Abstract Reinforced concrete (RC) frame buildings are the most well-known sort of developments in urban India,
which are subjected to a few kinds of forces amid their lifetime, for example, static forces because of dead
and live loads and dynamic forces because of wind and earthquakes. Not at all like static forces, have amplitude, direction and location of dynamic forces, particularly because of earthquakes, fluctuated
altogether with time, causing impressive inactivity impacts on structures. Conduct of structures under unique forces relies on the dynamic qualities of structures which are controlled by both their mass and stiffness
properties, though the static conduct is exclusively needy upon the stiffness characteristics. Execution of
structures to a great extent relies upon the quality and deformability of constituent members, which is additionally connected to the internal design forces for the members. The interior design forces thus rely on
the precision of the strategy utilized in their analytical determination. Analyzing and designing structures
for static forces is a standard undertaking nowadays as a result of accessibility of moderate PCs and specific programs which can be utilized for the analysis.
Performance of building is carried out under dynamic loading by various parameter like story drift, story stiffness, mass and rigidity and others.

INTRODUCTION
Structural investigation is fundamentally worried about discovering the behavior of a physical structure
when subjected to force. This activity can be as load because of the heaviness of things, for example,
individuals, furniture, wind, snow, and so forth or some other sort of excitation, for example, a seismic
tremor, shaking of the ground because of an impact close-by, and so on. Fundamentally every one of
these loads are dynamic, including the self-weight of the structure on the grounds that sooner or later in
time these loads were not there. The distinction is made between the dynamic and the static investigation
based on whether the connected activity has enough quickening in contrast with the structure's natural
frequency. On the off chance that a load is connected adequately gradually, the inertia forces (Newton's
first law of movement) can be overlooked and the examination can be rearranged as static investigation.
Basic progression, in this manner, is a sort of basic examination which covers the conduct of structures
subjected to dynamic (activities having high increasing acceleration) loading.
Dynamic loads incorporate individuals, wind, waves, movement, tremors, and impacts. Any structure
can be subjected to dynamic stacking. Dynamic investigation can be utilized to discover dynamic
displacements, time history, and modular examination.
A dynamic examination is likewise identified with the latency forces created by a structure when it is
energized by methods for dynamic loads connected all of a sudden (e.g., wind impacts, blast, and
seismic tremor).
A static load is one which differs gradually. Dynamic load is one which changes with time decently fast
in contrast with the structure's common recurrence. On the off chance that it changes gradually, the
structure's reaction might be resolved with static investigation, however in the event that it fluctuates
rapidly (in respect to the structure's capacity to react), the reaction must be resolved with a dynamic
examination.
Dynamic investigation for straightforward structures can be completed physically, yet for complex
structures finite element analysis can be utilized to ascertain the mode shapes and frequencies.

CONCLUSIONS
Story drift is within the maximum limit as shown in figure 4, As per IS 1893:2016.
No Stiffness irregularity and mass irregularity at any floor as shown in figure 5 & 6.
Time period for X-direction 2.09 sec. and for Y-direction 2.05 sec.
As per the result, story max. / Avg. drift ratio is less than 1.5 as shown in fig.7, No torsion
generates at any floor.
We can say that they will act as rigid diaphragm or flexible diaphragm, as shown in fig.8.
As, per the results and for obtaining realistic behavior of any building/structure dynamic
analysis plays very important role.
