To mitigate the seismic collapse risks of elevated silo structures, this study adopted base isolation devices to enhance their seismic performance. A photovoltaic-grade ethylene-vinyl acetate (EVA) packaging project was selected as the research object. A finite element model incorporating base isolation was developed using IDA, and seismic fragility analysis was conducted. The maximum inter-story drift ratio was selected as the Engineering Demand Parameter (EDP), while Peak Ground Acceleration (PGA) was adopted as the Intensity Measure (IM). The seismic performance and failure probability of the original structure and the base-isolated structure were compared and analyzed. The results demonstrate that under the rare earthquake (PGA = 0.22 g), peak inter-story drift ratios are reduced by 65.8% (X-direction) and 51.07% (Y-direction) through base isolation. Furthermore, the progression of plastic hinges is effectively suppressed, and the soft-story collapse mechanism is eliminated. Under the rare earthquake, the collapse probability of the base-isolated structure is significantly reduced from 3.63% to 0.173%. Compared to the original structure, the base-isolated structure exhibits significantly better capability in resisting collapse risks induced by low-probability seismic events. This research provides a theoretical foundation and practical guidelines for the seismic isolation design of elevated silo structures.

为降低高架筒仓结构地震倒塌风险,以某光伏级乙烯-醋酸乙烯共聚物(EVA)包装楼工程为研究对象,基于增量动力分析(IDA)法构建基础隔震有限元模型,并开展地震易损性分析;选取最大层间位移角作为工程需求参数(EDP)、地面峰值加速度(PGA)作为地震动强度参数(IM),对比分析原结构与隔震结构的抗震性能及失效概率。研究结果表明:在罕遇地震(PGA = 0.22 g)作用下,通过基础隔震装置降低层间位移角峰值65.8%(X向)与51.07%(Y向),有效抑制塑性铰时序发展,消除软弱层倒塌机制;在罕遇地震作用下,隔震结构倒塌概率由3.63%显著降至0.173%;基础隔震装置相较于原结构能更好抵御小概率地震事件引起的倒塌风险。

为降低高架筒仓结构地震倒塌风险,以某光伏级乙烯-醋酸乙烯共聚物(EVA)包装楼工程为研究对象,基于增量动力分析(IDA)法构建基础隔震有限元模型,并开展地震易损性分析;选取最大层间位移角作为工程需求参数(EDP)、地面峰值加速度(PGA)作为地震动强度参数(IM),对比分析原结构与隔震结构的抗震性能及失效概率。研究结果表明:在罕遇地震(PGA = 0.22 g)作用下,通过基础隔震装置降低层间位移角峰值65.8%(X向)与51.07%(Y向),有效抑制塑性铰时序发展,消除软弱层倒塌机制;在罕遇地震作用下,隔震结构倒塌概率由3.63%显著降至0.173%;基础隔震装置相较于原结构能更好抵御小概率地震事件引起的倒塌风险。

To mitigate the seismic collapse risks of elevated silo structures, this study adopted base isolation devices to enhance their seismic performance. A photovoltaic-grade ethylene-vinyl acetate (EVA) packaging project was selected as the research object. A finite element model incorporating base isolation was developed using IDA, and seismic fragility analysis was conducted. The maximum inter-story drift ratio was selected as the Engineering Demand Parameter (EDP), while Peak Ground Acceleration (PGA) was adopted as the Intensity Measure (IM). The seismic performance and failure probability of the original structure and the base-isolated structure were compared and analyzed. The results demonstrate that under the rare earthquake (PGA = 0.22 g), peak inter-story drift ratios are reduced by 65.8% (X-direction) and 51.07% (Y-direction) through base isolation. Furthermore, the progression of plastic hinges is effectively suppressed, and the soft-story collapse mechanism is eliminated. Under the rare earthquake, the collapse probability of the base-isolated structure is significantly reduced from 3.63% to 0.173%. Compared to the original structure, the base-isolated structure exhibits significantly better capability in resisting collapse risks induced by low-probability seismic events. This research provides a theoretical foundation and practical guidelines for the seismic isolation design of elevated silo structures.
