Magnitude of Concentrated Live Roof Joist Load ( Bug 2428)

When creating a concentrated live load for a roof joist, the program was creating the equivalent line load by dividing the 1.3 kN concentrated load by the 200 mm default width, as per NBCC 2010 table 4.1.5.9. However, it applied that line load over a distance of 750 mm, not 200 mm. (750 was the size of this load for the 2005 NBCC.) This created a default concentrated load 3.75 times larger than it should have been. This has been corrected.

Note that this was a problem only for the default load, if one typed in the 200 mm distance, or even just pressed the modify button without typing, the correct load length would be used.
