cells:
