摘要
为提高混凝土异形柱的承载力,本文提出一种新型实腹式钢骨混凝土异形柱。为了解这种新型钢骨混凝土异形柱的受力性能及破坏机理,本文通过对3根十字形钢骨混凝土异形柱和1根钢筋混凝土异形柱的轴心受压的试验研究,分析了钢骨混凝土异形柱和普通混凝土异形柱在轴心压力作用下的破坏形态以及试验过程中各种材料的受力状态。试验结果表明在轴心荷载的作用下,从弹性阶段到开裂荷载直至极限荷载,型钢与混凝土能保持协同工作,这种新型构件中各种材料的力学性能均能得到充分发挥,钢骨的存在改善了构件的延性。本文提出的新型实腹式钢骨混凝土异形柱受力性能良好,可以应用于工程。
To improve load-bearing capacity of the specially-shaped concrete columns,the solid-web steel reinforcement is used.To declare the mechanical property and failure behavior of the new specially-shaped steel reinforced concrete columns,experimental studies were conducted on 3 specially-shaped steel reinforced concrete columns and 1 specially-shaped reinforced concrete column in axial compression.the failure patterns of the steel reinforced concrete columns and the reinforced concrete column,and the stress state of the material in the columns during the tests are presented.The testing results indicate that steel and reinforced concrete in this type of steel reinforced concrete columns can work well together under the axial compression and the steel improves the ductility of the columns.So the mechanical property of the new specially-shaped solid-web steel reinforced concrete columns is wonderful.
