- Abstract:
- In this paper, Lead Magnetroheological damper，LMRD, was taken as a kind of new damper designed to reduce effectively the seismic response of structures. The position optimization of LMRD in structure was to improve the damping effect of controlled structure in LMRD, and it was taken the optimal structural quadratic performance index loss produced from removing damper as optimization goal at the same time. The result showed that the optimal position of LMRD in structure was depended on the structural properties and parameters, which had little relevance to the type of seismic wave, when considering the loss of structural optimal quadratic performance index without LMRD as the optimization objective. Also, LMRD could control the horizontal displacement response of structure, under the seismic load, effectively, rather than the acceleration.
