摘要
目的为改善铅芯橡胶支座(LRB)隔震结构的减震效果和适用范围,并确定结构的优化参数和控制装置优化布局.方法提出3种磁流变阻尼器(MRD)与LRB混合方案,形成智能隔震结构,建立其动力分析模型,对7层智能隔震结构进行地震反应分析.结果3种混合方案的相对加速度峰值、相对速度峰值、相对位移峰值和层间剪力峰值分别比LRB隔震结构有不同程度的降低.建立智能隔震结构的优化设计模型,对混合方案3进行优化设计,各项地震反应均得到更好地控制.结论IHGA对智能隔震结构的参数和控制装置布局优化设计是有效的.
In order to improve the effect of shock absorption and applied scope of base-isolated structure with lead rubber bearing(LRB) and study its optimum parameter.Intelligent isolated structure including 3 kinds of hybrid projects with magnetorhrological damper(MRD) and LRB were proposed in the paper.The model of dynamic analysis of intelligent isolated structure was researched,and the kinematic differential equation was developed.Seismic response analysis of 7-story intelligent isolated structure was carried out Compared with sliding base-isolated structure,the peak value of various seismic responses of three hybrid projects with MRD and LRB were reduced.The optimal model for intelligent isolated structure is set up.The various earthquake responses of intelligent isolated structure get better control after it is optimized with IHGA.The results by exemplification show that IHGA is an efficient optimal method for the optimization of parameters and control equipments of intelligent isolated structure.
