腔内带钢筋笼多腔钢管混凝土巨型柱轴压性能试验研究
Experimental Study on Axial Compression Performance of Multi-Cell CFST Mega-Columns with Steel Reinforcement Cage Inside
摘要
Abstract
According to a mega-column from a super high-rise mega-frame structure, three 1/12 scaled multi-cell CFST mega-column models were tested under axial compression. All the geometric dimensions and the steel plates of the three specimens were same with eachother. Specimen 1 was made from concrete C30 with steel reinforcement cage inside; specimen 2 was made from concrete C40 without steel reinforcement cage; specimen 3 was made from concrete C40 with steel reinforcement cage inside. The load-bearing capacity, stiffness and its degeneration, residual deformation and failure characteristic of models have been compared and analyzed. The study shows that the multi-cell CFST mega-column with steel reinforcement cage inside has good ductility and good compression work performance. And it can be used in the design practical of engineering.关键词
