S/C: U.S. - Korea Joint Research on Hybrid System for Seismic Structures with Resonant Dampers and Robust Multiobjective Controllers

密苏里大学罗拉分校（UMR）和韩国科学技术院（KAIST）提出了一项联合研究项目，对抗震结构的混合系统进行实验和分析研究。创新的系统将通过集成调谐粘性阻尼器和主动肌腱控制器来开发。粘性阻尼器的设计对周围温度和自热的敏感性较低，并且能够消除结构的临界或故障模式。主动控制将提供必要的力量，使结构在规定的限制范围内作出反应。该混合系统能有效地控制结构在大范围地震烈度、风力和其他动力激励下的响应。它的适应性使其适用于低层和高层建筑。该项目的美国部分涉及一个由UMR土木，机械和电气工程研究人员组成的跨学科团队。该团队将重点研究控制算法及其鲁棒性，制造混合装置，控制参数的实验验证，以及模型结构响应的振动台测试。韩国的跨学科研究团队将专注于大量结构的数值分析、风洞测试、混合系统应用的可行性研究以及全面实验的准备。＊＊＊

9302201 Cheng A joint research project between the University of Missouri Rolla (UMR) and the Korea Advanced Institute of Science and Technology (KAIST) is proposed to experimentally and analytically study a hybrid system for seismic resistant structures. The innovative system will be developed by integrating tuned viscous dampers with active tendon controllers. The viscous damper will be designed with low sensitivity to surrounding temperature and self heating as well as the ability to damp out a structure's critical or offending mode. Active control will provide the forces necessary to bring structural response within prescribed constraints. The hybrid system is effective in controlling structural response over a wide range of earthquake intensity, wind force and other types of dynamic excitations. Its adaptability allows application to low and high rise buildings. The USA component of this project involves an interdisciplinary team consisting of researchers in civil, mechanical, and electrical engineering at UMR. This team will emphasize a control algorithm and its robustness, manufacturing hybrid devices, experimental verification of control parameters, and a shaking table test of model structural response. Korea's interdisciplinary research team will focus on numerical analysis of a large number of structures, wind tunnel testing, feasibility studies for the hybrid system's application, and preparation for full scale experiments. ***
