Abstract:	傳統建築結構分析常假設基礎為固接、鉸接或彈性體，但事實上土壤是一種半無限域複雜的非線性材料。因此，對一些特別重要的公共設施會要求在設計分析中必須考慮「土壤結構互制效應」( Soil-Structure Interaction；SSI )對結構耐震能力的影響。本文中以土壤與結構互制作用分析之3D有限元素軟體MIDAS/GTS，分析在不同地震歷時作用情況下，建物與土層的動力行為，探討建物考慮及不考慮SSI分析結果之差異。分析結果顯示，當動力分析有考慮土壤-結構互制行為時，土壤之非線性應力-應變特性會消耗掉大部 In traditional structure analysis, the support conditions of the structure are always assumed as fixed, hinged or elastic spring. But in fact, the soil is an unbounded domain with complex nonlinear materials. Therefore, for some particular important publi
