Animation for modes of vibrations
Animation for Modes of vibrations is introduced to visualize structuralbehavior when subjected to EQ loads
By viewing animation user can get an idea about weak elements. Suchweak elements can be strengthened by increasing their stifnnesses (sizes).

Modal Masses
As per IS 1893 (Part I) : 2002 clause 3.20 Modal Mass (Mk) of a structure
subjected to horizontal or vertical, as the case may be, ground motion is a
part of the total seismic mass of the structure that is effective in mode k of
vibration. The modal mass for a given mode has a unique value
irrespective of scaling of the mode shapes.Modal mass of mode K is given by
n
[ Wi ik]2
i = 1
MK=n
g Wi (ik)2
i = 1
Where
g = Acceleration due to gravity,ik = Mode shape coefficient at floor i in mode k
Wi = Seismic weight of floor i
