CAREER: Seismic Protection of Structures With Semi-Active Dampers

Makris半主动阻尼器在地震保护应用中受到相当大的关注，包括从液压阻尼器到电流变（ER）流体阻尼器的这种装置。 半主动阻尼器在真实的结构中的应用受到许多基础研究问题的挑战，例如：a）稳定性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。 在本项目中，提出了一个系统的努力，以调查上述问题。具体而言：电流变阻尼器的滞回特性的独特发展相结合的阻尼力和粘性力将被进一步开发，以开发一个实用的解决方案，以保护结构免受地震。 整个项目基于跨学科的协调努力，并得到了强大的工业支持和合作。 一个全面的教育计划将与研究项目一起向前推进，让学生参与课堂作业，实验室测试和分析调查。 这是一个FY96职业奖。 ***

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. ***
