Yapıların deprem etkilerini en az hasarla atlatması ve depremden sonra da ayakta kalmasını sağlamak amacıyla bazı yapı koruma sistemleri geliştirilmiş, ve bunların bazıları da uygulamaya konmuştur. Burada incelenecek yapı koruma sistemleri üç gruba ayrılmıştır: •Taban Koruma Sistemleri •Yapı içine Yerleştirilen Pasif Enerji Sönümleyen Sistemler •Aktif Kontrol Sistemleri Yapıdaki kayma kuvvetlerini karşılamak amacıyla çeşitli pasif kontrol metodları ve araçları geliştirilmiştir. Pasif kontrol araçlarının özelliği o bölgede meydana gelmesi muhtemel en büyük deprem şiddeti gözönüne alınarak tasarlanmaktadır. Öte yandan, aktif kontrol sistemleri yapıya uygulayacakları kontrol kuvvetini deprem etkisine göre, depremin meydana geldiği anda düzenlerler. Bu yazı kapsamında pasif ve aktif kontrol sistemleri genel olarak tanıtılacak ve sonuç bölümünde de avantajlı ve dezavantajlı yanları tartışılacaktır.
In structural engineering, some structural protection systems have been developed so that buildings can be better protected against earthquakes and so that they can survive its effects. Some of these systems have been put into practise. Structural protective systems which are analyzed here can be divided into three main groups: •Base Isolation Systems •Passive Energy Dissipation Systems that are placed in buildings •Active Structural Control Systems Many methods and several types of dampers have been developed in order to reduce shear forces acting on the structural frames. The dynamic properties of such dampers are to be determined according to the intensity level of the design earthquake ground motion, because the yield strength, the energy dissipation capacity and the ductility factor of the damper are highly inşuenced by the input disturbance level. Response control by means of passive dampers should be most effective at the design level earthquake excitation, which is the key feature of this method. On the other hand, active control systems organize the control force it will apply on the building according to the effect of the earthquake, on the very moment the earthquake happens. Within the framework of this study, passive and active control systems will be presented in general. The proposal of "Seismic Response Control of Structural Systems" is based not only on the desire of completing the structural engineering free from earthquake disasters but also on the recognition of the seismic resistant design’s limitation and on the availability of new generation technologies such as microprocessors, sensors and actuators and so forth.
