| 摘 要： | 本文通过高强约束混凝土短柱的试验表明在混凝土短柱中,由于采用了密排箍筋约束混凝土的侧向变形,克服了高强混凝土的脆性,并使高强纵筋与高强混凝土很好地协同工作,大幅度提高混凝土短柱的强度及变形能力,使短柱具有良好的力学性能。根据试验结果,得出了短柱峰值荷载的计算公式,其计算值与试验值吻合较好。

| Abstract: | Experiments on the confined high-strength concrete short columns show that the closely spaced hoops in high-strength concrete improve the brittleness of high-strength concrete, limit the lateral deformation and increase its strength and ductility. Therefore, short columns possess good mechanical properties. Theoretical analysis was made. Formulae for calculating peak load acting on the short column are proposed. Results calculated by these formulae are compatible with that obtained by tests. |
