Abstract - A new control strategy to improve a tuned mass
damper (TMD) is developed for the vibrationcontrolofalarge
structure subjected to external disturbances. The feedback
gain of the proposed algorithm is linear to the response
acceleration of the primal system and it is optimized in the
frequency domain under a harmonic excitation. According to
this method both the feedback gain and the TMD parameters
are optimized in the frequency domain and they areexpressed
in a set of closed form solutions. The performance of the
proposed control method is discussed and comparedwiththat
of a passive TMD.
Key Words: TMD, Harmonic, Frequency, Algorithm,
Acceleration.
1. INTRODUCTION
During recent earthquakes, reinforced concrete structures
with deep spandrel girders and short columns failed or
sustained heavy damage particularly due to brittle shear
failure of the column. Reinforced concrete frames are
classified according to their anticipated failure modes.
Designing procedures for these structures are reviewed
critically and alternative methods are proposed. The field of
Earthquake Engineering has existed in our country for over
35 years now. Indian earthquake engineers have made
significant contributions to the seismic safety of several
important structures in the country.
1.1 LITERATURE REVIEW
1)Kenny C. S(1984) Spectral density functions of wind-
induced acceleration responses of Sydney Tower identify
natural frequencies of vibration of 0.10 Hz and 0.50 Hz for
the first mode and second mode respectively was analysed.
For natural frequencies and damping measurements. Two
accelerometers were installed in the Tower, one at Turret
Level 8 to monitor the first modevibrationsandonenearthe
Intermediate Anchorage Ring to monitor the second mode
vibrations.
2)Genda Chen(2001) The proposedprocedureisappliedto
place the dampers on the floors of the six story building for
maximum reduction of the accelerations under a stochastic
seismic load and 13 earthquake records. Numerical results
show that the multiple dampers can effectively reduce the
acceleration of the uncontrolled structure by 10–25% more
than a single damper. It is found that time-history analyses
indicate that the multiple dampers weighing 3% of total
structural weight can reduce the floor acceleration up to
40%. The multiple dampers can even suppress the peak of
acceleration responses due to impulsive excitations,whicha
single damper of equal mass cannot achieve.
3)Roberto villaverde(2003) Aninvestigationiscarried out
of a 13 story building to assess the viabilityandeffectiveness
of a recently proposed roof isolation system that aims at
reducing the response of building to earthquake. The roof
isolation system entails the intersection the flexible
laminated rubber bearing between building’s roof and the
columns that support it addition of viscous damper
connected between the roof and rest of the building. It is
based on the concept of vibration absorber.
4)Jerod G. Johnson(2003)gives feasibility of placing tuned
mass damper at top in the form of limber rooftop moment
frame to reduce seismic acceleration response. Six existing
structure were analytically studied using a suite of time
history and response spectra records. The analyses indicate
that there is an increase in fundamental period increase
generally esult in a decreaseinseismicaccelerationresponse
for the same time history and response spectra records.
5)Yogesh Ravindra Suryawanshi (2012) Carried out a
study of inner working of Tuned Mass Damper and
technology of TMD in Taipei 101 tower. The theory behind
this TMD is that, if a smaller mass is attached to a multi
degree of freedom system and tuned it precisely, it will help
to reduce the oscillation of the system in any direction. For
the efficient working its frequency should be tuned to the
fundamental frequency of the structure. Here in Taipei 101
tower in Taiwan a massive steel sphere is provided as TMD.
This massive steel sphere will counteract the building's
oscillations. For this optimization is essential to the efficient
working of the tuned mass damper system, as well as the
safety of the structure and inhabitants around it. As the
number of storeys are increasing day by day and buildings
reach greater and greater heights, tuned mass damper
technology is an essential part of maintaining the structural
integrity of the places. No power source is required for its
operation.
6)Ashish A. Mohite (2015) ATunedmassdamper(TMD)is
a device which compresses of a mass, and spring that is
attached to a structure to reduce the dynamic response of
the structure. The frequency of the damper is tuned to a
particular structural frequency so that when that frequency
is excited, the damper will resonate out of phase with the

structural motion. Taller become more susceptible to
dynamic excitations such as wind and seismic excitation. For
the structure safety and occupants comfort,thevibrations of
the tall buildings are serious concerns for both engineers
and architects. In order to mitigate the vibration, here
adopted Tuned Mass Damper.Tall buildingsandobservation
towers are occasionally vibrated under strong winds and
become uncomfortable for occupants. Therefore, to reduce
the vibration in those structures, various types of dampers
are being developed recently. However, there is nosure way
to predict the wind-induced response of a structure with a
damper system and to estimate the suppressing effects of
dampers under earthquake loadings. Here a symmetrical
moment resistance frame (MRF) three – dimensional model
with and without tuned mass damper analysed by using
software ETABS which is constructed from concrete, steel or
composite material. Moment resistance frames can be
sufficient for a building up to 20 storey. A tuned mass
damper (TMD) is placed on its top and through it to studyits
effects on structural response due to time history analysis
with and without the tuned mass damper (TMD) ina ETABS.
The result obtained from software analysis of 10th, 12th,
14th, 16th, 18th, and 21th storey building with and without
tuned mass damper and compare result with each otherand
found that it is more efficient in reducing acceleration and
displacement of structure.5% TMD is more efficient for
regular building. Provision of TMD is more efficient by
providing it on the top storey.
7)Haruna Ibrahim (2015) Preliminary results on the
passive control of the structural response of single degreeof
freedom (SDOF) and twodimensional multi-storeyedframes
using Tuned Mass Damper(TMD)arepresentedhere.Atfirst
a numerical analysis was developed to investigate the
response of a shear building fitted with a tune mass damper.
Then another numerical was developed to investigate the
response of a 2D frame model fittedand without TunedMass
Damper (TDM). From the study it was found that, tuned
mass damper can be effectively used for vibration control of
structures. Tuned mass damper (TMD) was more effective
when damping ratio of the structure is less. It is also
observed that due to increase in tuned mass damper
damping ratio, the movement of tuned mass damper is also
decreases. The most important feature of the TMDs is the
tuning of frequencies, that is, the frequency of the TMD is
made equal to the fundamental frequency of the structure.
Because of various uncertainties inherent in the properties
of both the TMD and the structure, perfect tuning is very
difficult to achieve. As a consequence, there comes multi-
tuned mass dampers(MTMDs)forbettertuning.Tunedmass
damper are designed to reduce wind responses on tall
buildings, this study is made to study the effectiveness of
using tuned mass damper for controlling vibration of
structure due to excitation force (wind). Based on the
simulation results, it shows that the response of the
structure subjected to excitation force system is relatively
higher without tuned mass damper which shows the
effectiveness of TDM in controlling the vibration on the
structure. It also observed that the displacementresponseis
decreased by increasing damping ratio of TMD.
3. CONCLUSION
If the structure not properly designed and constructed with
required quality they may cause large destruction of
structures due to earthquakes. Time history analysis is an
useful technique for seismic analysis of structure when the
structure shows nonlinear response. This method is step by
step analysis of the seismic responses of a structure to a
specified loading that may change with time. Interpretation
of result and conclusion. In the present work it is proposed
to carry out seismic analysis of multi story RCC buildings
using time history analysis method considering mass
irregularity at different floor levels. Manyofthestudieshave
shown seismic analysis of the RCC structures with different
irregularities such as mass irregularity,stiffnessandvertical
geometry irregularity.Whenevera structurehavingdifferent
irregularity, it is necessary to analyzing the building in
various earthquake zones. From many past studiesitisclear
that effect of earthquake on structure can be minimize by
providing shear wall, base isolation etc.

The feedback gain of the proposed algorithm is linear to the response acceleration of the primal system and it is optimized in the frequency domain under a harmonic excitation. According to this method both the feedback gain and the TMD parameters are optimized in the frequency domain and they areexpressed in a set of closed form solutions. The performance of the proposed control method is discussed and comparedwiththat of a passive TMD. Key Words: TMD, Harmonic, Frequency, Algorithm, Acceleration. 1. INTRODUCTION During recent earthquakes, reinforced concrete structures with deep spandrel girders and short columns failed or sustained heavy damage particularly due to brittle shear failure of the column. Reinforced concrete frames are classified according to their anticipated failure modes. Designing procedures for these structures are reviewed critically and alternative methods are proposed. The field of Earthquake Engineering has existed in our country for over 35 years now. Indian earthquake engineers have made significant contributions to the seismic safety of several important structures in the country. 1.1 LITERATURE REVIEW 1)Kenny C. S(1984) Spectral density functions of wind- induced acceleration responses of Sydney Tower identify natural frequencies of vibration of 0.10 Hz and 0.50 Hz for the first mode and second mode respectively was analysed. For natural frequencies and damping measurements. Two accelerometers were installed in the Tower, one at Turret Level 8 to monitor the first modevibrationsandonenearthe Intermediate Anchorage Ring to monitor the second mode vibrations. 2)Genda Chen(2001) The proposedprocedureisappliedto place the dampers on the floors of the six story building for maximum reduction of the accelerations under a stochastic seismic load and 13 earthquake records. Numerical results show that the multiple dampers can effectively reduce the acceleration of the uncontrolled structure by 10–25% more than a single damper. It is found that time-history analyses indicate that the multiple dampers weighing 3% of total structural weight can reduce the floor acceleration up to 40%. The multiple dampers can even suppress the peak of acceleration responses due to impulsive excitations,whicha single damper of equal mass cannot achieve. 3)Roberto villaverde(2003) Aninvestigationiscarried out of a 13 story building to assess the viabilityandeffectiveness of a recently proposed roof isolation system that aims at reducing the response of building to earthquake. The roof isolation system entails the intersection the flexible laminated rubber bearing between building’s roof and the columns that support it addition of viscous damper connected between the roof and rest of the building. It is based on the concept of vibration absorber. 4)Jerod G. Johnson(2003)gives feasibility of placing tuned mass damper at top in the form of limber rooftop moment frame to reduce seismic acceleration response. Six existing structure were analytically studied using a suite of time history and response spectra records. The analyses indicate that there is an increase in fundamental period increase generally esult in a decreaseinseismicaccelerationresponse for the same time history and response spectra records. 5)Yogesh Ravindra Suryawanshi (2012) Carried out a study of inner working of Tuned Mass Damper and technology of TMD in Taipei 101 tower. The theory behind this TMD is that, if a smaller mass is attached to a multi degree of freedom system and tuned it precisely, it will help to reduce the oscillation of the system in any direction. For the efficient working its frequency should be tuned to the fundamental frequency of the structure. Here in Taipei 101 tower in Taiwan a massive steel sphere is provided as TMD. This massive steel sphere will counteract the building's oscillations. For this optimization is essential to the efficient working of the tuned mass damper system, as well as the safety of the structure and inhabitants around it. As the number of storeys are increasing day by day and buildings reach greater and greater heights, tuned mass damper technology is an essential part of maintaining the structural integrity of the places. No power source is required for its operation. 6)Ashish A. Mohite (2015) ATunedmassdamper(TMD)is a device which compresses of a mass, and spring that is attached to a structure to reduce the dynamic response of the structure. The frequency of the damper is tuned to a particular structural frequency so that when that frequency is excited, the damper will resonate out of phase with the

Taller become more susceptible to dynamic excitations such as wind and seismic excitation. For the structure safety and occupants comfort,thevibrations of the tall buildings are serious concerns for both engineers and architects. In order to mitigate the vibration, here adopted Tuned Mass Damper.Tall buildingsandobservation towers are occasionally vibrated under strong winds and become uncomfortable for occupants. Therefore, to reduce the vibration in those structures, various types of dampers are being developed recently. However, there is nosure way to predict the wind-induced response of a structure with a damper system and to estimate the suppressing effects of dampers under earthquake loadings. Here a symmetrical moment resistance frame (MRF) three – dimensional model with and without tuned mass damper analysed by using software ETABS which is constructed from concrete, steel or composite material. Moment resistance frames can be sufficient for a building up to 20 storey. A tuned mass damper (TMD) is placed on its top and through it to studyits effects on structural response due to time history analysis with and without the tuned mass damper (TMD) ina ETABS. The result obtained from software analysis of 10th, 12th, 14th, 16th, 18th, and 21th storey building with and without tuned mass damper and compare result with each otherand found that it is more efficient in reducing acceleration and displacement of structure.5% TMD is more efficient for regular building. Provision of TMD is more efficient by providing it on the top storey. 7)Haruna Ibrahim (2015) Preliminary results on the passive control of the structural response of single degreeof freedom (SDOF) and twodimensional multi-storeyedframes using Tuned Mass Damper(TMD)arepresentedhere.Atfirst a numerical analysis was developed to investigate the response of a shear building fitted with a tune mass damper. Then another numerical was developed to investigate the response of a 2D frame model fittedand without TunedMass Damper (TDM). From the study it was found that, tuned mass damper can be effectively used for vibration control of structures. Tuned mass damper (TMD) was more effective when damping ratio of the structure is less. It is also observed that due to increase in tuned mass damper damping ratio, the movement of tuned mass damper is also decreases. The most important feature of the TMDs is the tuning of frequencies, that is, the frequency of the TMD is made equal to the fundamental frequency of the structure. Because of various uncertainties inherent in the properties of both the TMD and the structure, perfect tuning is very difficult to achieve. As a consequence, there comes multi- tuned mass dampers(MTMDs)forbettertuning.Tunedmass damper are designed to reduce wind responses on tall buildings, this study is made to study the effectiveness of using tuned mass damper for controlling vibration of structure due to excitation force (wind). Based on the simulation results, it shows that the response of the structure subjected to excitation force system is relatively higher without tuned mass damper which shows the effectiveness of TDM in controlling the vibration on the structure. It also observed that the displacementresponseis decreased by increasing damping ratio of TMD. 3. CONCLUSION If the structure not properly designed and constructed with required quality they may cause large destruction of structures due to earthquakes. Time history analysis is an useful technique for seismic analysis of structure when the structure shows nonlinear response. This method is step by step analysis of the seismic responses of a structure to a specified loading that may change with time. Interpretation of result and conclusion. In the present work it is proposed to carry out seismic analysis of multi story RCC buildings using time history analysis method considering mass irregularity at different floor levels. Manyofthestudieshave shown seismic analysis of the RCC structures with different irregularities such as mass irregularity,stiffnessandvertical geometry irregularity.Whenevera structurehavingdifferent irregularity, it is necessary to analyzing the building in various earthquake zones. From many past studiesitisclear that effect of earthquake on structure can be minimize by providing shear wall, base isolation etc. REFERENCES [1] K. T. Chen, C. H. Chou, S. H. Chang, and Y. H.
