摘要: The invention relates to a combined giant column composed of an irregular-section multi-cavity steel tube with built-in concrete-filled circular tube, and construction method thereof, belongs the field building. section form can be triangular, quadrilateral, pentagonal, hexagonal like, composite is formed under combination or single use different forms. A diaphragm plate welded square longitudinal stiffened rib plate, plate. High-strength concrete poured in tubes, strength higher than that recycled tube. bearing capacity axial compression partial improved; has important significance on improvement stress concentration hydration heat column; simple, convenient, economical effective beneficial popularization application design building structures.
