Area Load Tributary Width and Magnitude Reporting (Bug 2108)

Automatically generated area loads on the lower half of walls are given a vertical tributary width that is derived from the upper half of the storey, so it includes the joist depth of the storey above when it shouldn’t. These incorrect widths are shown in the load lists in the load input screen and Design Results.

The incorrect width is used in creating the load intensity shown in these lists, so that the total load on the wall segment remains the same as if the correct tributary width was used. The line load created on the diaphragm and shown in plan view is also correct, so this problem has no impact on force generation or design
