Dear Amit,
Calculation of time period is sensitive to mass and stiffness. Empirical
time period given in the code can not be compared with the dynamic
analysis
of analytical model which will always differ as pointed out Sangeeta
and
others.

It is always better to work out the time period for the appropriate type
of
structure based on the empirical formula given in the code and use this
as
an input to STAAD PX and PZ ( time period in x and z dir). This period
given
by the user will be used by STAAD in calculating the base shear.
