Q about T of any building

[mousa]

hi all
if there a command to get the time period (T) of the building?
how to get the participation factor of each mode ?
thank you

There is no command that will give you periods, but using the eigen command you will get eigenvalues that you can later use to calculate the periods. Here you can find a script that calculates the periods given eigenvalues: http://opensees.berkeley.edu/wiki/index ... -bay_frame
