The secondary members shall include Purlins, Girts and eave struts used to support the wall & roof cladding. Secondary members have certain functions. They act as struts that help in resisting part of the longitudinal loads that are applied on the building such as wind & earthquake loads and they provide lateral bracing to the compression flanges of the main frame members thereby increasing frame capacity. Secondary Members are also used as side runners, eave struts, fascia channels, door posts, window posts, rafter stays, column stays, base angles and other miscellaneous structural parts.
