Standard Fixed Portal Frame


In the diagram I'm displaying my interpretation of the standard 'fixed' portal frame as observed in the 2007 Construction and Structures 1 and the 2008 Construction and Structures 2 classes.  The diagram illustrates the standard of most factories built in Australia today as the 'pinned' portal frame is rarely used anymore due to the need for extra on-site labour and speed of assembly issues.  The fixed frame is also favored as it allows for larger open spaces between stanchions than the pinned; this is because the fixed frame relies on its rigidity and distribution of loads into the footing system, allowing for minimal cross-bracing, while the pinned frame allows flexing and thus requires cross-bracing to limit this movement, closing up the space between stanchions.
