摘要: 在土-結構動力相互作用簡化分析中,基于彈性半無限地基的假定,采用雙自由度集總參數模型來簡化土層,建立了基于土層集總參數模型的土-結構動力相互作用的分析模型,主要研究了不同土層對上部結構地震反應的影響.分析了在中硬、中軟兩種場地上5層和15層結構的地震反應,并與剛性基礎假定下同樣結構的地震反應分析比較.結果表明,對比較剛性的結構考慮土-結構相互作用可能存在一定的有利因素;對高層建筑,土-結構相互作用可能導致結構在地震作用下的層間變形較大幅度增加,是不利因素.

Abstract: Based on the assumption of elastic half-space a 2D lumped parameters model was used to simplify soil foundation. An analysis model of soil-structure interaction was constructed based on the soil physical model for mainly studying the interaction between subsoil and superstructure. The seismic responses of both a 5-floors building and a IS-floors building were analyzed. The results obtained from the 2D lumped parameters model of both medium hard site and medium soft site were some valuable conclusions were obtained. compared with those derived from the rigid foundation model.
