摘要
将某一实际的６层框架结构简化为由变截面梁单元组成的平面杆系结构，并考虑结构材料的非线性特性，将地基土视为粘弹性介质，详细研究了地基土—上部结构相互作用（ＳＳＩ）效应对人工塑性铰（ＡＰＨ）抗震性能的影响。将这样真实的ＳＳＩ体系做被动抗震控制分析尚属首次。本文的结论对上部结构抗震控制措施的设计具有一定的理论指导意义。
A real six story framed building is simpled as a plane structure of bar system being composed of variable section beam elements,the non linear characteristics of material of structural component is consided,and ground soils are regarded as viscoelastic material,the effects of soil structure interaction (SSI) on the aseismic characteristics of artificial plastic hinge (APH)are studied.The study work of passive control of aseismic structure considering SSI effects for such simulating really super structure can be consided as creative in the domestic and foreign.The results obtained in this paper can guide the design of aseismic structural control system.
