COMPISITE COLUMN STRUCTURE FOR STEEL AND CONCRETE

摘要

PURPOSE: A steel concrete composite column structure is provided to improve compression performance of a composite column by delaying the buckling of an inner steel pipe column using first and second concrete. CONSTITUTION: A steel concrete composite column structure(100) comprises an inner steel pipe column(110), an outer steel pipe column(130), a first concrete part, and a second concrete part. The outer steel pipe column is installed outside the inner steel pipe column to be separated from the inner steel pipe column. The first concrete part is placed inside the inner steel pipe column. The second concrete part is placed between the inner and outer steel pipe columns.
