Abstract: A new mathematic model of location optimization for displacement-based energy dissipative devices subjected to earthquake was proposed, expressed as a linear combination of three non-dimensional items which can assess both security and cosiness. Three performance indices were considered in this model. Five kinds of combination modes of the three indices in optimal function are then supposed. To obtain the optimal coefficients combination of the three indices, non-linear step-by-step time history analyses are carried out. This paper dealt with the response control when these dampers were optimally located for several building models with different number of stores and ground motions. Numerical analyses using genetic algorithms verify the validity and feasibility of the new objective function and some meaningful conclusions are given.
