COMPOSITE COLUMN CAPABLE OF MINIMIZING THE BUCKLING OF A STEEL PIPE AND A STEEL ROD BY IMPROVING BENDING AND TORSION PERFORMANCE AGAINST EXTERNAL PRESSURE

摘要

PURPOSE: A composite column is provided to minimize the compression performance degradation of a column due to fire or surrounding interference.;CONSTITUTION: A composite column(1000) comprises a steel pipe(100), a steel rod(200), a connection part(300), and concrete(400). The steel pipe is extended in one direction and forms an internal space(IS). The steel rod is extended in one direction and is positioned in the internal space. The connection part is extended in one direction and connects the steep pipe and rod by being positioned in the internal space. The concrete is filled in the internal space.;COPYRIGHT KIPO 2013
