While finding out time period, we have to select the modes(1-12), what are these modes and why does the time period changes for different modes.
For example:
For mode 1 Time period= 0.459
For mode 3 Time period=0.385
Asalam-o-alaikum,
what the term mode means and how we compute the mode?
I've been told that mode is used to determine the time period of the building and the mode 1 has the maximum time period so no need to check further mode. is that correct?
and how we determine the mass participation of building through mode?
thanks.
