Overview of load groups

Features of load groups

  • Load Groups are an aid to building Combinations - both manually and using the Generator - and their use is entirely optional.
  • Once a Combination is built using Load Groups, the link to the Load Group is lost – the Combination is made up only of Loadcases. Only Loadcases and Combinations are analysed – Load Groups are not.
  • Each Load Group holds items of a single load type - e.g. “Dead” or “Live”...etc. - and can contain both multiple loadcases and other Load Groups
  • The fundamental Load Groups setting is the “Class” which is either “Inclusive” or “Exclusive”
    • When “Inclusive” – all loadcases are added at once into a combination
    • When “Exclusive” – loadcases are used one at a time in combinations. Thus for example, where an Exclusive Load Group contains four loadcases, the Generator will produce four combinations for all required combinations which include the group’s load Type (e.g. “Imposed”), each containing only one of the group’s four cases.

The load groups process

To make use of Load Groups you would proceed as follows:

  1. Define Loadcases as normal
  2. If required, create Load Groups from Loadcases and/or other Load Groups
  3. Create Combinations by combining Loadcases and/or Load Groups

The end result is Loadcases and Combinations (built up of factored loadcases). These are then run through analysis and design.
