摘　　要：近年来,不少地区地震事故频发,造成了大量的人员伤亡及财产损失。为此,文中开展基于模糊逻辑控制算法的抗震减震效果研究,以为后续地震安全预警机制奠定理论分析基础的同时,在地震初期进行预警,为人们争取宝贵的逃生时间。通过引入一个在OpenSEES软件中创建的11层建筑结构模型,在Matlab中引入隶属函数并制定模糊规则,将楼层位移和速度作为输入量进行仿真分析;其次,分析对比无控制和模糊控制两种状态下模糊逻辑控制系统的抗震减震效果。结果表明,该系统有明显的抗震减震效果,在模糊控制状态下,建筑结构框架的位移、加速度等均有减少,其中对于顶层峰值位移的响应控制率达到58.3%,而对于顶层峰值加速度响应控制率达到27.4%。In recent years,earthquake accidents have occurred frequently in many regions,resulting in a large number of casualties and property losses.Thereforce,the research on seismic andstance and shock absorption effect based on fuzzy logic control algorithm is carried out to conduct the early warning at the early stage of the earthquake,so as to gain valuable escape time for people,while laying the theoretical analysis foundation for the follow⁃up earthquake safety early warning mechanism.By introducing an 11⁃storey building structure model created in OpenSEES software,the membership function is introduced in Matlab to formulate fuzzy rules,and the floor displacement and speed are taken as inputs to conduct the simulation analysis.The stance and shock absorption effects of the fuzzy logic control system under the two states of no control and fuzzy control are analyzed and compared.The results show that the system has obvious seismic and vibration reduction effect.Under the fuzzy control state,the displacement and acceleration of the building structure frame are reduced,and the response control rate for the peak displacement of the top floor is 58.3%,while the response control rate for the peak acceleration of the top floor is 27.4%.
