The program can now apply static seismic loading per the Chinese
GB50011-2010 (2016 edition) code.
Note: As GB50011-2010 static seismic was added in CONNECT
Edition V22 Update 6, in order to use the 2001 edition you must directly specify the
code year. Otherwise, the program will default to the latest code edition as is
typical for STAAD.Pro.
