Passive Control Solutions Applied to Civil Constructions under Dynamic Load
Journal Title: Analele Universitatii "Eftimie Murgu" Resita. Fascicula de Inginerie - Year 2017, Vol 24, Issue 1
Abstract
In the paper an overview of passive control solutions used for reduction of vibration of civil engineering structures is presented and the special attention is put on the friction pendulum bearings applications as the example of facility supporting the frame building. The experimental results of the frame building equipped with friction pendulum bearing located on the vibration table is studied. The analysis covers the acceleration response of the frame in time domain as well as power amplitude spectrum for eleven levels of shaking table's horizontal excitation movement. On the basis of analysis the clasification of vibrations of the frame according to earthquake Intensity Modified Mercalli scale is performed. Discussion on effectivennes of friction pendulum depending on concave radius of the friction pendulum bearing and its friction coefficient is performed.
