1 TUCN RESEARCH CONFERENCE Efficient use of energy in reducing structurl response to eceptionl lods using hybrid viscoelstic dmpers nd dvnced methods of frctionl order control Project mnger: Dr. Ing. Cristin I. Muresn Automtion Dept.

2 Summry Mitigtion of seismic effects upon civil structures (ppliction to one floor structure) Design of novel control strtegies for seismic mitigtion bsed on frctionl clculus (lso combined with optiml control) Novelty in terms of ppliction Novelty in terms of the tuning procedure Efficient use of energy (reducing the control effort) Comprison with clssicl ctive control strtegies

3 Objectives, Activities nd Epected Objective Activity Month Obtin study of the Comprtive study of eisting 1-3 Detiled report of stte of the rt ctive control methods the ctive control regrding seismic Study of the specific 2-3 methods nd mitigtion in civil problems ssocited to dmpers structures vibrtion control Study of the different types of 1-2 dmpers Obtin dynmic Development of 3-6 Mthemticl model model for civil mthemticl model for civil of civil structure structures structures Obtin frctionl order mthemticl model for hybrid viscoelstic dmpers Development of mthemticl model for viscoelstic dmpers using frctionl clculus 4-6 Frctionl order mthemticl model for viscoelstic dmpers
