A systematic introduction about the basic theory of FSI（Fluid-Structure Interaction）,including basic concept and classification by interaction mechanism was first provided.Strong coupling method and weak coupling method were discussed and studied on the computation procedure and conditions.Then some successful analysis methods and progress for FSI such as ALE（Arbitrary Lagrangian-Eulerian） method,Meshless method,CBS（characteristic-based-split） finite element method and FCBI（flow-condition-based interpolation） finite element method were briefly described.The application and development of FSI theories in the domestic and abroad civil engineering areas were discussed in details.Research prospect on the FSI theory and its application was finally presented.
