It was brought to my attention in the "XBRACING.xls" spreadsheet workbook, off to the right side of the main calculation page, that there was a typo error in each of the calculation sheets for the area displayed for a 1-1/4" diameter rod. The digits themselves were correct, but I had the decimal point in the wrong location, making the area 1/10th of what it should have been.
This has been corrected, and the workbook is now version 1.2.

I was brought to my attention that in the "XBRACING.xls" workbook in the X(4), X(7), and X(10) worksheets there were a few incorrect cell references in the Member Data table for the drift analysis which resulted in the display of some incorrect column segment lengths and X-bracing lengths. The correct lengths of these members were displayed in the sketch. The incorrect values shown in the table did not effect the results, as the values (cell references) in the table were not used anywhere else.
This workbook is now version 1.1.
