9623811 Makris Semi-active dampers are receiving considerable attention for seismic protection applications, including such devices ranging from hydraulic dampers to electrorheological (ER) fluid dampers. The implementation of semi-active dampers in real structures is challenged by a number of fundamental research problems such as:a) Salability b) The required dynamic range c) Control models and algorithms; d) Viscous heating and temperature dependent effects. In this project a systematic effort is made to investigate the forementioned issues is proposed. Specifically: The hysteretic unique property of electrorheological dampers to develop a combination of hysteric and viscous forces will be further exploited to develop a practical solution to protection of structures from earthquakes. The entire project is based on a coordinated interdisciplinary effort with strong industrial support and collaboration. A comprehensive education program will move forward together with the research project to involve students in their class work, laboratory testings, and analytical investigations. This is a FY96 Career award. ***

9623811 Makris半主动阻尼器在抗震应用中受到了相当大的关注，包括从液压阻尼器到电流变(ER)流体阻尼器等设备。半主动阻尼器在实际结构中的应用受到许多基础性研究问题的挑战，如：a)可用性；b)所需的动态范围；c)控制模型和算法；d)粘性加热和温度相关效应。本课题对上述问题进行了系统的研究。具体地说：电流变阻尼器的滞回特性可以产生滞回和粘滞力的组合，将进一步开发出一种实用的结构抗震保护方案。整个项目基于跨学科的协调努力，并有强大的行业支持和协作。一个全面的教育计划将与研究项目一起推进，让学生参与他们的课堂作业、实验室测试和分析调查。这是96财年的职业奖项。***
