Abstract: This article comprehensively introduces the structure design of a ultrahigh layer steel frame core wall structure. The frame columns are rectangle concrete-filled steel tubes. Small sized steel columns for structure are set in the frame-core wall. The cantilever beams of the outside whose lengths arrive at 1.5-10.5m, to players of the annex and the large-span steel roof on the main structure are analyzed by MIDAS/CEN. Correspondingly, the web plates of the steel beams on the standard layers, which are holed for equipments, are analyzed by ANSYS.
Keywords: steel frame-core wall structure; concrete-filled steel tubes; large-span; large holed web plates; the steel beams
