讲座内容:报告题目： Smart Seismic Control System 报 告 人： Professor Shirley J. Dyke, Ph.D., P.E. 美国华盛顿大学最年轻的冠名教授 美国ASCE结构控制技术委员会主席 现场口译： 刘林 副教授 报告日期： 10月21日（周六）下午3时 地 点： 土建综合楼702 内容简介： Smart damping devices are being examined by researchers around the world as a means of mitigating the dynamic effects of seismic loads on civil engineering structures. These devices have attracted significant attention recently because they provide controllable damping characteristics in a device that is inherently stable and has minimal power requirements. Currently devices in this class appear to offer the best opportunity for widespread acceptance of these innovative control techniques by the civil engineering community. Magnetorheological (MR) dampers are one of the most promising devices in this class. Both experimental and analytical studies have demonstrated that the performance of MR dampers is superior to that of comparable passive systems. In some cases, these devices also outperform comparable active systems. This presentation will focus on the application of MR dampers to buildings for response modification of structures subjected to seismic inputs. Phenomenological models, nonlinear system identification techniques, effective control algorithms, placement strategy for use with these devices will be discussed.
