Dear All,

CAESAR 4.5 gave me the dynamic output as follows:

Who can tell me what 45 Z(F) means? The User's Mannual explained 45 X(1/M/P) but no 45 X(F) expressed.

45 Z (F)

45 - The maximum contributor to the total response came from the 45th mode.

Z - The maximum contributor to the total response came from the "Z direction" applied load.

(F)- The maximum contributor to the total response came from the 15th Force Set. Note there is only one digit to signify force set number so the sequence goes 1,2,...,9,A,B,...
