The　paper　presents　a　dynamic　analysis　model　for　frame-shear　wall　structures.　The　mode　expression　of　frame-shear　wall　structures　and　the　corresponding　derivatives　are　derived　using　Laplace　transformation　and　the　inverse　Laplace　transformation.　The　calculation　equation　of　frequency　and　the　corresponding　mode　is　acquired　based　on　the　boundary　conditions.　The　orthogonal　conditions　about　distributed　mass　and　distributed　stiffness　are　obtained　with　Betti　theorem.　The　seismic　response　of　the　frame-shear　wall　structure　is　solved　by　mode　superposition　method,　in　which　the　motion　equation　of　the　frame-shear　wall　structure　is　decoupled　based　on　the　orthogonal　conditions.　Finally,　the　correctness　of　the　presented　model　for　the　frame-shear　wall　structure　is　validated　by　comparison　with　the　finite-element　method.　©　2017,　Nanjing　Univ.　of　Aeronautics　an　Astronautics.　All　right　reserved.
