MODE CONTROL SEISMIC DESIGN WITH DYNAMIC MASS
This paper presents a new response control method for building structures against earthquakes by making use of the inertia element connected between mass points. The device is named as the dynamic mass which generates the force to be proportional to the acceleration difference between mass points. In this paper, two topics are introduced. One of them is the method which the natural period of structure can be elongated keeping its mode shapes. Next topic is the method that can be made all participation factors of higher modes into 0 except the 1st mode. It is very simple to make the suitable distribution of dynamic masses along height which is satisfied to the above situation. As a result, response shear coefficients of all stories become same, because the response for higher modes does not occur.
