ABSTRACT

This paper investigates the performance of the Magnetorheological damper as a smart dissipating device in the isolated buildings for prevention of seismic pounding. To that end, an isolated building was modeled by considering the pounding effect with different gap distances. Multi-objective optimization was performed to optimize the fuzzy logic control of damper for each gap distance. The results showed that the optimized semi-active control system can prevent the pounding of the building and greatly improve the structure’s behavior as compared to the isolated pounded building and even to the case without the pounding at some considered gap distances.

智能阻尼器在近断层地震孤立结构防震中的应用

摘要

本文研究了磁流变阻尼器作为智能消散装置在隔离建筑物中防止地震冲击的性能。为此，通过考虑不同间隙距离的冲击效应对孤立的建筑物进行建模。进行多目标优化，以优化每个间隙距离的阻尼器模糊逻辑控制。结果表明，优化后的半主动控制系统可以防止建筑物的冲击，与孤立的冲击建筑物相比，甚至在某些考虑的间隙距离处没有冲击的情况下，都可以大大改善结构的性能。
