Dead-Only Combination with Dead Soil Load (v8.1 - Bug 2371)

Sizer version 7.x and 8 used the load combinations 1.4D and 1.25D + 1.5Ds, where Ds is vertical dead load due to soil and plants; however, according to clause 4.1.3.2 (9) of NBCC 2010, the load combination should be 1.4D + 1.5Ds. This created a non-conservative value for the dead-only load combination when Ds loads were present, as from green roofs. This has been corrected and the only “dead-only” load combination used is 1.4D + 1.5Ds.
