Defines the percentage of the roof and snow weights that are to be considered as supported by the shell for API-650 Appendix E checks.
If the supported cone roof design procedures are implemented, the software determines
the % of weight supported by the shell internally. This value will not be used.
If you do not enter a value in Weight of Roof Plates and % of Weights Supported by Shell, the software defines the value for % of Weights Supported by Shell as 100.
