摘要
由于一般形式的异形钢管混凝土柱其钢管壁对核心混凝土的约束作用远小于圆形钢管混凝土柱,为了改善异形钢管混凝土柱的受力性能,提出带约束拉杆异形钢管混凝土柱的新型组合结构形式,并对其在轴压和偏压下的基础力学性能进行试验研究和理论分析。这种结构构件形式是在异形截面(方形、矩形、L形、T形、十字形等)钢管混凝土柱中沿纵向每隔一定间距横截面上设置横向水平约束拉杆,以通过约束拉杆的拉结作用,增强钢管壁对混凝土的约束作用,从而改善异形钢管混凝土的受力性能。
     本论文作为带约束拉杆的异形钢管混凝土柱系列研究的一部分,主要是针对带约束拉杆十字形钢管混凝土柱,进一步深入研究其在轴心荷载作用下的力学性能。在模型试验和非线性有限元分析的基础上,研究约束拉杆直径大小、拉杆水平间距和钢管壁厚度等因素对其承载力和延性的影响,分析带约束拉杆十字形钢管混凝土柱在轴压条件下的工作性能和破坏机理,并对带约束拉杆十字形钢管混凝土轴压短柱进行荷载-变形全过程分析,还提出了轴压过程中钢板局部屈曲的有关系分析。
As to the binding force exerted on the core concrete by the tube wall, the ordinary special-shaped steel-tube is smaller than the round steel-tube. In order to improve the force bearing quality of special-shaped steel-tube, the construction department of South China University of Technology cooperated with Guangdong Architecture Designing Academy and propose a new type of assemble configuration. They also carry out the systematic experimental research and theory analysis of the basic dynamic capacity under the axis pressure and deflecting pressure. In the new configuration, the horizontal binding pull rod is established intermittently and vertically in the the column of special-shaped steel tube section (square, rectangle, L-shaped, T-shaped, crisscross-shaped), so the drawing force of binding rod will strengthen the binding effect of the tube wall to concrete and improve the force bearing quality of the special-shaped steel tube.
     As one part of the serials of research on the special-shaped steel tube with binding pulled bars, this paper mainly focuses on the concrete column of crisscross-shaped steel tube and make a further research on its dynamic capability under the load of axes. On the basis of sisteen model experiments and non-linearity limited analysis of axes press short column, the research is done to analyze how the diameter, the horizontal space between the pulled bars and the ply of the tube wall will effect bearing capacity and ductility. The crisscross-shaped steel-tube concrete rod’s working capability and breakage mechanism under the pressure of axes pressure is also studied. Drawing on the present available binding concrete construct relation model and combining with experimental data to have a mathematical analysis, we put forward an analytic formula of material construction relation model of binding crisscross-shaped concrete steel-tube, and have a whole-process analysis of loading-distortion to the crisscross-shaped concrete steel-tube with binding pulled-bars. What’s more , the simplified calculating method of axes pressure bearing force is also given. At last the paper makes an elementary study and research to the local buckling of the steel-tube with the crisscross-shaped binding pulled bar.
