A STUDY ON RESPONSE CHARACTERISTIC OF BUILDING-APPENDAGE STRUCTURE FOR EARTHQUAKE MOTIONS WITH TWO GROUND PREDOMINANT PERIODS

An investigation of the maximum acceleration amplification factor of the response spectrum for constant damping ratio revealed that the amplification could be divided into two groups. It is noted, that earthquake motions may have the same variance but different mean. In order to simulate the characteristics of the response spectrum an analysis that assumed two ground predominant periods for the simulated earthquake was made. The characteristics of the building structure and the building-appendage structure are represented by one and two-degrees of freedom systems. Test results indicate that the two predominant periods in the simulated earthquake can be adapted to earthquake motion not only in the magntiude of the acceleration amplification factor, but also in the shape of the spectrum. The effect of the system parameters such as the mass ratio of the appendage to building and the damping ratio of the appendage was clearly evident when using the simulated earthquake analysis.
