Elastic Critical Load Factor

The Elastic Critical Load Factor check can be used in the portal frame checking process. It is unlikely that a portal frame will fall beneath the critical factor of 10 and so the check is usually not going to be an issue. Occasionally some of the non-portal minor members could give a factor under 10 and so should be checked. It is possible to omit some members from the check, eg, parapet members or canopies that are not going to influence the overall stability of the building. To omit members set the cursor into the large box at the bottom of the screen, then click on the individual members that you wish to omit. These particular members will be removed from the check. (The numbers of the omitted members appear in the box.)

For in depth details of the elastic critical load factor check see the relevant section in the MasterFrame manual (page 340) found in C:\Program Files\MasterSeries 2019\Doc.
