摘要：

There　was　shortcoming　in　seismic　design　of　infilled　walls-frame　structures　in　the　present　codes.　The　mechanical　model　of　spatial　infilled　frame　structure　was　set　up　by　adopting　the　equivalent　diagonal　bracing　mode,　for　which　the　character　applied　to　the　horizontal　earthquake　action　to　masonry　infilled　walls-frame　structures　can　be　shown,　in　combination　with　the　failure　mode　of　infilled　walls.　Three　spatial　models　of　frame　structures　with　the　slabs　were　provided　with　well-proportioned　or　disproportional　infilled　walls　vertically,　or　without　infilled　walls.　And　then　the　pushover　analysis　of　each　model　was　carried　out　by　two　common　load　patterns.　Such　seismic　indicators　were　analyzed　and　compared　as　the　relationship　curve　of　base　shear　force　and　roof　lateral　displacement,　and　plastic　hinges　distribution　under　different　earthquake　criteria.　The　analysis　results　can　be　referred　as　seismic　design,　performance　evaluation　and　reinforcement　design　for　frame　structures.
