Dynamic Response Analysis of MSCSS Constructed with Rubber Vibration Isolator

The seismic responses of the mega-sub controlled structural system (MSCSS) can be reduced effectively based on the combination of the construction and control theory. One of the main construction features of the MSCSS is the connection between the additional column and the mega beam. The rubber vibration isolator is proposed as a new connection mode between the above two components according to the base isolation technique. The dynamic responses of the MSCSS subjected to the earthquake excitation are investigated by employing the probability density evolution method. The analysis results are compared with the seismic responses of the MSCSS constructed with other connection modes. The results show that the seismic responses of the MSCSS constructed with rubber vibration isolator can be reduced effectively, but the effect is not better than the other connection modes.
